NOTES ON HIPPOBOSCIDE. 19. ADDITIONS TO THE LARGER SPECIES OF LYNCHIA, WITH DE-
SCRIPTIONS OF TWO NEW SPECIES
BY J. BEQUAERT
Department of Comparative Pathology and Tropical Medicine, Harvard Medical School and School of Public Health Material of the larger species of Lynchia studied since the publication of my earlier paper in 1933 (Psyche, XL, pp. 68- 82) has led me to modify some of my conclusions. Lynchia wolcotti Swenk appears to be a valid species and is here recog- nized as such. The African fly formerly referred to L. palustris was misidentified and is now described as a new species. An additional new species of this group is described from Ceylon. The following emended key supersedes that published in 1933.
1. Mesonotum and disk of scutellum densely and fairly uni- formly covered with soft, short hairs, directed backward; scutellum without median longitudinal groove. Frons very wide; inner margins of eyes distinctly converging below; postvertex very short and wide, about one-fourth to one-third the length of mediovertex; frontal bristles numerous, in several irregular rows. Palpi short, at most as long as fronto-clypeus. Wing membrane bare over much of the basal two-thirds (more extensively in the female than in the male). Subcosta (Sc) usually com- plete, ending in costa. Wing 5.5 to 7 mm. long. L. pilosa. Mesonotum almost bare, except for narrow patches of long hairs behind the humeral callosities and before the scutel- lum; scutellum with only a few lateral setae and apical fringes of soft hairs, the disk mostly bare. Palpi at least as long as fronto-clypeus. Upper side of wing mostly covered with microtrichia; only the axillary cell (2d An) or that cell and the hind fourth to half of the anal cell (Cul-1st An) bare . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2. 2.

Lynchia pilosa (Macquar t )
Olfersia pilosa Macquart, 1843. See J. Bequaert, 1933, p. 70. Additional reference: Olfersia pilosa Speiser, 1907, in Sjostedt, Wiss. Ergebn. Schwed. 2001. Exped. Kilimandjaro, 11, pt. 10, pp. 4 and 7 (off Choriotis kori, Kibonoto, Tanganyika Territory).
Male. - Head seen in front about one and one-quarter times as wide as high; frons at its narrowest about twice as wide as the eye, measured along inner orbits about as long as its greatest width at vertex, the sides converging strongly from vertex to fronto-clypeus in upper half and more gradually in lower half; inner orbits (parafrontalia) very broad, at their widest more than half the width of mediovertex (frontalia), divided into a narrow, smooth and bare juxta-ocular zone and a much wider alutacous inner zone bearing many soft, yellowish, reclining set2 in several irregular rows; one stiff, long black bristle at inner margin of parafrontalia near upper third and a few sim- ilar black bristles (one very long) near fronto-clypeus; one very long and thick, black vertical bristle; postvertex (vertical tri- angle) very short and wide, semi-elliptical with drawn-out sides, the anterior margin even, without median depression or pit, the occipital margin nearly straight; apex of fronto-clypeus with a narrow, deep median notch, the antero-lateral angles mod- erately produced. Palpi very short, thick, about as long as fronto-clypeus (measured from ptilinal suture to apical notch), covered with many long, black and yellowish setae. Dorsal appendage of second antenna1 segment short, with obtuse apex, bearing apically many long, stiff, black bristles, mostly curved downward. Thorax: anterior margin broadly concave; pro- notum exposed from above as a membranous sclerite, the hind margin of which overlaps the anterior margin of mesonoturn; humeral callosities short, broadly rounded off at apex; median notal and transverse mesonotal sutures deep and nearly com- plete. Scutellum transversely rectangular (somewhat as in Pseudolynchia), slightly over three times as wide as its greatest length, the anterior (mesonotal) margin nearly straight, the hind margin slightly convex medially, somewhat angular at the sides, without median groove or depression. Thorax (including scutellum) covered uniformly with numerous, short, soft, ap- pressed, yellowish hairs, directed backward and each arising from a small papula; the hairs are stiffer and black on the humeral callosities and notopleura; in addition there are long,
19451 Notes on Hippoboscidce 91
stiff, black bristles as follows: on each side, two on the humeral callosity, three or four at the hind corner of the notopleuron, one prealar, one postalar, one prescutellar, one scutellar (in the side corner), and six on the metepimeron; hind margin of scutel- lum densely fringed on the sides, weakly in the middle. Legs long and stout; femora much swollen, but without distinctive features; fourth tarsal segment of fore legs not produced, nor- mal; hind tarsal segments broader than usual, densely covered beneath with stiff, black bristles. Wing short and broad; micro- trichia covering the membrane except for the following areas: most of axillary cell (2d An), most of first basal cell (R), en- tire second basal cell (M), and basal half of the combined dis- cal and second posterior cells (Ma) ; first basal cell (R) long, narrow, parallel-sided; second basal cell (M) short, at most one-third of the length of the first, slightly widened apically and closed by a hyaline, unsclerotized, straight, vertical anterior basal cross-vein (Mg), the upper outer angle being nearly square; subcosta (Sc) usually complete, ending in costa; apical portion of costa (beyond tip of first longitudinal vein) moder- ately swollen, distinctly thicker than basal portion; longitudinal veins all crowded near anterior margin; costa densely setulose, all other veins bare. Abdomen: one very large sclerotized basal tergite, with straight hind margin, covered with many evenly distributed short setse; remainder of dorsum mostly soft and membranous, without sclerotized plates, uniformly covered with short setae and some larger and heavier ones at extreme sides; one large preanal, sclerotized tergite, sparsely covered with short setae and bearing on each side a group of ten to twelve very strong, spine-like bristles, three to five of which are much longer than the others and placed near the hind margin; venter entirely soft and membranous, fairly uniformly covered with short setae, posteriorly with much longer ones; before the genital opening a pair of small prominent lobes, sclerotized at the broadly rounded tips, which bear many long setae. Female. - Differs from the male in the following particulars. Frons relatively narrower, at its narrowest about one and two- thirds the width of an eye. Membrane of wing bare over about the basal two-thirds: microtrichia covering only the apical two- thirds to three-fourths of the first posterior cell (Rg), more ex- tensively along third longitudinal vein (Ri+ o) than at fourth longitudinal vein (Mi+2), the apical fifth to fourth of the com-
92 Psyche [March-June
biaed discal and second posterior cells (Mg), and a short area in the tip of the combined third posterior and anal cells (Cu+lst An).
Total length, from notch of fronto-clypeus to apex of abdomen (alcoholic specimens) : 5.5 to 7.5 mm.; length of wing: 5.5 to 7 mm. ; width of wing: 2.2 to 2.8 mm.
L. ftlom is isolated in the genus Lynchiu, owing to the uni- form covering of setdae on thorax and scutellum, the unusual development of the pronoturn, the crowding of the longitudinal veins toward the costa of the wing, and the sexual dimorphism in the extent of the microtrichia over the wing membrane. Most of these characters differentiate L. pilosa also from the smaller species of the genus Lynchia.
Additional Specimens. - KENYA COLONY: Mas& Reserve. - UGANDA: Katwe, Tom, one female and two males, off Lissotis m. melanogaster (Ruppell) (G. H. E. Hopkins), and one female, off Francolinus levaillanti mfilema Ogitvie-Graot (G, H. E. Hopkins). Maruanaita Hill, Gih, Karamojo, one female, with- out host (G. H. E. Hopkins). - SOUTHERN RHODESIA: Salis- bury, one male; without host (M. C. Z., Cambridge, Mass.). - BECHUANALAND: Ghanzi, Mongalatsila, off Choriotis kori (Bur- chell) (J. Maurice. - Brit. Mus.) . - ZULULAND: Nongomo, one male, "ex Paauw" (H. H. C~rson).~-Mo~occo: Tiznit, two females and one male, off Sandgrouse, Pterodes orknt~iis (Lime) (Col. R. Meinertzhagen) .
This species is now known from Zululand, the Orange Free State, Transvaal, Bechuanaland, Southern Rhodesia, Tangan- yika Territory, Kenya Colony, Uganda, southern Abyssinia and Morocco. It is normally a parasite of the Otitidse (Bus- tards, Koris or Knorhaans) and will probably be found wherever these birds occur. In particular, it should be looked for in the savannas of the Katanga and the northeastern Vele (Belgian Congo), where Bustards are fairly common. The occurrence of this fly on Sandgrouse in Morocco is of unusual interest. The flies were taken on this host in winter (November 6, 1938). Colonel Meinertzhagen (in Kit.) points out to me that "Sand- grouse inhabit much the same type of country as Bustard and in this particular area of Morocco the Bustard is not uncommon in spring and summer, but absent in winter. It is also to be ' "Paauw" is one of the vernacular names of the Bustards in South Africa.
194.5 I Notes on Hippoboscidx 93
noted that Bustard and Sandgrouse, though not in the least related, are the only bird groups which have a pinkish under- down." I suggest that Sandgrouse and Francolins act as facul- tative, and perhaps temporary, hosts for specimens of L. pilosa that hatch at the season when Bustards are absent. Bigot (1863, in Maillard, Notes sur File de la Reunion, 2d Ed., 11, p. M38) includes Olfersia pilosa in his list of the Dip- tera of Reunion. If this record was based on a specimen taken in Reunion, it was certainly an erroneous identification. Lynchia schoutedeni, new species

Lutz, Neiva and da Costa Lima (19 15, Mem. Inst. Osw. Cruz, VII, p. 183, PI. XXVIII, fig. 4), from the State of Piauhy, Brazil, shows that I was mistaken in referring to that species the African parasite of Cormorants. The true 0. palustris is one of the small species of Lynchia, the wing being about 5 mm. long. It is very closely related to, or possibly even identical with, Lynchia albipennis (Say) *l
'1 am indebted to the late Dr. Ad. Lutz for a cotype of Olfersia palustris, now deposited at the Museum of Comparative Zoology. I surmise that the length of the wing as given originally (7 mm.) was either an oversight or meant to cover the distance from the clypeus to the tips of the folded wings. It should be noted that the total length of the body as given (5 mm.) is too small for any of the large species of Lynchia.
19451 Notes on Hippoboscidce 97
For a long time I was undecided as to whether the African parasite were not Lynchia massonnati (Falcoz) (Ornithoponus massonnuti Falcoz, 1926, Faune de France, XIV, Dipteres Pupipares, p. 3 1, figs. 2 8-2 9), based upon the female fly off Platalea leucorodia, from the region of the Dombes, Dept. Ain, France, which Massonnat (1909, Ann. Univ. Lyon, N.S., FIG. 2. Lynchia majuscula J. Bequaert, n. sp., male holotype. A, head; B, ab- domen from above (right) and below (left). CXXVIII, p. 304, PI. V, figs. 40-42) had referred to Lynchia americana. While it seems fairly certain that Massonnat's fly was not the American Lynchia americana (Leach), it does not seem possible to regard it as identical with the African parasite of Cormorants. Neither Massonnat nor Falcoz mentions or fig- ures the peculiar brush-like setae on the sides of the abdomen. These are so characteristic of the female of L. schoutedeni that they could hardly have been overlooked. It is possible, how- ever, that Massonnat's specimen was really a male, in which case it might well have been my new species.
98 Psyche [March- June
Lynchia majuscula, new species
Female. - Head seen in front slightly wider than high; frons about twice as wide as eye, measured along inner orbits about one and one-third times as long as its width at vertex, with nearly parallel sides; inner orbits (parafrontalia) wide, slightly more than half the width of mediovertex (frontalia) ; frontal bristles reduced to a small group on the gena near lower edge of eye, and two or three on the middle; one very long vertical bristle; postvertex (vertical triangle) long, more or less tri- angular and broadly rounded anteriorly, nearly as long as wide and about half as long as mediovertex, apparently without median anterior depression or pit; occipital margin straight; fronto-clypeus of the usual shape, the antero-lateral angles moderately produced. Palpi unusually long and slender, only slightly shorter than the height of the head. Thorax: anterior margin straight medially; humeral callosities broad, moderately prominent, bluntly rounded at apex, with one long bristle and eight to ten short setae; anterior half of mesonotum (meso- scutum) on each side anteriorly with a narrow, transverse patch of short, soft hairs and a few setae, the patch not reaching the middle line; one very long prealar bristle; dorsal portion of mesopleura (notopleura) with a few scattered short setae and, posteriorly, with one long bristle; a few setae near outer hind margin of mesonotum and one long postalar bristle ; hind margin of scutellum evenly and moderately convex, weakly fringed and in each corner with one long scutellar bristle; metepimeron with 5 or 6 strong, short bristles and some softer setae. Legs without distinctive features; fourth tarsal segment of fore legs not pro- duced. Wing long and broad; microtrichia covering most of the membrane; axillary cell (2d An) bare, except for a very narrow zone along the sixth longitudinal vein (2d An) ; first basal cell (R) long, narrow, parallel-sided; second basal cell (M) less than half but over one-third of the length of the first, closed by a nearly vertical anterior basal cross-vein (Ms) ; subcosta (Sc) complete, ending in costa; costa densely setulose; third longi- tudinal vein (R4+5) with a few setulae close to the tip; other veins bare. Abdomen: a broad, short, transversely lozenge- shaped basal tergite, followed by a small transverse median sclerite; preanal tergite consisting of two elliptical plates, broadly connected medially and each bearing a group of eight
194.51 Notes on Bippoboscids 99
long bristles and a few shorter ones; remainder of dorsum soft and fairly uniformly covered with many short setae on small papulse; in addition the integument of the median area is micro- scopically, transversely stridate; ventrally there is apparently only one small, crescent-shaped sderite, placed immediately in front of the anal ring and more or less divided longitudinally; ventral surface uniformly covered with many setee, slightly FIG. 3.

longer than those of dorsum; soft portion of abdomen very superficially divided along the sides into five segments, each corresponding to one of the spiracles.
Total length, from notch of fronto-clypeus to apex of ab- domen (somewhat flattened on the slide): 8 mm.; length of wing: 9 mm.; width of wing: 3 mm.
Specimen Examined. -CEYLON: Holotype, female, off a Falcon, Spilornis cheela spilogaster (Biyth) , April, 1935 (sent by the late Dr. G. A. H. Bedford. - Mus. Comp. Zoiil.). L. m+scula appears to be most closely related to L. sckoute- den; described in this paper, agreeing with it in the char- acters of the wing. It is, however, slightly larger, being the largest member of the genus I have seen thus far. In addition to the differential characters given in the key, attention may be called to the difference in the pilosity of the dorsum of the ab- domen and in the shape of the postvertex. The description is based on a single specimen mounted on a slide in Canada balsam, after treatment with potash. It is pos- sible that the frontal bristles were actually more numerous on the fresh specimen.
Lynchia americana (Leach)
Feronia americana Leach, 18 17 ; Hippobosca bubonis Pack- ard, 1869. See J. Bequaert, 1933, p. 72. The synonymy, distribution and hosts of this fly will be dis- cussed fully in a forthcoming paper on the North American Hippoboscidae.
L. americana is one of the most common and widespread Nearctic hippoboscids. It is known in the Dominion of Canada from Ontario and Nova Scotia; and in the United States from Maine, New Hampshire, Vermont, Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, the District of Columbia, Virginia, West Virginia, North Caro- lina, South Carolina, Georgia, Florida, Alabama, Louisiana, Texas, Kentucky, Ohio, Indiana, Illinois, Wisconsin, Iowa, Nebraska, Minnesota, Kansas, Colorado and Nevada. Farther south it seems to be very rare, as I have seen only one specimen from Mexico (Grito) and one from Panama (Juan Diaz). The published records from California and the Galapagos were based on misidentifications.
The known host list is very large, but this species is most commonly found on diurnal and nocturnal birds of prey and on Ruffed Grouse. H. S. Peters ( 1935, Ann. Carnegie Mus., XXIV, p. 5 7) reported a specimen off an American Egret (Casmerodius albus egretta Gmelin) , with a Mallophagan (Esthiopterum botauri Osborn) attached, a most unusual find. The only record I have from a passerine host is a specimen taken at White Plains, New York, off a White-throated Sparrow, Zonotrichia albicollis (Gmelin), by Mr. C. Parley. L. americana has become established on the introduced Ring-necked Pheasant, Phasianus colchicus torquatus Gmelin.
Since this paper was sent to press, I received from Dr. A. Stone several specimens of L. americana taken off Wild Turkey in North Carolina (Durham; Rockingham Co.) and Mississippi (Picayune).
The statement in my earlier paper (1933, p. 75) regarding the occurrence of pupae in the ears of Great Horned Owl, should be deleted. In C. W. Johnson's paper it refers to Oynithoica vicina (Walker) (cited as 0. confluenta).

Lynchia fusca (Macquart )
Olfersia fusca Macquart, 1845.
See J. Bequaert, 1933, p.
77l; 1940, Rev. Acad. Colombiana Cienc. Ex. Fis. Nat., 111, pt. 12, p. 416; 1943, Jl. of Parasitology, XXIX, p. 132. This species will be more fully discussed in a forthcoming paper.
L. fusca is fairly common in Oregon and California, but it is also found occasionally in the eastern United States (South Carolina, Georgia, Florida, Texas, Tennessee, Kansas, Colo- rado, and Michigan). It was originally described from Colom- bia, and has also been taken in Panama and Brazil. It is mainly found on Owls, more rarely on diurnal birds of prey.
Lynchia wolcotti (Swenk)
Olfersia wolcotti Swenk, 1916, Jl. New York Ent. Soc., XXIV, p. 132 (no sex. Michigan: Ann Arbor, off Buteo platypterus) . My surmise that 0. wolcotti might be a synonym of L. fusca (J. Bequaert, 1933, p. 78) was incorrect. Through the courtesy of the late Prof. Myron H. Swenk, I was able to study the type now in the Department of Entomology, University of Nebraska. Specimens Examined. - MICHIGAN: Ann Arbor, off Buteo p. platypterus (R. H. Wolcott. - Holotype) . McMillan, off Accipiter v. velox (0. M. Bryens, June 6, 1933; recorded also by H. S. Peters, 1936, Bird-Banding, VII, p. 13). -NEBRASKA: Lincoln, off Buteo p. platypterus (C. E. Mickel) . - PANAMA: El Volcan, Chiriqui, July 6, 193 7, off a Hawk (C. B. Worth). Apparently a rare species, which has been taken thus far only from diurnal birds of prey.
Lynchia nigra (Perty )
Hippobosca *a Perty, 1833 ; Ornithomyia intertropica Walker, 1849; Olfersia acarta Speiser, 1902. See J. Bequaert, 1933, p. 792; 1933, Proc. California Ac. Sci., (4) XXI, p. 134; The reference to Ad. Lutz, Neiva and da Costa Lima, 1915, Mem. Inst. Osw. Cruz, VII, p.
182, should be deleted. These authors undoubtedly referred to L. fusca some of the smaller Lynchice and their specimens seem to have been at least partly L. angustifrons (v. d. Wulp). The latter is a valid, distinct species, not a synonym of L. fusca. The flies off Owls, which Ad. Lutz, Neiva and da Costa Lima (op. cit., p. 181) called Olfersia nigra Perty, were almost certainly Lynchia fusca (Macquart) .

In North America L. n@a is known from British Columbia, Quebec, New York, Kansas, Colorado, Utah, Arizona, New Mexico, Montana and Texas. It has also been taken in the Galapagos, Hawaii, and Bolivia.
All the known hosts are diurnal birds of prey. Lynchia dukei ( Aus ten)
Olfersia duke; Austen, 1911. See J. Bequaert, 1933, p. 80. Since publishing this paper I have examined the type at the British Museum.
Additional Specimens. - BELGIAN CONGO: Butiaba, Lake Albert, off Haliceetus vocif er (Daudin) (A. Meinertzhagen) . The specimen previously recorded from Ganda Sundi was off Hieraaetus ayresii (Gurney). - CAMEROON: Metet, off a Hawk Osw. Cruz, VII, p. 181) should be deleted. The specimens which these authors referred to L. nigra were almost certainly L. jusca (Macquart), while their Olfersia raptatom was possibly L. nigra.

L. dukei is strictly Ethiopian and known at present from Cameroon, French Congo, Belgian Congo, Abyssinia, Uganda, Kenya Colony and Tanganyika Territory. It is the African representative of the New World L. nigra, from which it is pos- sibly not specifically distinct.
Like L. nigra, it is known only from diurnal birds of prey. Unrecognized Species
Several of the described, larger species of Lynchia cannot be recognized with certainty from the inadequate descriptions. Some of them are evidently synonyms of the species recognized in this paper.
1. Lynchia massomati (Falcoz, 1926). See J. Bequaert, 1933, p. 72, and the discussion of L. schoutedeni in the present paper.
2. Lynchia villadce (Duges, 1887). See J. Bequaert, 1933, p. 76. Possibly a synonym of L. americana (Leach). 3. Lynchia rnacqzmtii (Rondani, 1878). See J. Bequaert, 1933, p. 78. Possibly a synonym of L. fusca (Macquart). 4. Lynchia raptatorurn (Ad. Lutz, Neiva and da Costa Lima, 1915).
See J. Bequaert, 1933, p. 82. A synonym of either L. nigra (Perty) or L. fusca (Macquart). In view of the fact that raptatorurn was said to occur in several Brazilian localities and on four species of diurnal birds of prey, I now consider that - -.
it was most probably L. n&a.
5. Lynchia penelopes Weijenbergh, 1881. This, the geno- type of Lynchia, has unfortunately not been seen by any subse- quent student. It is doubtful whether the type is still in exist- ence. Specimens should be collected again from the type host,
104 Psyche [March- June
Penelope canicollis Wagler, in northern Argentina. It is most probably a species distinct from any recognized in the present paper.
6. Ornithomyia rufiventris Bigot, 1885, Ann. Soc. Ent. France, (6), V, p. 243 (no sex; no host. Brazil: Porto Alegre). Speiser saw the type and recognized it as a Lynchia, a genus which he called Olfersia (1902, Zeitschr. Syst. Hym. Dipt., 11, p. 169). It was evidently either L. fusca (Macquart) or L. nigra (Perty) , most probably the latter.
7. Lynchia pallidilabris ( Rondani) . Olf ersia pallidilabris Rondani, 1878, Ann. Mus. Civ. Genova, XII, p. 16 1 (no sex; no host; Mexico). The size (6 to 7 mm. long) places it among the larger species. One can only surmise that it was either L. fusca or L. nigra.
