TROPIDUCHIDB AND KINNARIDA FROM THE
BY R, G. FENNAH
Entomologist, Food-crop Pests Investigation) Windward and Leeward Islands
The material on which this paper is based was collected a few years ago by Dr. P. J. Darlington in the hilly country of Hispaniola and Puerto Rico) and is deposited in the Museum of Comparative Zoology. The two groups discussed- the Neo- tropical Paricanine Tropiduchidz and the Kinnaridz - ap- pear to have their maximum number of genera and species in the western Caribbean area and to be comparatively poorly represented in the Americas outside this region, Whether the Paricanini of the Old World form a natural group, and whether they are truly co-tribal with the Caribbean generic complex are problems which must wait for solution until the Asiatic species have been critically studied. For the time being the writer pro- poses to regard the tribe as extending to America, and lists the following characters as being common to the Neotropical genera that are assigned to it: vertex usually longer than wide, pos- terior margin deeply concave, disc depressed, ecarinate, or with median carina very prominent in the depressed area, or re- placed by a vertical plate; frons much longer than wide (1.5 to 1 or longer) with a broad longitudinal median raised band) lateral margins sinuately expanding to near fronto-clypeal suture that incurved; head in profile usually with lateral mar- gins curving evenly from vertex into frons; pronotum short) median carina prominent) disc not bounded by lateral carinq or if so bounded then narrow and strongly eminent; mesonoturn short, flattened, scarcely half as wide as long; tegmina with a nodal and an apical line of transverse veins) apex of clavus situ- ated near or basad of middle of commissural margin, subapical cells not exceeding six) apical rarely exceeding twelve; post- ' Published with the aid of a grant from the Museum of Comparative Zoology at Harvard College.

Pallid stramineous, possibly green in life, carinze of head and thorax, a stripe at sides of abdomen and a suffusion on post- femora red, sometimes concolorous, the carinze probably also piceous in some specimens; a spot on ventrolateral margin of pronotum on each side, a spot on pleurite immediately beneath the base of each tegmen piceous.
Tegmina ivory hyaline? a fuscous band from costa to anal angle just distad of basal cell, a fuscous band lying along nodal line on its distal side, and accordingly arcuately curved basad> veins of apical line of cross veins narrowly fuscous, a broad slightly paler fuscous border along apical margin, becoming paler at Cu and evanescent before apex of clavus; veins testa- ceous. Wings with apical lobe faintly suffused fuscous, R-M and M-Cu cross veins dark fuscous, veins otherwise testaceous, slightly tinged fuscous at apical margin, Ovipositor with third valvul~ each bearing eight spines on margin.
Described from two females collected at Tonala, Chiapas, Mexico (July 31, 1909) in the collection of the A. M. N. H. They agree with Spinola7s description and differ from his figures only in the slightly longer sunken disc of the vertex, the forking of Cul before the nodal line and in having one or two more apical veins. The shape of the tegmina is identical, Though this species should fall into the Tambiniine on the position of the nodal line, it undoubtedly belongs to the group of Neo- tropical Paricanine forms. AchiZo~ma fowZe~iana Kirk. is not congeneric with bicinta.

Southia differs from Paroeclidius Myers (type, P. luizi Myers, seen) in the shape of the vertex, in the length of the first seg- ment of the antenna and in the number of subapical cells; from Oeclidius Van Duzee in the lower lateral carinse of the frons, in the more prominent median carina on the clypeus, and in the less slender legs, as well as in the characters mentioned previously. In superficial appearance this insect is like Oeclidius fulgidus Van Duzee (type seen) though it lacks the pallid scutellar apex. Subfamily Prosotropinse

Described from two females taken in Maricao forest, 2,000- 3,000 ft., Puerto Rico, by P. J. Darlington (May 30-June 2, 1938). This species is distinguished by the shape of the pre- genital plate and the tegminal coloration. Quilessa pellucida sp. nov.

This species is distinguished by the genitalia and the tegminal coloration. It differs from all the lesser Antillean spe- cies in not having a lateral process projecting from the hind margin of the pygofer, a difference which may prove to be of generic value if other forms like pellucida are found with a generally similar sedeagal armature.

19451 Tropiduchidce and Kinnaridx 129
lar. Wings with four apical cell elongate-triangular with a very short basal stalk.
This genus is near Qudessa, but differs in the shape of the vertex and of the frons, in the presence of a distinct pronotal disc bounded by carinse, in the pronounced curvature of the veining at the apex in the tegmina, in the relatively more elon- gated and shorter-stalked fourth apical cell in the wings, in the wider lateral lobes of the male anal segment and in the basic form of the aedeagal armature. The four known species of this genus agree in possessing a small dark spot at the basal end of the stigma and a second dark spot in the third apical cell of M, but this character may not be of significance in identify- ing the genus.

Female. Length 2.0 mm.; tegmen, 2.7 mm.
Vertex, except carinae, base of frons, upper surface of pro- , notum except anterior margin, fuscous; carinae of vertex, basal half of frons, clypeus, thoracic pleurites, anterior margin of pro- notum, margins of mesonotum, tegulae, reddish-brown; apical portion of frons, genae below antennae, legs, valvulse of oviposi- tor, testaceous; mesonotum and scutellum fuscous-piceous with a faint greenish iridescence; abdomen piceous. Tegmina hyaline, slightly suffused yellowish-brown on clavus in basal third and apical quarter; veins and margin testaceous- fuscous. Wings hyaline, veins fuscous.
Pregenital plate quadrate, slightly more than twice as broad as long, anterior margin transverse, minutely crenulate, lateral margins in ventral view slightly diverging posteriorly, feebly convex, posterior margin transverse or very shallowly concave. Third valvulae of ovipositor broad, tapering distally to a blunt point, dorsal margin almost straight, ventro-apical margin ob- lique. First valvulae narrow, bluntly rounded distally. Described from one female taken at about 6,000 ft. at Loma Vieja, S. Constanza, Dominican Republic, by P. J. Darlington (August, 1938).

Dinepannene gen. nov.
Vertex a little longer than wide, lateral margins diverging basally, posterior margin very shallowly excavate, anterior mar- gin transverse curving uninterruptedly into frons; lateral mar- gins carinate, median carina distinct to base and passing an- teriorly into median carina of frons, no transverse carina; from longer than broad (1.4 to 11, lateral margins expanding distally not narrowing to suture, or scarcely so; greatest width of from below level of antennae; width at base slightly more than half width at apex; median carina present throughout, no median ocellus; dypeus at base scarcely as wide as widest part of from, flattened, weakly carinate medially, lateral margins carinate; vertex and basal half of from forming in profile an even curve, apical half of frons feebly convex, suture impressed; germ somewhat tumid; antennae with basal segment very short, ring- like, second segment slightly longer than broad, Pronoturn as long as vertex, posterior border shallowly excavated, sloping obliquely anteriorly near sides; median carina distinct, no lat- eral carinae on disc, lateral margins carinate between eye and tegula; mesonoturn convex, strongly tricarinate, scutellar area much depressed; posttibiz unarmed. Abdomen with wax-bear- ing plates rather prominent.
Tegmina with sides subparallel; Sc+R forking near stigma, a short Sc+R+M stem basally, nine cells on apical margin. Wings with fourth apical cell about three times as long as its basal stalk.
Genotype, Epurmene cubana Myers 1928, Studies on Cuban Insects: 20.
This genus has the wax-bearing surfaces of the abdomen de- veloped to a larger size than seems to be usual in Prosotropinae. It differs from Eparmene Fowler in having the irons reaching its greatest width below the level of the antennae, the maximum width in Eparmene being reached at the upper level of the an- tennae; in having the basal joint of the antennae very short, this being unusually long in Eparmene, and in not having a tricari- nate pronoturn. The description has been drawn up from the monotype with the original description at hand. It is worth recording that the waxy secretion of D. cubana is unusual in taking the form of curved thick parallel rods, which are trans- lucent and opalescent,
