170 Psyche ~ecember
Hulst described this beautiful geometer in 1896, regarding it as the type of a new genus, and remarking on the quite unique pattern of the wings. The type was a female collected by Bruce, with no locality stated nearer than "Colorado," This specimen
has been figured by Barnes and McDunnough, Contr. N. A. Lep., vol. 1. (1912) pi. XVI. M, morsicaria Hulst, referred by Hulst to the same genus, is now removed to Sicya, but a second Melemcea (M. virgata Taylor) was described from Arizona (Huachuca Mts.) in 1906.
On Sept. 11, 1926, I took a specimen of M. magdalena at light at Grand Lake, Colorado, alt. 8,153 ft. The species must
certainly be rare, as I had never seen it during the many years I have resided in Colorado. In the shape and pattern of the an- terior wings there is a certain suggestion of theEuropeanChesias legatella Schiff., but I presume there is no close affinity.


19261 A Species of Urocerus from Baltic Amber 169 as the first; submedian cell very little longer than the median; externomedian vein bent downward near apex, but entirely with- out any stump of a vein; second recurrent nervure entering the third cubital cell before its basal third; transverse lanceolate vein obscured at its base, but apparentJy arising just before the lower end of the tlransverse median vein. The apex of the ab- domen has been removed in polishing the amber and cannot be described.
Type in the collection of the Geologisches Institut of the University of Konigsberg
This species differs from the European U. gigas and the North American 77. albicornis, californicus and cressoni by the insertion of the first transverse cubitus on the upper side of the d'scoidal cell instead of on the basal vein. The one other North American species, U. taxodii Ashin. is not in my collection, but Bradley has published a good figure (Pomona Journ. Entom., vol. 5, p. 31) which shows the amber species to resemble taxodii in this respect. The second section of the radius is proportion- ately much longer than in any of the above-mentioned living species except U. cressoni where it is as long as the third. I have named this species in honor of Professor Klebs who first reported the occurrence of Siricidse in amber. Klebs (Tagbl. Naturforschervers., vol. 62. p. 269) in 1889 referred Baltic amber specimens to Sirex, a closely similar genus. Quite probably the present species may be the same form.
Sirex has been reported from the miocene beds of Radoboj. This was described by Heer as "Urocerites", but later referred to Paururus by Konow (Wiener Entom. Zeit., vol. 17, p. 87, 1898). The name Paururus is now replaced by Sirex. To judge from
Heer's figure the posterior tibise and their metatlarsi are flattened much as in the peculiar Cuban genus Teredon and I cannot be satisfied that Konow's reference is correct although of course the males of other genera show a tendency in this direction and Heer's specimen is probably a male; unfortunately the antennae of "Urocerites" were not preserved, so that there is no indication whether they were of the peculiar type of those of Teredon. Heer has restored them in one figure, but entirely on tlhe basis of those of Sirex and Urocerus.
