OOSPILA. By L. B. Prottt.

0. fenestrata Bastelb. (7 a), described as a Progcnode.s, probably belongs here, but has lost its hindlegs, fenestrata. 
It seems only to differ from lacteguttata (6 h) in the absence of the cell-spot of the forewing. E. Peru: Oxa- 
bamba, 1 
0. thalassina Warr. (6 h). Rather more bluish green, with some dark maculation at distal margins, tlwlassina. 
the hindwing with two cell-dots, as in several Oospila, a raised white one on the 2nd discocellular, a black, red- 
edged one on the 3rd. Peru: Cuzco (type) and Carabaya. 
0. (?) peralta & chaus (8 a), only known to me from a figure of the G type (here copied), is said to be prratta. 
near R.restricta Warr. (7 a), but seems likely to be near 0. lacteguttata, possibly even a small form of it. 26 mm. 
In addition to the cell-dots and white terminal spots (which extend on to the brown, white-tipped fringes), it 
shows traces of a dark postmedian shade and on the forewing of an antemedian. Peralta, Costa Rica. 
24. Genus: Oospila Warr. 
Palpus moderate to long, terminal joint in the $ strongly elongate. Antenna in the $ generally pectinate. 
Hindtibia with terminal spurs only, that of the $ sometimes fringed with long hair. Abdominal crests strong. 
Forewing with 1st subcostal from cell, 1st radial usually stalked, 1st median often stalked. Hindwing generally 
with a raised white spot on the 2nd discocellular; 1st median generally well stalked. A rather extensive South 
American genus, to which has been added one species from North America. 
0. lesteraria Grossb. is unknown to me. It is said to be much like Eueana niveociliaria (8k). Pale apple lesteraria. 
green, the markings white or cream-colour; antemedian of fore wing widening posteriorly and here preceded 
by some maculation; base of hindwing white; postmedian of both wings followed by maculation between the 
radials and at hind angle. No cell-dots. Arizona. 
0. confundaria Mbschl., founded on 2 $$ from Porto Rico, belongs here, though its author calls the confun- 
red markings on the abdomen “spots”, not “crests”. “18 mm”. Green, without lines, the forewing sometimes 
with a dark cell-dot; a reddish terminal line, interrupted with white at the veins, at hind angle sometimes 
widening a little into a small white-dotted spot; fringes spotted with red. A similar — perhaps identical — Oospila 
occurs on Sta. Lucia and Dominica, possibly a form of the following. 
0. coerulea Warr. (6 h). Easily known by the long-fringed hindtibia of the <$, the non-pectinate antenna coerulea. 
of the $ and the simple pattern. Described from French Guiana, but distributed to Venezuela and the Amazon. 
— aphenges subsp. nov. is slightly less bluish green, the terminal line very slight, sometimes almost obsolete, aphenges. 
especially posteriorly, its colour less purplish; fringe paler, less strongly mixed with pink. Matto Grosso, the 
type $ from Urucum, 15 miles S. of Corumba, 650 feet, 16—23 November 1927 (C. L. Collenette) in coll. 
Joicey, which contains a second $ from Burity, 2250 feet, from the same collector. Aslo known from Tutaya, 
E. Brazil (Mus. Tring) and Recife, Pernambuco (H. Zerny, Mus. Wien) and I think from Sapucay, Paraguay. 
0. derasa Warr. (6 h). Distinguished by the large spot at tornus of forewing, usually also a small one derasa. 
at that of hindwing. Occasional transitions strongly suggest that it is a form of coerulea. French Guiana (loc. 
typ.) and the Amazons. Mr. Collenette took in Matto Grosso (Tombador and Burity) a form with reduced 
tornal spot which, if the above suggestion is correct, might be called coerulea aphenges ab. derasa. 
0. sesquiplaga Prout is similar to derasa (6 h) with rather larger posterior blotches and on the forewing sesqui- 
an additional terminal mark between the radials, pyramidal in form. “Brazil” (ex coll. Satjnders), founded on plaga. 
a $ in the Oxford Museum. I assume that the $ will prove to have the hindtibia fringed as in coerulea. 
0. sellifera Warr. (6 h) belongs to the same structure group as coerulea, but is very distinct in the ample sellifera. 
purple borders. Both wings with a small black cell-dot on the 3rd discocellular ; the raised white dot on the 
2nd discocellular of the hindwing sometimes slight. Guianas and Amazons, described from French Guiana. 
0. lilacina Warr. (7 c) is larger than sellifera, with the borders more extended, especially at the hind- Marina. 
margins, and mixed with whitish; hindwing with 2 white cell-spots. & hindtibia strongly fringed. I do not 
know the $. French Guiana. 
0. longipalpis Warr. recalls sellifera (6 h) in its coloration but is larger, especially in the $, which expands longipalpis. 
46 mm. Distinct in the subfalcate fore wing and in the shape of the dark borders; that of the forewing is less 
broad and with only a shallow proximal sinus; that of the hindwing, on the other hand, broader (except at 
the apex) and without the deep excavation behind the radial fold. Beneath, the dark border of the forewing 
is reproduced, that of the hindwing becomes subterminal. <§ hindtibia strongly fringed. $ palpus very long, 
her antenna not described. French Guiana, very rare.
