which is bluntly subfaleate; hind margin bulged below 
middle, indented below apex, and oblique above anal angle ; 
anal angle well marked. Hind wings with apex falcate ; 
anal angle strongly marked, hind margin bulged in centre ; 
the fore wings have an oval scaleless patch at the base of the 
cell between the first and second median nervules, and the 
spaces between the second and third and the third and the 
lower radial are also partially semitransparent; the hind 
wings have prominent tufts of hair along vein 2 on the upper- 
side. These peculiarities are to be found in both sexes. 
Palpi porrect, rostriform ; antenne long, two thirds of fore 
wings, filiform, ciliated in male. Neuration normal. 
Type Discothyris ferruginata, Moore (Agrotera). 
vestigialis, Snell. (Gonocausta?), Tr. E. 8. 1890, p. 628, 
also belongs here. 
Genus Cavirrons, Zell. 
Cavifrons simplea, sp. n. 
Wings very pale straw-colour, glossy ; fringes concolorous ; 
head and thorax whitish ; abdomen probably the same, but 
greased. Underside of hind wings like upperside; of fore 
wings suffused with cinereous along the middle, the costa 
remaining straw-colour, and the inner margin pure white. 
Expanse of wings 28 millim. 
One male from Larima County, Colorado. 
Of the same size as, but rather paler than, Cavifrons biun- 
dulalis, Zell., from which it is distinguished by the entire 
absence of markings; the palpi are shorter than in the type 
species. 
Genus SPILODES, Guen. 
Spilodes fraudulentalis, sp. n. 
Fore wings pinkish fawn-colour, without markings, except 
a broadish pale yellow fascia parallel to hind margin at two 
thirds, not reaching the costa; fringes dull yellowish. Hind 
wings the same, but the fascia approaching the margin 
towards anal angle and curved and somewhat diffuse. Head, 
thorax, and abdomen concolorous. Underside like upper ; 
the legs pearly white. 
Expanse of wings 32 millim. 
Several males from the Khasias. 
This species mimics Moore’s flavofasctata, but the ground- 
colour of the wings is not so dark and the yellow fascia 
straighter.
