The @ has hairy porrect palpi, extending twice the length of the head beyond it. 
38. Acrolophus corvula, sp. n. 
Antennae serrate, minutely ciliate; brownish fuscous. Palpi overarching the thorax; brownish fuscous. 
Head and Thorax greyish fuscous. Forewings greyish fuscous with a slight vinous tinge, the plical 
patch takes the form of a broad very dark fuscous streak, running from near the base along the fold 
and abruptly terminated at about half the wing-length; the only discal patch is also very dark fuscous 
at the end of the cell, pointing obliquely toward the tornus and followed by a series of two or three 
semidetached anteterminal spots of the same colour; cilia pale greyish fuscous, with an indistinct shade- 
line near their base. Exp. al. 20-27 mm. Hindwings brownish fuscous ; cilia rather paler. Abdomen 
greyish fuscous: genitalia, uncus single, curved, reaching to the ends of the claspers, which are dilated 
behind the middle, tapering to an obtusely rounded apex. Legs hairy, except on the terminal joints ; 
the tarsi brownish cinereous.

The @ isa little larger than the ¢, with porrect hairy palpi extending fully twice 
the length of the head beyond it; there is some indication of single whitish scales 
thrown up between the outer end of the cell and the termen—a not unusual feature in 
the genus, but although I cannot trace these in the g I see no reason to doubt that 
these specimens belong to the same species. 
39. Acrolophus nubifer, sp. n. 
Antennae serrate; pale brownish ochreous. Palpi overarching the thorax, tufted; brownish fuscous, the 
basal joint paler in front about the level of the face. Head and Thorax brownish fuscous. Forewings 
brownish fuscous, suffused with a purplish vinous tinge, with transverse costal strigulae and a deep 
central shade of dark fuscous, the discal and plical patches being connected and rendered undistinguish- 
able in shape by the dark central suffusion, which is slightly produced towards the tornus ; cilia mottled, 
scarcely paler than the forewings. Hxp.al. 19 mm. Hindwings greyish brown ; cilia scarcely paler. 
Abdomen greyish fuscous: genitalia, uncus double at the points, evenly curved, not angulated, falling 
within the margin of the claspers which are strongly dilated posteriorly from a rather narrow stem, 
producing the appearance of a wide triangle. Legs pale brownish cinereous.
