The ¢ is in very poor condition; the ?, which is a little better, is freely irrorated 
with rather dark fawn-brown strigulae, a small pointed patch of the same crossing the 
fold downward beyond its middle, and almost connected upward with a similar spot at 
the end of the cell—placed obliquely a little beyond it; the subapical area is less 
freckled than the remainder of the wing-surface, and the hindwings have a distinctly 
darker and more fuscous tinge than the forewings; aJl the veins are separate in both 
wings. The uncus of the ¢ is double, angulate, the angle at the bend not produced ; 
the claspers are wide and rather deeply excised at their apex, the upper angle slightly 
produced, inverted, and truncate (WIsm. MS. &05/1904). 
7. Acrolophus cosmeta, sp. n. (Tab. X. fig. 28.) | 
Antennae subochreous, the basal joint pale testaceous. Palpe closely appressed to the face, the terminal 
joint erect, longer than the median, both densely hairy ; pale testaceous, the median joint shaded with 
dark brown externally. Head and Thorax pale testaceous. Forewings somewhat shining, pale 
testaceous, a dark fuscous streak along the base of the costa, an outwardly oblique, uncate, cuneiform 
fawn-brown blotch before the middle of the dorsum, with a separate dorsal spot of the same colour 
beneath its apex; about the wing-surface are numerous specklings of pale fawn-colour, especially along, 
beyond, and above the cell; cilia pale fawn, with some dark brown scales along the margin at their base 
around the apex and upper half of the termen. Exp. al. 24mm. Hindwings whitish cinereous, shaded 
with greyish brown on their outer third; cilia somewhat dense on the outer half of the costa, whitish 
cinereous shading to brownish grey on their outer half. Abdomen brownish grey. Legs whitish 
cinereous.

8. Acrolophus arida, sp. n. 
Antennae simple; pale brownish cinereous. Palpi short, porrect, reaching nearly the length of the head 
beyond it; very hairy, the short terminal joint almost concealed; brownish cinereous. Head and 
Thorax pale brownish cinereous. Forewings with rather rounded costa, depressed apex, straight oblique 
termen and somewhat angular tornus, the dorsum rounded and widened; whitish ochreous, sparscly 
mottled and streaked with fawn-brown, with some admixture of blackish scales—these especially 
noticeable in an elongate patch along the base of the costa, in a series of seven or eight costal spots 
from middle to apex, and in lines following the neuration about the lower angle of the cell and beyond 
the end of the cell to the termen and apex; cilia whitish ochreous, mixed with fawn-brownish. 
Exp. al. 23mm. Hindwings rather shining, pale brownish grey ; cilia whitish cinereous, with a double 
fawn-brown shade-line running through them. Abdomen brownish grey, with paler transverse bands 
Legs whitish cinereous (broken). ;
