24. Acrolophus abdita, sp. n. 
Antennae 3 somewhat serrate toward the apex; brownish ochreous. Palpi recurved to a little beyond the 
middle of the thorax, densely hairy throughout; brownish fuscous. Thorax hairy ; brownish fuscous. 
Forewings dark brownish ochreous, with a rather tessellated pattern of dark brownish fuscous shading, 
and a single bright yellow ochreous spot immediately beyond the upper angle of the cell; the costa is 
narrowly dark brownish fuscous throughout, and, below it, the alternate dark ochreous and fuscous 
spots are perhaps more clearly defined than on the remainder of the wing-surface ; there is an indistinct 
dark brownish fuscous spot on the fold at half the wing-length, and the yellow spot at the end of the 
cell is slightly margined before and behind with dark brownish fuscous; cilia brownish fuscous, with a 
faint ochreous line along their base, a few scales above the tornus being tipped with yellowish ochreous. 
Exp. al. 18-22 mm. Hindwings paler brownish, or rather more greyish fuscous; cilia the same, with a 
pale line scarcely indicated along their base. Abdomen hairy, greyish fuscous: genitalia, uncus evenly 
curved, single; claspers of even width, rather slender, inverted at the apex. Legs greyish fuscous,

(G. C. Champion). ‘Two specimens. | 
The 2 lacks the tessellated, or mottled, pattern of the ¢, being almost unicolorous 
brownish, without the yellow spot, and the hindwings are more greyish; the abdomen 
bears a very noticeable, large, flowing tuft of curly hair-scales on the anal segments. 
Apparently allied to cleptica Wlsm., which has very similar genital segments, but 
distinguishable by its longer palpi and paler hindwings, as also by the single, pale 
yellowish spot on the forewings. 
25. Acrolophus cleptica, sp. n. 
‘Antennae serrate and shortly ciliate; brown. Palpi recurved to the front of the thorax, very hairy ; 
brownish ochreous, mixed with dark brown and some fuscous scales. Z'horaw hairy ; brownish fuscous. 
Forewings pilose at the base and somewhat roughly clothed along the costa ; brownish ochreous, thickly 
bestrewed with dark brownish fuscous scales, forming a somewhat general suffusion in which the still 
darker plical and discal patches are easily distinguished, although not clearly defined, the plical being 
preceded and followed, and the outer discal followed, by indistinct pale patches; cilia pale brownish 
fuscous, with a vinous tinge and a darker shade on their basal half. Lap, al. 18-22 mm. Hindwings 
brownish fuscous; cilia brownish cinereous. -Abdomen hairy at the base; greyish fuscous: genitalia, 
uncus single, bent over, not angulated, the claspers (apparently broken in the Type). Legs hairy; 
brownish cinereous, mixed with fuscous.
