APOSTICTOPTERUS. — PITIIAURIA. 631 
not quite half the length of primaries ; clubs slender, slightly curved but not hooked. Palpi 
prominent, second joint tomentose, third joint nearly as long as the second, densely clothed 
with long scales which project beyond the tip. Thorax and body slender, the latter extending 
beyond the anal angle. Head almost as wide as the thorax. 
ApOStictopteruS fuliginosUS, sp. nov. (Plate XXXVIII. fig. 8, d .) 
Male. Fuliginous brown ; primaries on upper surface dusted with ochreous on basal area and tinged 
with purple in certain lights. 
Expanse 58 millim. 
Occurs in Western China, whence I received one specimen which was taken 
in July at Omei-shan. 
This species bears a superficial resemblance to Astictopterus diodes, Moore, 
but it is altogether a more slender insect. 
Genus PITHAURIA.

Type, aitchisoni, W.-M. & de N. 
" Fore wing elongated, narrow ; apex pointed ; exterior margin very oblique ; hind margin short ; 
hind wing convex externally, lobular at anal angle. Head and thorax very broad, robust ; 
abdomen not so long as hind wing. Antennae with a slender club and very long, whip-like 
tip. Venation similar to Pamphila." {Moore, I. c.) 
Confined to the Oriental region.

Pithauria murdavi ? , Distant, Rhop. Malay, p. 378 (1886). 
■' Male. Upperside, both wings marked precisely as in P. murdava, Moore, but all the seta? on the 
base of the wings clear whity brown, with a touch of yellow on all those in front of the sub- 
median neiTure of the fore wing, those on the interno-median area of this wing being con- 
colorous with the whity-brown down of the hind wing, the costal area of which is above 
more or less extensively pale brown. In P. murdava the set® in the hind wing are yellowish 
olivaceous, all those of the fore wing distinctly yellower ; and the costal area of the hind wing 
is dark. AU the spots and streaks of both sides are no less variable in P. stramineipennig 
than they are in P. murdava, so we have not attempted to describe them. 
" Female. Differs from the male in being larger, in the wings being paler, with the scanty setuloso 
clothing at their bases greyish fuscous, paler than the ground in the hind wing, and in the
