APOSTICTOPTERUS. — PITJIAURIA. 



631 



not quite half the length of primaries ; clubs slender, slightly curved but not hooked. Palpi 

 proiuincnt, second joint tomentosc, 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 .) 



JiJaJe. Fuliginous brown ; primaries on upper surface dusted with ochreous on basal area and tinged 



with purple in certain lights. 

 Expanse 58 raillim. 



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 PITHAUEIA.

Type, aitcMsoni, 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 Pamjjhila." {Moore, I. c.) 



Confined to the Oriental region.

 Pithauria murdavi ? , Distant, Rhop. Malay, p. 378 (1886). 



Male. Uppcrside, both wings marked precisely as in P. murdava, Moore, but all the setae on the 

 base of the wings clear whity brown, with a touch of yellow on all those in front of the sub- 

 median hervure of the fore wing, those on the interuo-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 setae 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. All the spots and streaks of both sides are no less variable in P. stramineipennis 

 than they are in P. murdava, so wo have not attempted to describe them. 

 " Female. Differs from the male in being larger, in the wings being paler, with the scanty setulose 

 clothing at their bases greyish fuscous, paler than the ground in the hind wing, and in the
