 Pithauriopsis, Wood-Mason & de Niceville, Jour. As. Soc. Beng. 1886, p. 387 ; Watson, 1. c. 

 Type aitchisoni, Wood-Mason & de Nic^v. 



Fore wing rather narrow and pointed ; thorax very stout ; abdomen conical, not longer 

 than the dorsum of the hind wing. Autennee about half as long as costa ; club slender ; 

 apiculus acicular, reflexed, at least one-half as long as the club. Palpi appressed, 

 densely scaled, third joint almost concealed. Fore wing : no hyaline spot in cell 4, 

 vein 2 arising near the half-length of the cell, vein 5 nearer 4 than 6. Hind wino- : 

 cell less than half as long as the wing, angulated at the origin of vein 7 and also at the 

 origin of vein 2, vein 5 absent ; termen feebly curved, nearly straight between veins 1 a 

 and 7 ; tornus not distinctly produced. Epiphysis present ; hind tibiae with two pairs of 

 spurs. Front coxse in the male densely clothed with locg hair-like scales, and in the 

 same sex the disc of the hind wing above is densely clothed with long hair-like scales. 



There are three species separable as follows : — 



Males. 

 1 (4) . No sex -mark on the fore wing above. 

 2(3). The long clothing of hind wing above not conspicuously pale, murdava, Moore. 



3 (2) . The long clothing of hind wing above whitish grey . . . stramineipennis, de Niciiv. 



4 (1). A double sex-mark near the middle of cell 1 a on fore wing 



above, precisely similar to that found in the genus Halpe. aitchisoni, W.-M. & de Nicev. 



! PiTHAUKIA MURDAVA. 



Ismene murdava, Moore, P. Z. S. 1865, p. 784. 



Pithauria murdava, Moore, P. Z. S. 1878, p. 689, pi. xlv. fig. 13 ; Distant, Rhop. Mai. p. 378, 

 pi. XXXV. fig. 9, 6 (1886) ; Watson, Hesp. Ind. p. 27 (1891). 



The female of this species has ou the hind wing below a suffused subterminal pale 

 band, and an oblong pale spot in each of cells 6 and 7, being thus distinguished 

 from the female of P. stramineipennis, in which the hind wing below is uniform grey by 

 reason of a sprinkling of whitish-grey scales on a pale greenish-brown ground ; in one 

 of my two specimens of the latter there is a feeble pale spot near the basal third of 

 cell 6 on the hind wing below.
