spots of the fore wing being larger, paler, and more angular ; agrees therewith in the costal 
area of the hind wing being pale brown above. 
"Expanse, J 1-8-2-0, 2 2-1 inches." (Wood-Mason, 1. c.) 
I have only one example of this species from China. It is a male agreeing 
very vpell with Sikkim specimens of the same sex, and was taken by a native 
collector at Omei-shan. 
Messrs. Wood-Mason and de Niceville in their remarks on P. straminei- 
pennis observe : — " We have long known of the existence of two species of 
the genus Pithauria occurring in almost equal profusion in Sikkim and 
Bhutan, and we recently sent a male specimen of each to Mr. Moore to be 
named in order that we might know for certain to which the term murdava 
ought properly to be applied. Mr. Moore returned the dark one (Avhich 
agrees with his figure in the Proc. Zool. Soc. Loud. 1878, pi. xlv. fig. 13) 
labelled ' P. murdava <s ,' and the light one, our P. stramineipennis, 'P. murdava 
$ .' In describing P. murdava, he does not give the sex of the typical 
specimen, but his description, like his figure, applies best to the dark form. 
Mr. Distant appears to have fallen into the same error as Mr. Moore, correctly 
figuring as the male that which we have aU along taken as the male of 
P. murdava, but describing the present species as its female. We possess 
two specimens of the female of P. murdava, which diflPer from the single one 
of P. stramineipennis in having the darker wings richly purple-glossed, with 
the very scanty setulose clothing of their bases conforming in coloiu- to that of 
the male, and in the costal area of the hind wing being concolorous with the 
rest of the organ, as in the male. Expanse 2-0 to 2-1 inches. 
" In our figure the downy clothing of the upperside of the wings at the 
base is not represented of a sufficiently light and bright shade ; it is in reality 
of a clear bright whity brown or straw-colour, which being conspicuously con- 
trasted with the dark margins, renders P. sframineipeiinis most readily distin- 
guishable from P. murdava, in which the downy clothing is, as has afready 
been stated, yellowish olivaceous. 
"The genital armature, which has been carefully examined in several 
specimens of each species, though identical in general plan, yet diff"ers greatly 
in detail in the two. 
" Some hundreds of specimens of each species have passed through our 
hands." 
Distribution. Sikkim, Bhutan, Upper Assam, Cachar, and Western China.
