" Allied to Virachola. "Wings small. 
"■Fore whirf comparatively shorter and less acutely triangular in form ; exterior margin slightly 
convex ; furnished with a broad tuft of hair on middle of posterior margin beneath. 
" Hind tviiitj less produced hindward, more convex exteriorly ; anal angle lobed ; a single tail from 
end of lower median vein ; male with a broad conical-shaped glandular depression between 
the costal and subcostal veins, but which does not extend below the subcostal. 
" Palpi shorter, second joint more laxly squamose. 
" Type li. varima." (Jloore, I. c.)

" Male. Upperside : both wings shining bluish purple or deep steel-blue, variable in shape. Fore 
wing with the costa, apex, and outer margin purplish black, sometimes without any other 
marks, sometimes with a small orange patch beyond the cell, sometimes with a patch nearly 
as large as in Hysudra selira, Moore. Hind wing with the costal margin pale, the abdominal 
margin fuscous, the anal lobe black, with a patch of ferruginous scales near the middle. Under- 
side : both wings with the ground-colour somewhat variable in tone, sometimes pale brown, 
sometimes ochreous brown. Fore wing with two fine dark lines defining the discocellular 
nervules ; a very straight, even, decreasing diseal band from the costa almost to the submedian 
nervure, outwardly finely defined with white ; an obscure submarginal fascia. Hind wing 
with similar markings, but the diseal band recurved to the abdominal margin, where it is 
defined on both sides with white ; anal lobe black, submedian interspace on the margin also 
black, but heavily sprinkled with whitish scales, a black spot crowned with orano-e in the 
first median interspace. 
" Female. Upperside : both wings rather duUor in shade, otherwise similar to the male." {dc Nice- 
ville, I. c.) 
"A variable species. The male is sometimes, as in Kollar's figure, without the red spot on the 
middle of the anterior wing, sometimes it is more distinctly marked than in the fio-ure 42 of 
the plate. In colour it dift'ers from other allied species, and, like the females of varuna, 
Horsfield, scndi iilieretina, Hewitson, is of a dull grey- or indigo-blue. On the underside the 
transverse band is far apart where the wings meet." {Hewitson, I. c.) 
The first specimens of this species which I received from China I considered 
to be distinct from any described Rapala ; but now that I have a larger amount 
of material, in the shape of specimens both from India and China, I find that 
my suhpurimrea is not specifically separable from B. nissa.
