640 HESPERIID-E. 
Indian Museum, Calcutta. The latter specimen was submitted for determi- 
nation to Mr. F. Moore, who pronounced it to be a variety of H. ladra, but I 
believe it to be a good species. 
" Expanse, <? $ , 2'1 inches. Sikkim, Khasi HiUs." [de NiceviUe, I. c.) 
Occurs at Kwei-chow, Omei-shan, Pu-tsu-fong, Moupin, and Chia-kou-ho 
in Western China ; also at Chang-yang and Kiukiang in Central China. 
Chinese specimens of this species are larger but do not differ materially 
from Sikkim specimens in Moller's collection, now in my possession, or from 
the types as figured by de NiceviUe. The subapical spots on primaries of 
male vary in number from one to three, but in the female there appear to be 
always three.

Type, benjamini, Guerin. 
" Anterior wings subtriangular, costal margin arched at base, outer margin obliquely convex, 
inner margin nearly straight. Costal nervure termiuating on costal margin nearly opposite 
end of cell ; fourth and fifth subcostal nervules emitted somewhat close together near end of 
cell ; discocellalar nervules almost subequal in length, and obliquely directed inwardly ; base 
of second median nervule about twice as far apart from that of the lower as from that of the 
upper median nervule. Posterior wings elongate, more or less lobately produced at anal 
angle. Subcostal nervules bifurcating at about one third before end of cell ; first and second 
median nervules with an apparently common origin at end of cell. Body very robust ; palpi 
broad, flattened, and coarsely pilose, apical joint long, naked and c}-liudrical ; antenna with 
the apex long, curved, and slender ; femora pilose. 
" This genus appears to be truly Oriental in distribution ; it is allied to 
Ismene, but apart from other structural characters the males have no 'glandular 
patch of raised scales' on the anterior wings, as is found in species oi Ismene." 
(Distant, I. c.) 
" Antenna; : club moderate, about as long as shaft, crescent-shaped, not bent into a hook ; very 
similar to those of Ismene, but less robust and with a longer shaft. Fore wing : no discal 
brand in male ; inner and outer margins subequal: ceU just more than two thirds the length 
of costa ; vein 12 reaching costa before end of cell ; vein 5 nearer to 6 than to 4 ; upper 
discocellular minute ; lower and middle discocellulars almost erect and in the same straight 
line, the lower the longer ; vein 3 three times as far from base of wing as from end of cell. 
Hind wing produced into a lobe ; vein 7 twice as far from 8 as from 6 ; discocellulars very 
faint, almost erect ; vein 5 ivantinj ; vein 3 from just before end of cell : vein 2 nearer to
