LYCANID.E. JAMIDES. 157 
before the end ; submedian nervure straight. H1inpwina, short, triangular, with a slender 
zazl from the end of the first median nervule 3 cos¢a/ mervure arched and extending to the apex ; 
disco-cellular nervules slightly oblique, dzscoida/ nervule from their middle ; discoidal cell short, 
broad ; second median nervule emitted before the end of the cell, fst median at nearly 
one-half before the end ; swbmedian nervure straight ; znternal nervure recurved. Bopy, 
slender, short; fa/fz porrect, second joint projecting half length beyond the head, clothed 
with adpressed scales, third joint naked, slender, about half length of the second ; /egs 
slender ; avtenn@ with a thick club ;” eyes hairy. (Moore, 1. c.) 
The costal nervure of the forewing is very short and ends on the margin considerably 
before the apex of the discoidal cell, the first subcostal nervule is of average length and is 
connected to the costal nervure by a short spur, the former is bent downwards at the point of 
union, the second subcostal arises quite close to the base of the first, the upper discoidal arises 
from the subcostal nervure quite three times as far from the base of the second sub- 
costal as the latter does from the base of the first, the third subcostal arises about midway 
between the apex of the wing and the base of the upper discoidal ; upper disco-cellular slightly 
outwardly oblique, lower disco-cellular upright, distinctly longer than the upper. I can find no 
structural character of sufficient importance to put into words by which this genus can be 
separated from the next. On this subject Mr. Doherty writes ‘‘ I am not aware of any difference 
between Jamides and Lampides, and think it likely that the former genus will have to fall 
before the latter, which occurs earlier in Hiibner.’’ 
The genus Jamzdes contains I believe but a single species. It has a very wide range, 
occurring in India on the lower slopes of the outer ranges of the Himalayas, throughout conti- 
nental and peninsular India except the dry North-West, in Assam, Burma, the Malay Peninsula 
and Archipelago, Ceylon, the Andaman and Nicobar Isles, in China, and in Australia. The 
male on the upperside of the hindwing and on the basal area of the forewing is most resplendent 
shining metallic steely-blue or purple, the costa, apex and outer margin of the forewing widely 
black, hindwing with a narrow black outer margin. Underside castaneous-brownish, crossed by 
narrow fine whitish lines, a large black spot surrounded by orange at the base of the tail. 
The female on the upperside has no metallic lustre, but is dull blue, with a series of bluish 
lunules on the hindwing along the rather broad outer black border. The transformations of 
the species are unknown, but Mr. E, E. Green informs me that in Ceylon he has observed the 
female butterfly laying eggs upon the pods of various Leguminosae.
