LYCENID, LAMPIDES. 136 
This local race, occurring on the Andaman and Nicobar Isles, appears to be well-marked 
and easily distinguished in the male by the outer black border of the forewing being of nearly 
equal breadth throughout and not extending along the costa as it does in Indian specimens. 
The female, however, is quite similar. Mr. Distant, writing of a Malay peninsular (Province 
Wellesley) specimen, notes: “ This is a variable species, especially in the male sex, The 
male specimen here described and figured differs from the typical form of the species in the 
greater amount of melanism, or increase of the black coloration to the forewing ; whilst the 
variety zécobaricus varies contrariwise by the greater extent of the blue area. Only one male 
specimen having been collected, it will remain to be discovered whether this varietal male form 
is of a constant or local character in the Malay Peninsula, as the females are indistinguishable 
from Ceylonese examples.” Judging from a large series of specimens, the Andaman and Nicobar 
race would appear to be very constant; but this is not the case with specimens from various 
parts of India, where in some specimens of both sexes the blue area of the upperside is twice 
as extensive as it is in others, these variations being no doubt largely due to seasonal causes, the 
specimens with the greatest amount of black being found during the rains, 
The figure shows both sides of a male specimen of the local race xzcobaricus from the 
Nicobar Isles in the collection of the Indian Museum, Calcutta.

‘© FOREWING, somewhat broad, nearly triangular ; costa arched, exterior margin slightly 
oblique and convex, fosterior margin acute [sic] ; costal nervure short, curved, bent upwards to the 
costa near its end ; first subcostal nervule bent upwards and joined to the costal nervure by a 
short spur, emitted at one-half before the end of the discoidal cell, second subcostal at one-third, 
third subcostal at one-eighth before the end, fowth subcostal at one-half from the third and 
terminating at the apex, fifth subcostal [upper discoidal] from the end of the cell ; [ddle 
and lower] dtsco-cellular nervules curved, dower discoidal from their middle; discoidal cell 
broad ; third median nervule emitted at one-eighth before the end of the cell, firs# median at 
one-half before the end; sudmedian nervure straight. H1NDWING, somewhat broad, triangu- 
larly-oval, afex conyvexly-angular, exterior margin very oblique, slightly angled at the end 
of the first median nervule, and a slender Zaz/ extending from the angle ; addominal margin 
long ; costal mervure much arched at base, extending to apex ; first subcostal nervule emitted at 
one-fifth before the end of the cell ; désco-cellular nervules outwardly oblique, discoidal nervule 
from their middle ; discoidal cell broad ; third and second median nervules emitted from the end 
of the cell; fs¢ median at nearly one-half before the end ; sudmedian and internal nervures 
straight. Bopy slender, short ; fa/fi porrect, second joint projecting about half its length 
beyond the head, clothed with long adpressed scales, third joint very long, slender, naked ; /egs 
slender ; aztenn@ with a lengthened grooved pointed club; eyes hairy. Type Z. elianus, 
Fabricius.” (JZoore, 1. c.) 
In the forewing the costal nervure is very short, terminating on the margin before the 
apex of the discoidal cell ; the short spur joining the first subcostal nervule to the costal 
nervure is a feature present in /amzdes, Moore ; the base of the second subcostal is about 
half as near to the base of the first subcostal as it is to the base of the upper discoidal ; the 
third subcostal is emitted about midway between the base of the upper discoidal and the 
apex of the wing ; the disco-cellular nervules are nearly upright, slightly concave, the middle 
one rather shorter than the lower; the second median nervule emitted some distance before 
the end of the cell. In the hindwing the first subcostal nervule is emitted rather near to the 
apex of the cell, the second median nervule given off just before its lower end. Structurally this 
genus hardly differs from _/amides, Hiibner, and what differences there are are so slight that they 
can hardly be expressed ; but the style of coloration and markings will easily distinguish them. 
The transformations of two species are known. The larva is of the usual lyczenid 
shape, colour dull reddish-green, with a dorsal and a lateral darker line on each side. Pupa 
of the usual form, brown, spotted and marked with darker, .
