LEPIDOPTERA INJDICA . 
one common ancestor and have now developed into easily distinguishable races in the 
various localities they inhabit. Unfortunately Colonel C. T. Bingham in the Fauna of 
British India has to a great extent followed Captain Watson, but he does discriminate 
certain groups and races, and we agree with Dr. Butler that if a thing is distinct it 
ought not to have the same name as that from which it is admitted to be distinct, 
because otherwise, every time it is referred to, it would have to be described, and it 
is so much more simple and convenient to refer to it by its recognised name. 
Imago. —Wings ample, broad. Forewing short, sub-triangular; costa much 
arched from the base, exterior margin slightly uneven and almost erect; costal vein 
extending to two-thirds of the margin; first sub-costal branch emitted at one-third, 
and second at one-eighth before end of the cell, third trifid, the fifth from beyond end 
of the cell ; the cell very broad and extending to fully half the wing ; discocellular 
veinlets outwardly oblique, both concave, upper shortest, the radial emitted from their 
angle ; middle median veinlet emitted at one-sixth, and lower at one-third before end 
of the cell; sub-median vein much recurved. Hindwing obconical, short; exterior 
margin oblique, uneven, slightly angular before its lower end; pre-costal vein slender; 
costal vein curved towards the end; first sub-costal emitted at one-fourth before end 
of the cell and much curved; discocellulars very oblique, upper shortest, lower 
recurved, radial from their angle ; cell broad ; middle median branch curved, emitted 
at one-sixth, and lower at one-third before end of the cell; submedian vein slightly 
curved ; internal vein recurved. Body stout; thorax and head hairy ; palpi projecting 
slightly beyond the head, hairy beneath, third joint short; legs slender; antennae 
terminating in a gradually compressed club. 
Larva. —August 8th, 1864. Wangtoo, N.W. Himalaya. Food plant Capparis 
obovata. Head small, second, third and fourth segments largest; other segments 
diminishing to twelfth, which is smallest, thus giving a tapering form. Colour 
uniform pale transparent yellowish-green. On each of fourth to eleventh segments 
are eight small inconspicuous reddish spots, which are disposed on each segment above 
the legs ; legs and prolegs pale green. A considerable number of various ages and 
sizes were feeding together on a branch of Capparis ; one or two bushes were 
eaten almost bare of leaves. A few empty pupse were on the twigs, and also in 
the crevices of the rocks on which grew the bushes. The largest larvae were 
l T 2 o inches in length, and one of these, on capture, began to spin up for pupa. 
Pupa. —August 10th. Boat-shaped; very much arched and very pointed, 
especially at the anterior extremity, which is produced into a sinuous snout. Colour 
pale ochreous-yellow, indistinctly very faintly speckled; a dark narrow stripe down 
the back, which is slightly keeled along this stripe ; a faint stripe along each side 
from the posterior extremity up to the wings; segments movable. 
Imago emerged on August 25th a female of Pyrene (Captain A. M. Lang, ms. Notes). 
Type, Pyrene.
