NYMPHALID^. 
at equal distances apart from the second and the tip of the wing. Upper discocellular 
vein very short, straight, arising at about half the length of the wing; middle discocellular 
much longer, directed towards the base of the wing, its tip curved a little outwards ; the 
lower discocellular still longer, and continuous with the tip of the middle one, oblique, 
directed outwards, and uniting with tlie third branch of the median vein at about the same 
length from its origin as the length of the outer discocellular itself, and rather shorter 
than the space between the first and second branches of the median vein. 
"Hind ivings triangularly ovate, hairy; fringe long. Outer margin very convex and entire. 
Inner margin generally emarginate towards the extremity. Costal vein not extending half 
the length of the costa. Fostcostal vein arising much nearer the body than the precostal, 
branching at a considerable distance from its base. Upper discocellular arising at a short 
distance from the base of the branch, curved ; outer discocellular considerably longer, 
oblique ; uniting with the third branch of the median vein at a distance from its origin about 
equal to two thirds of the space between the first and second branches of the median vein ; 
closing the discoidal cell in a rather acute point near the middle of the wing. 
" Fore legs of the male small, very densely hairy. Femur and tibia of nearly equal length. 
Tarsus not quite half the length of the tibia, simple. Fore legs of the female longer than 
those of the male, very slender. Tibia longer than the femur, moderately hairy. The tarsus 
equal in length to the tibia, very slender, articulated, not dilated at the tip ; the joints with 
very minute spines at the extremities beneath. Ungues wanting. 
" Four hind legs moderately long, scaly. Femur slightly clothed beneath with hairs. Tibice 
armed beneath at the sides with moderately long and acute bristles ; tibial spurs long. 
Tarsus long, armed beneath and at the sides with rather long bristly hairs. Ungues acute, 
curved, entire. 
" Abdomen moderately long and slender." (Westwood, I. c.)

Var. annulifer, 15utl. " Nearly allied to C. geticus, but larger, longer in the wing, much darker ; 
on the underside with the plumbagiiieous streak, which bounds tho ocelli of secondaries 
internally, straight on its inner edge instead of undulated. Expanse of wings, cJ 1 inch 
7 lines, $ 1 inch 10 lines.— About .'570 miles from Tokci." (Butler, I. c). 
My specimens of C. oedipus from Japan arc not specifically separable from 
European examples. In Europe the species varies in size, and the lustrous 
streak of under surface is also subject to variation, sometimes assumin<2j the 
character of a broad abbreviated fascia and as often straight as undulated. 
Dr. Henry C. Lang (' Butterflies of Europe,' p. o04) says tliat tlie larva 
is green, with a darker dorsal stripe and pale yellow lateral line, and that it 
feeds on Carex in July and August.
