LEPIDOPTERA.—ERYCINID®. $57 
The fourth family Erycrnipe (fig. 100.1. Erycina (Helicopis): 
Cupido) is distinguished by the males having only four ambulatory

feet, whilst the females have six ; or, in other words, the fore legs of 
the males are rudimental (fig. 100. 4. fore leg 3, 100. 5. ditto ? of 
Emesis Drupadi Horsf.) ; the anal edge of the hind wings is but 
slightly prominent, the discoidal cell is either open or closed, either 
entirely or partially, by a false nervure. The claws of the tarsi are 
minute, and scarcely perceptible ; the caterpillars are very short, pu- 
bescent or hairy, and the chrysalis is short and contracted ; that of 
Erycina (Helicopis) Cupido is encased in a curled-up leaf (fig. 100. 3.), 
the larva (fig. 100.2. after Stoll) having a large head, and being 
clothed with long hairs. The larva of Erygona Midas is very short and 
thick, with a large head, armed with two upright sharp horns. These 
insects, which are almost exclusively confined to South America, are 
of small size, and often of very brilliant colours; their colours are 
also often very varied, and their wings are marked with spots. Some 
of the species have the hind wings produced into two * or more tails, 
often of very great length, thus resembling the genera Papilio and 
Thecla; others in the form of their wings bear a certain resemblance 
to the Hipparchie, Heliconii, Nymphales, &c. Their flight, according to 
M. Lacordaire, is very rapid, and the majority of the species rest with 
their wings extended on the underside of leaves. M. Boisduval intro- 
duces into this family the genus Nemeobius Steph. (Pap. Lucina Zinn., 
Jig. 99. 14.; 15. head; 99. 16. palpus ; 99. 17. tip of antenna of ditto), 
an extremely interesting British species, differing in many important

tails (genera Erycina, Diorina, and Zeonia Bdv.), in Ann. Soc, Ent, France, 1837,
