nearly 60 mm. Egg and Caterpillar at birth: Unknown. Mature 

 Caterpillar : Black, the front of the first thoracic segment, the pro- 

 legs, and the base of many of the spines more or less ochraceous. 

 Feeds on Lippia. Chrysalis : Smooth and wholly black, except that 

 the borders of the antennal cases and the stigmatal fissures are whit- 

 ish, and the cremaster is somewhat ochraceous at base. — Texas,

Tribe EPICALINII. 



Butterfly: Antennae exceedingly slender, the club slender, nearly 

 always elongate and then very gradually incrassate, feebly unicari- 

 nate beneath, the carination concealed when the club is elongate 

 by the infolding of the under surface. Palpi compact, tapering, 

 subcompressed and rather elongate, the last joint moderately long. 

 Wings simple, usually broad, the hind wings well rounded, entire 

 or feebly crenulate; cell of hind wings open, of fore wings open or 

 closed by a feeble sinuate vein. Last tarsal joint with two rows 

 of spines beneath. Egg: Short, subcorneal, provided with few 

 (10-11) not very prominent ribs which increase very slightly in 

 height toward without reaching the pole. Caterpillar at birth : 

 Head simple, subtriangular. Trichomes of body bristle-like, very 

 short and apically knobbed, arranged in five longitudinal series on 

 each side, three above the spiracles. Mature Caterpillar : Head 

 subquadrate, supporting a pair of excessively long, widely di- 

 verging subequal horns, armed with more or less whorled spine- 

 lets. Body armed with long, ranged, corneous, sparsely aculiferous 

 spines, occasionally furnished with one or two spinelets, and always 

 crowned by an independent needle, some of the spines occasionally 

 reduced to warts; there are a dorsal series, and two other pairs above 

 the spiracles, all the developed spines of nearly the same length. 

 Feeds on Sapindacea?, Euphorbiacece, and Urticacese. Chrysalis : 

 Smooth, somewhat depressed, especially on abdomen, which tapers 

 rapidly and has no ridges; a slight mesothoracic carina, sometimes 

 produced to a point, prominent wing tubercles and short conical 

 frontal tubercles ; cremaster broad. 



SYNOPSIS OF OUR GENERA. 



Eunica. Butterfly : Two superior subcostal nervules arising in the fore wings 

 before the end of the cell, which is closed; costal and median veins much 

 swollen at the base. Mature Caterpillar: Coronal horns of head with a very few 

 opposed spinelets. Body subcylindrical.
