no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 145 



Fore wings much more falcate than usual, the great elongation of the apex being carried 

 to an excess in Holocera; the apex itself is obtuse, roundish; the outer edge is below the apex 

 deeply excavated; the inner angle is somewhat rounded. 



Hind wings short, distinctly triangular; the costal edge unusually convex; the apex much 

 rounded; outer edge deeply excavated especially in Holocera; abdomen not reaching beyond 

 the hind wings. 



Venation: Vein III 2 in wings of both pairs being entirely independent, as in Hylesia, the 

 discal veins taken together forming a line directed a little inward, or especially in the fore wings 

 of Holocera still more so and situated quite far out beyond the middle of the wing, so that the 

 veins beyond III 2 , III 3 , IV, are very short. In the hind wings the vein III 2 forms an independ- 

 ent vein; the discal veins taken together forming a line either bent or curved outward. Vein 

 II, always wanting. 



Legs long, slender, hairy, vestiture not dense and closely cropped, but sparingly hairy, 

 the hairs inclined to form a lateral fringe on the tibiae and tarsi. The fore tibial epiphysis is 

 large, long and sack-like, nearly two-thirds as long as the long, slender tibias (Holocera). 



Genitalia exhibit no distinctive subfamily characters, but are quite closely related to those 

 of Anisota as regards the suranal plate (especially A. virginiensis) , which ends in two black 

 chitinous lobes, in the form of the claspers, of which there is but a single pair, and in the penis 

 and triangular upper plate.

SYNOPSIS OF THE GENERA. 1 



Fore wings moderately falcate; apex obtusely pointed; large ocelli on hind wings Henucha. 



Fore wings remarkably falcate, costal edge concave; apex squarish, no ocelli on hind wings Holocera. 



[A penciled note adds:] Ludia is a synonym of Henucha. [But in the fuller treatment beyond they are kept separate.]

Imago. — ■ <? . Head in front subtriangular, not very narrow, moderately broad ; eyes 

 rather large. Antennas broadly pectinated at base, subfiliform or serrate on the outer third; 

 in ? nearly filiform; less widely pectinated than in Ludia or Sagana. The antennae are described 

 from Felder's figure, being lost in my male- 

 Palpi not distinct, the hairs loose and not distinguishable from those of the front, the 

 palpi not being long enough to reach the front. 



Fore wings long and narrow, excessively produced, the apex being long drawn out, much 

 more so than in Ludia, the costa much arched toward the apex; the outer edge deeply exca- 

 vated; in 9 the wing is much broader, the apex wider but more pointed, and the outer edge 

 is but slightly excavated. Hind wings triangular, rounded on the apex, somewhat produced 

 at the inner angle, reaching as far as the end of the abdomen; in ? also a little produced and 

 reaching to the tip of the abdomen. 



Venation: Near that of Ludia, vein II, as in Ludia, no vein II 2 , but differing in the follow- 

 ing respects: The origin of vein III, is close to that of the anterior discal vein, the latter arising 

 inside of it, not some distance beyond the origin of III,, as in Ludia; the posterior discal vein 

 is curved inward; in the hind wings the veins given off from the outer side of the discal cell are 

 longer, their origin nearer the middle of the wing. 



1 [The genus Carnegia Holland (Entom. News, 1896, p. 134), from the Cameroons, looks like an extreme development of the Holocerine type, 

 with a wing form rather approaching that of the neotropical Tcratopteris. I have examined the type of Carnegia mirabilis Holl., in Dr. Holland's 

 collection. It is a very distinct and remarkable form; the antemedian band is of quite a different form from that of Holocera; wings of both pairs 

 multifenestrate; apex of primaries strongly falcate; anal angle of secondaries strongly produced; postmedian band of primaries strongly scalloped. 

 The thorax is wholly without the broad light collar of related genera. The venation is figured by Holland (1. c), as also the pupa. Strand (1910) 

 has described a second member of the genus, C. geniculipennis.]
