Dr. Dyar tells me that he lias found at Keeiie Valley, New York, the larva of G. avimuciila 

 or slosnoiu'fv, which is e.xactly like that of O. necem, described above. 



Subfamily II. — Apatklodin.k.' 



Head more proniiiieut than iu the previous family; antenna- well pectinated to the tips; palpi 

 large, stout, ascending, reaching well beyond the front. Fore wings triangular, falcate, and with 

 the outer edge bent in front of the middle on the si.xth subcostal venule. Hind wing's with the 

 apex unich rounded. Hind legs very thick, the femora oval. 



Larva cylindrical, almost entirely concealed by the long wool-like hair, through which arise 

 long pencilsof hairs: in niH/rlini, hairs short. Freshly hatched larva clothed with lougwhite hairs. 



The reference by Mr. Druce (JJiologia Gentr. Amer., p. 208) of this genus to the Lasiocampida" 

 seems to us to be quite erroneous, as the venation is truly Notodontian and very unlike that of 

 any of the Lasiocampidie known to us, in all of which there are four branches of the cubital vela 

 of both wings, and no bristle (frenulum) on the hind wings. The larva doe.s, however, have a 

 superficial resemblance to that of some Lasiocampa\ Let the reader compare the venation of 

 ApatelodA with that of Iclithyura and Nadata. The end of the abdomen is also tutted much as 

 in Ichthyuia. Apatelodes also spins no cocoon. Acronyctodus of Edwards is closely allied; the- 

 single species known is from Vera Cruz, Mexico.

Head moderately prominent, the front rather broad, more so than usual, subtriangular, the- 

 hairs clothing it rather uneven and loijse. Antemne in i evenly branched to the end, but' the 

 pectinations shorter than usual, about as long as the thorax. Palpi large, thick, stout, slightly 

 ascending, reaching well beyond the front, tips broad; third Joint minute, nearly concealed, not 

 distinct from second Joint. Eyes naked. 



Thorax simple, not tuftetl. Fore wings triangular; uearly one-half as broad as long; in the 

 9 much broader; costa straight, mucli curved at the apex; outer margin hcdlowcd just below the 

 apex, rendering it unusually falcate. Below the apex the outer edge of the wing is oblicpie, not 

 indented, but making an obtuse angle with the straight inner edge. Costal vein extending nearer 

 the apex than usual. First, second, and third subcostal venules suddenly detlexed upon the- 

 costa very near each other. Apical interspace broadly triangular. The fourth and fifth subcostal 

 venules of the same length; no subcostal cell. Discal area short and broad; the discal venules- 

 situate.l within the middle of the wing; the posterior di.scal venule oblique, though curvilinear. 



Hind wings large, full, and rounded on the outer margin, of an irregular pentagonal form 

 reaching nearly to the tips of the abdomen. Both discal venules very obliipie, especially the 

 hinder one. Tibia' with broad fiat concavo convex tufts. Femora densely pilo.se, giving the joint 

 an oval form; hind tibiie with dense scales, making it unusually broad, with four large spurs. 

 Abdomen of i slender, with a tuft on each side of the tip. 



Coloration, no discal spot; with gray brown transver.se lines and blotches. 



The genus is easily recognized by the broad, very falcate fore wings, their peculiar venation, 

 andby the unusually broad hind tibiaj and the large tufts at the end of the male abdomen. 



' This name was proposed by me in MS., but Neumoegen and Pyar afterwar.ls published it in 1894; the facrth^ 

 It was proposed by two different authors shows that it is well founded.
