"The larva fod on sassafi'as grew faster and lari^er than those fed on asli, and molted and 

 jinpated earlier." 



This conspieaons hairy eaterpiilar, which evidently feeds exposed on the leaves, seems to be 

 somewhat omnivorous in its tastes, and sometimes feeds on herbaeeons plants, as the burdock. 

 Hence, it apparently belon.us to the same category of hairy ]ieneiled white and black spotted and 

 tufted caterpillars, as those of Halesidota, those of the Liparida', and certain sf>ecies of Noctuidte, 

 iis riatij(Tnn-(( fitrciUa, etc. It is noteworthy as being in this resjtect exceptional among 

 Notodontians. 



Mr. Beutenmiiller has bred this species; the eggs were laid June 21, the larva entered the 

 ground August 2, pupated August 4, and the moth emerged August 27-20.

 Liiitner, Eut. Contr., iii. p. 130, 1874. (Detailed description). 



Moth (35,15 ). — The female differs from A. torrefacta in having both wings well toothed on 

 the outer edge, the apex of the fore wings much more acute, the outer margin more oblique, and 

 in having much smaller xialpi. In coloration it is quite distinct, since it does not possess the 

 prominent lines and siwts of A. torr(f(tctn. Both species have the subajjical square transparent 

 spot, but iu ^1. torrefacta it is small and inconspicuous, while a second adjoining one is wanting. 



Body and wings very uniformly pale cinereous. Head, legs, and thorax coacolorons. On the 

 inner third of the fore wings is a straight, rather broad, darker l>and, which increa.ses in width 

 toward the costa. Beyond the median broad pale gray band the wing is darker. The costal edge 

 is fuscous, the median crest of the thorax is tipped with brown, and beyond the middle of the 

 patagia is a narrow transverse line. Hind wings fuscous gray, with an indistinct .submarginal 

 line slightly waved and edged with gray. L'pper jiart of abdomen reddish. Fringe darker. 

 Beneath, the fore wings are cro!3.sed by two bands, the inner fuscous, the outer dark gray. . The 

 margin of the wings dark gray, especially the fringe. The thin broad tuft on the hind tibiie is 

 edged with brown. On each side of the base of the abdomen is a broad oblong spot, edged broadly 

 with white before and behind. 



Expanse of wings, S 43 mm.. 9 .">0 mm. : length of body, S 20 mm.. 9 22 mm. 



The species derives the name I gave it from a peculiar square transparent spot edged with, 

 brown, situated just below the apex of the fore wiugs, nearly opposite the middle point of the 

 • wing. The lower subcostal venule separates it from a much smaller adjoining one in the 

 extradiscal space.
