"The larva fed on sassafras grew faster and larger than those fed on ash, and molted and 

 pupated earlier." 



This consi)ienous hairy caterpillar, whicli evidently feeds exposed on the leaves, seems to be 

 «oniewhat omnivorous in its tastes, and sometimes feeds on herbaceous plants, as the burdock. 

 Hence, it apparently beloni^s to the same category of hairy penciled white and black spotted and 

 tufted caterpillars, as tiiose of Ilalesidota. those of the Liparida/, and certain species of Noctuid;e, 

 as Platyceruro fiirciUa, etc. It is noteworthy as being in this respect exceptional among 

 NotodontiaTis. 



Mr. Beutenmiiller has bred tliis species; the eggs were laid .luiie 114, the larva entered the 

 ground August 2, pupated August 4, and the moth emerged August 27-l!9.

Lintnei; Eut. Contr., iii, ]>. 130. 1874. (Detailed description). 



Moth (3 (? , 1 5 ).— The female differs from A. torrrfacta 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 palpi. In coloration it is quite distinct, since it does not possess the 

 prominent lines aud spots of A. torrcfacta. Both .species have the subapical square transparent 

 spot, but in A. torrefacta it is small and inconspicuous, while a second adjoining one is wanting. 



Body and wings very uniformly pale cinereous. Head, legs, and thorax coucolorous. t)n the 

 inner third of the fore wings is a straight, rather broad, darker band, which increases 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. Upper part of al)domen reddish. Fringe darker. 

 Beneath, the fore wings are crossed 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 tibia:' is 

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

 with white before aud behind. 



Expanse of wings, $ 43 mm., 9 .jO mm. ; length of body, $ 20 mm., 5 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 wings, nearly opposite the middle point of the 

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

 extradiscal space.
