Iiniuji). — 1 $ . Anteniuu S bipectiiiate, tilifonn on the outer third, with fine .seta? instead of 

 ve.stigial pectinations or teeth. Head and prothorax hlaclvish; front of the head rather broader 

 than usual. Tliorax gray behind, slashed with blaekish. 



Fore wings rather short and broad compared with the other species; costa straighter than in 

 A. hicolor, but not so much so as in^I. hisecta, apex .somewhat rounded, and outer edge moderately 

 convex, nearly as long as the inner edge, which is more convex than in A. hisecta. In hue 

 uniformlv iron-graj' or hoary brown, including the fringe, with no distinct lines, but a minute 

 white discal dot. with .-sometimes traces of a second or twin dot. 



Hind wings short and much rounded, not reaching so far back as in ^4. hi<x/Ioi\ more as in 

 A. hisecta, not reaching much over one-half way beyond the middle of the abdomen, which is 

 rather long. In hue dull dark pink, gray-brown on the costal and on the outer edge; inner edge 

 pink; fringe gray-brown; wings dusky pink at base. Discal spot large, round (2 to 2i mm. in 

 diameter). 



Under side of fore wings dusky in the middle, dull pinkish along the veins; an indistinct 

 extradiscal brown line; costa gray. No discal .spot. 



Hind wings gray, with a slight pinkish hue, paler toward and along the outer edge. A large 

 round black discal spot. A faint diU'use extradiscal line disappearing toward the costa and inner 

 edge. Abdomen gray, with a faint ruddy tint. 



Expan.se of the fore wings, S , 55 mm.; length of one fore wing, S , 2Smm. ; breadth of one 

 fore wing, S , li mm.; length of a hind wing, S , 21 mm.; breadth of a hind wing, S , 15 mm. 



This species may be recognized by the fore wings being unusually rounded, by the obtuse 

 apex, the hind wings being also rounded. For the venation see PI. XXXVIIl, figs. 2, 2a. 

 Another distinctive mark is the dark gray or hoary brown fore wings, with the absence of dis- 

 tinct lines. The hind wings are dull pinkish, with a large black discal spot above and beneath. 



Geographical distrihution. — Bastrop County, Tex. (Heiligbrodt fide Meske); New Mexico 

 (Streckei-). So far as known this moth is confined to central Texas and the southern portion of 

 New Mexico and Arizona. 



Arizona (Neumfegen '.). It has not yet been detected in ]\Iexico or any other part of 

 Central America. (See Map III.)
