100 MEMOIRS OF THE NATIONAL ACADEMY OF SCIEI^CES. 



The genus may be also distinguished by the short autennal pectinations; by the large palpi; 

 by the simple, untufted -thorax; by the falcate fore wings, the outer edge not scalloped, and by 

 the broad concavo-convex tibial tufts. 



The generic name was suggested by the resemblance of the hairy larva to Apateht anicricana. 

 Our species can not be referred to the same genus as rurnthyrh cedo-miUi of Cramer, at least 

 until we have examples of that South American form for comparison. 



E(ig. — Very much flattened, resembling a very shallow inverted plate, with sloping sides, 

 the surface appearing as if ringed, each ring inclosing a circle of 5 to 7 spines. 



Larva. — Body cylindrical, nearly smooth, almost completely covered by long, fine, dense hairs, 

 through which are seen on each side the lateral row of black spots; most of the hairs dark on 

 the distal half, jjale at base, and from the black (hu'sal spots arise from Ufo to four spindle-sha]>e(l 

 black hairs forming median dorsal pencils on the abdominal segments. A long, slender median 

 pencil arises from the second and third thoracic segment, and a single median pencil is directed 

 backward, arising from the eighth abdominal segment. Freshly hatched larva, smooth-bodied, 

 thickly covered with long white hairs, arising from small tubercles.

Geographical (listrihution. — Tlie species range from Xew England and Canada southward to 

 Florida and Georgia, and appear to exist in Surinam and Brazil. The genus is well represented 

 in Central America; three species, according to Druce, occurring in Mexico, one, A. adrastria 

 Druce, near A. torrefacta, recorded from Cordova, Mexico, Yucatan, Costa Eica, and Panama; 

 A. ardeola Druce occurs in Panama and also on the Amazons, while another inhabits Guatemala.

Moth (53,22 ). — Soft velvety ashen. Palpi and hind margin of the thorax reddish brown. 

 Fore wings with a large reddish brown spot on the base of the internal margin; no discal spots; 

 beyond is a line of the same color which crosses the wings and is curved inward on the costa. 

 An outer, nearly straight, slightly liexuous, very faint line. Just beyoiul the middle of the wing is 

 a similar but more distinct line. A wavy submarginal line, curved outward just before reaching 

 the costa. A minute subapical white spot margined externally with reddish brown. Hind wings 

 tinged with reddish. A light median obsolete line terminates on the intei'nal margin in a white 

 spot, which above and below is reddish brown. Fore wings a little paler beneath; the subapical
