MEMOIRS OF THE jS^ATIOXAL ACADEMY OF SCIENCES. 
The geuus may be also distinguished by the short antennal pectinations; by the large palpi; 
by the simple, untufted thorax; by the falcate fore wiugs, 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 Apatela americana. 
Our species can not be referred to the same genus as Parathyrin cedo-nuUi of Cramer, at least 
until we have examples of that Soutli American form for comparison. 
— 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, pale at base, and from the black dorsal spots arise from two to four spindle-shaped 
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 distribution , — The species range from New 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 Rica, and Panama; 
A, ardeola Druce occurs in Panama and also on the Amazons, while another inhabits Guatemala.

Moth (55,2? ). — Soft A^elvety ashen. Palpi and hind margin of the thorax reddish brown. 
Fore wings Avith a large reddish brown spot on the base of the internal margin; no discal spots; 
beyond is a line of the same color Avhich crosses the wings and is curved inward on the costa. 
An outer, nearly straight, slightly flexuous, very faint line. Ju.^t beyond the middle of the wing is 
a similar but more distinct line. A wavy submai‘ginal 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 internal margin in a white 
spot, which above and below is reddish brown. Fore wings a little paler beneath; the subapical
