Imago. — c? . Front of the head a little broader than in Ormiscodes. Antennae shorter 

 and wider than in that genus; as usual pectinated to the tip, the extremity of which is subfili- 

 form; antennae joints shorter than in Ormiscodes. Two pairs of pectinations, the distal pair 

 larger than in Ormiscodes, those on the inner side only slightly shorter than those on the outer 

 side. Palpi ascending and projecting beyond the front, much larger, longer and wider, with 

 shorter, closer squamation than in Ormiscodes; third joint distinct, about one-half as long as 

 second joint is wide, while in Ormiscodes they are depressed, small, short, and indistinct and 

 with irregular scales. 



Thorax with scattered, long, flattened hairs, as in Ormiscodes. Fore wings more falcate 

 than in Ormiscodes, costa fuller, more convex toward apex ; outer edge short ; wings subf alcate, 

 but not excavated behind the apex. Hind wings regularly rounded on the apex and inner 

 angle, much more so than in Ormiscodes, and of quite different shape from that genus. 



Venation: Vein II t [IIIj of revised nomenclature] arises near the outer end of the discal 

 cell, i. e., much nearer the origin of the anterior discal vein, and the two discal veins make a 

 straight line, not an oblique one as in Ormiscodes cinnamomea, and they are situated inside of 

 the middle of the wing. On the hind wing veins II 1; II 2 , II 3 , arise farther apart than in 

 0. cinnamomea. 



Markings: No white discal spot, but an irregular dark one. Purple tints with purple- 

 brown markings, and roseate hind wings. The abdomen is banded with yellow and black. 



This genus is based on Ormiscodes rosea Druce. 



Geographical distribution. — Vera Cruz, Mexico. 



This genus differs from Ormiscodes not only in the venation, but in the larger palpi, the 

 shorter, broader antennas, subfalcate fore wings and more rounded hind wings. The thorax 

 is equally shaggy and wooly and the legs thick and hairy. In the shape of the fore wings and 

 absence of a discal spot it somewhat approaches Ilylesia.

Imago. — One c? . Front of head rather wide. Palpi unusually large, broad and stout, 

 with short hairs, extending well beyond the front; third joint not so long as the second is wide. 

 Antennae pale, not so long as in 0. cinnamomea, but of the same hue. Thorax dark brown, 

 with longer irregular dark hairs. 



Fore wings short, moderately broad, costa well curved on the outer third; apex much 

 more rounded than in 0. cinnamomea. Both pairs of wings purplish brown; no definite basal 

 line, but the middle of the wing is occupied by a V-shaped rose-lilac area, the apex of the V 

 resting on the inner edge just beyond the middle of the wing, and the two arms ending, the inner 

 on the inner fourth and the outer on the outer fourth of the costal edge, and inclosing the 

 large brown narrow irregularly triangular discal spot. The outer arm of the lilac V is bent 

 inward on the costa, and beyond this bend is a large dark costal brown spot extending to the 

 apex. No definite line beyond the extradiscal. Fringe on both wings brown, white at the ends 

 of the veins. 



Hind wings deep roseate on the basal hah. An oblique obscure dark diffuse discal dis- 

 coloration extending to the extradiscal line; a broad heavy diffuse dark brown line, curved 

 opposite the discal spot. Between this and the edge of the wing is a broad obscure dark band. 

 Margin of wing; clear roseate brown.
