2Loth. — Fiont of the bciul rather narrow, densely pilose between the antenna', the .scak's being 

 long. Antennse almost plumose in S , being pectinated to the tips, with unusually long branches; 

 ill 9 snbsiiiiple. Paljii very slender, porrect; second .joint a little pilose beneath; third joint 

 slei der, acute. Eyes naked. Thorax with a slight low tuft. 



Fore wings two-thirds as broad as long, broad subtriangular ; costa a little full at base, beyond 

 straight; apex rectangular, not falcate; outer edge equal in length to the internal, not scalloped, 

 convex. Venation: The costal region is quite broad, and the lirst to the fourth subcostal venules 

 arise vei'y near to each other and end at the costal edge very near together; there is a long narrow 

 subcostal cell, and the second subcostal venule arises a little beyond the middle of it, while in 

 Xylinodes it arises near the distal end; lifth subcostal venule shorter than usual; the discal veins 

 are situated beyond the middle of the wing, and the course of the two is unusually oblique, the 

 hinder one not being curved as it is in Xylinodes, but obli(iue; the origin of the first cubital venule 

 (III;!) is unusually remote from that of the second. 



Hind wings short and broad, much rounded at the apex. \'enation: The subcostal vein 

 divides farther out from the discal vein than in Xylinodes and much farther out than in Schizura, 

 and the common origin of the hinder discal and first cubital venule (IIIj) is remote from that of 

 the second cubital venule (IV,). The internal vein (VII) is very short. The legs are very long 

 and slender, hinder pair of tibia; with two pairs of very long spines. The tip of the abdomen 

 is in the male pointed and slightly tufted when the claspers are outspread. 



Coloration: Ocherous or pinkish ocherous, with pink lines and scales; a long discal line. 



This genus is characterized by the broadly iiectiiiated or plumose antenna-, the branches 

 extending nearly to the tip; by the long slender palpi and legs, with the two pairs of lon.g tibial 

 spurs; by the plain unsealloped fore wings, the plain, not tufted, thorax, and the peculiar style ot 

 coloration. By its venation and larval characters it stands near Xylinodes and Schizura, although 

 the general appearance of the moth would not perhaps lead to this view. 



Lnrra. — Closely allied in its general shape and style of coloration to Xylinodes and Schizura. 

 A double red hump on the first and a tubercle on the eighth abdominal segment; tiie dorsal region 

 between these two segments green. 



FrKshhj hatched larva. — Much like the young of Schizura in shape and in the position and 

 sha])e of the conical tubercles. Body thrice ringed with red, the dorsal tubercles of first and 

 eighth abdominal segments scarcely larger than those on the othei segments. 



Pupa. — Subterranean, the larva spinning no cocoon.
