Moth . — Front of the bead rather narroiv, densely pilose between the antennte, the scales being 
long. Anteniue almost plnmose in S , being pectinated to the tips, with nuusually long branches; 
in 9 subsimple. Palpi very slender, porrect; second joint a little jiilose beneath; third joint 
slender, acute. Eyes naked. Thorax with a slight low tuft. 
Fore wings two-thirds as broad as long, broad snbtriangular; costa a little full at base, beyond 
straight; apex rectangular, not falcate; outer edge equal in length to the internal, not scalloped, 
convex. Yeuation: The costal region is quite broad, and the first to the fourth subcostal venules 
arise very 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; fifth 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 oblique; the origin of the first cubital venule 
(III3) is unusually remote from that of the second. 
Hind wings short and broad, much rounded at the apex. Yeuation: The subcostal vein 
divides farther out from the discal vein than iu Xylinodes and much farther out than in Schiznra, 
and the common origin of the hinder discal and first cubital venule (III3) is remote from that of 
the second cubital venule (lYi), The internal vein (YII) is very short. The legs are very long 
and slender, hinder pair of tibhe 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 : Ocheroiis or pinkish ocherous, with pink lines and scales; a long discal line. 
This genus is characterized by the broadly pectinated or plumose autenuic, the branches 
extending nearly to the tip; by the long slender palpi and legs, with the two pairs of long tibial 
spurs; by the plain nuscalloped fore wings, the plain, not tufted, thorax, and the peculiar style of 
coloration. Bj^its venation and larval characters it stands near Xylinodes and Schizura, although 
the general ai^pearance of the moth would not perhajis lead to this view. 
Larva , — 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; the dorsal region 
between these two segments green. 
Freshhj hatched larva , — Much like the young of Schizura in shape and in the position and 
shape 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. 
Fu;pa, — Subterranean, the larva spinning no .cocoon.
