14 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 120 
Hampson described the color of the pale areas of the wings as 
“orange-yellow.”” The female specimen in the U.S. National Museum 
is deep yellow with a slight orange tinge. It is not nearly as orange 
as indicated by the figure provided by Draudt (1919). The males 
(fig. 12) resemble the female, except the pale markings of the wings 
are slightly smaller, pale yellow, nearly white in color, and the ventral 
surface of the body is nearly uniformly dark brown or black. There 
is a lateral line of yellow on abdominal segments 4-7. One male 
has a few yellow scales on abdominal sternite 3 and some of the males 
have some yellow scales and hair between the bases of the forelegs. 
Hampson stated that the type has a broad ventral yellow stripe in 
addition to the lateral abdominal stripes. In the female in the U.S. 
National Museum the abdomen has been removed and the genitalia 
have been prepared on a slide; thus, the coloration of the abdomen 
is not determinable. The orange-yellow, lateral spots of the patagia 
of the male are like those of the female. 
Cisaucula, new genus 
Type-species: Copidryas peruviana Druce, 1910=Cisaucula peru- 
viana (Druce). 
The species on which this genus is based is not congeneric with 
the species of Copidryas Grote. The modification of the aedeagus 
(apical half greatly reduced in diameter and very strongly sclero- 
tized) indicates it belongs with the complex of genera including 
Rhosus Walker, Erocha Walker, and Aucula Walker. This complex 
contains remarkably similar groups that are badly mixed and that 
differ mainly in general pattern of maculation and in characters of 
the male genitalia. Copidryas peruviana Druce differs from all of 
the species assigned to the three previously mentioned genera in the 
pattern of maculation of the wings (figs. 11, 21) and in having simple 
antennae in the male (bipectinate in the other genera). The male 
genitalia are also distinct although some characters do agree with 
one or another of the other genera. 
Description: Eyes large, hemispherical, naked; ocelli small, adnate 
to upper margin of eye immediately caudad of base of antenna; 
antenna simple, pubescent ventrally; frons produced into a blunt, 
rounded prominence with slightly raised rim, the latter rounded 
ventrally and convergent dorsally, prominence exceeding anterior 
margin of eye by half length of eye; labial palpus small, slightly ex- 
ceeding frons, slightly oblique, third segment slightly decumbent, 
clothed with appressed scales, slightly shorter than second segment, 
second and third segments fringed ventrally with long, loose, hairlike 
scales. Vestiture of head and thorax of hair or hairlike scales, without 
crests. Abdomen with a prominent dorsal tuft of hairs on first seg-
