Moth . — $ and $ . Head more prominent than nsnal, on the vertex two tufts inclosing a 
triangular hollotv and xirojecting out between the antennie. Eyes naked. Antenme well 
pectinated on basal two-thirds, the outer third filiform (thicker and more ciliated in 8. apicalis 
than usual); in 9 simple. Palpi short, thick, blunt at the end, not extending beyond the front; 
second joint hairy beneath, the terminal scales reaching even with the tip of the third joint and 
meeting beneath; the third joint small, short. Maxilhe well developed (in 8, ^inicorniH)^ united, 
and as long avS the palpi. 
Thorax not regularly tufted, hut the ends of the tegnhe are slightly upturned and dark,* and 
on the underside below the head and in front of the legs is a large triangular tuft of long hairs, 
the ends of which are even with the front of the head. 
Fore wings a little less than one-half as broad as long, costa nearly straight, slightlj^ convex 
toward the apex, which is more pointed than usual; outer margin slightly angulated on the fifth 
subcostal venule, becoming more oblir|ue below. Venation: A short or long subrhoinboidal 
subcostal cell; costal region rather wide, the subcostal venules 1-4 not closely crowded; the 
third subcostal venule (ID) shorter than usual, otherwise the venation of both wings is much as 
in Heterocami)a. 
Hind wings somewhat produced or pointed at the apex, much more so than in Heterocampa; 
the costa nearly straight, slightly bent downward near the apex; outer edge long, the lower half 
disposed to be i)arallel with the costal edge of the primaries. 
Legs rather short; femora and tibim densely haiiy, the hind tibue are shorter than usual and 
with a broad tuft; the first p>air of tibial spurs small and slender, the outer one of the apical 
(discal) spurs twice the size of the inner one. Tarsi small. 
Abdomen much slendei’er than usual, with a distinct anal forked tuft, characteristic of the 
genus. 
Coloration: The species usually with dark ash-gray longitudinal slashes, costo-apical vdiite 
-and black spots, transvervse Avavy lines, and a curvilinear discal spot, except in 8. concinna., where 
the spot is a small black dot. The hind wings of the males are usually sordid white and those 
of the females dusky or mouse colored. 
The genus is recognized by the filifonn end of the male antenna* and the distinct male anal 
Muft; by the peculiar vestiture of the head; by the short, thick palpi, as Avell as the prominent 
head; characters in which it approaches Heterocampa, as well as the venation, though the hind 
wings are longer and more pointed than in Heterocampa.
