Moth. — c5 and 9 . llead iiKjre i)romiiieiit than usual, on the vertex two talts iiiclosiiij;' a 

 triangular hollow and projecting- out between the anteunie. I'^ye.s naked. Auteunje well 

 l)ectiuated on basal two-thirds, the outer third liliforni (thicker and more ciliated in »S'. <(pic(ilin 

 than u.sual); in 2 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 develr)ped (in iS'. loiicontix), united, 

 and as long as the palpi. 



Thorax not regularly tufted, but the ends of the teguhe are slightly ui)turued 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, slightly convex 

 toward the apex, which is more jjointed than u.sual; outer margin slightly angulated on the liftli 

 subcostal venule, becoming more oblique below. Vciuvtion: A short or long subrhomboidal 

 subcostal cell; costal region rather wide, the subcostal venules 1— I not closely crowded; the 

 third subcostal venule (II3) shorter than usual, otherwise the venation of both wings is much as 

 in IIeterocami)a. 



Hind wings somewhat ])roduced or pointed at the apex, much more so than in lIeterocami)a; 

 the costa nearly straight, slightly bent downward near the apex; outer edge long, the lower half 

 disposed to be jtarallel with the costal edge of the ])rimaries. 



Legs rather short; femora ami tibia' densely hairy, the hind tibiie are shorter than usual and 

 Mith a broad tutt; the lirst pair 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 slenderer than usual, with a distinct anal f'ork<'il tuft, characteristic of the 

 genus. 



Coloration: The sixmucs usually with dark ash-gray longitudinal slashes, costo-apical white 

 and black spots, transverse wavy lines, and a ciuvilinear discal spot, excejit in S. conciinia, 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 filiform end of the nnile antenna' and the distinct male anal 

 tuft; by the peculiar vestiture of the head; by the short, thick palpi, as well as the prominent 

 head; characters in which it approaches Heterocampa, as well as the venation, though the hiud 

 wings are longer and more jxtiuted than in Heterocampa.
