Moth. — One c$ . three 9 . Antennre of $ more broadly itectinated than in S. nniconii.s. and less 

 so than in »S'. ipomew. Head and thorax ash, with a delicate, pale, olive-green tint. Front of head 

 wliite, especially in i ; vertex olive-ash, with a blackish line on each side inside of the base of 

 the anteunje (not so distinct in 9 ). Thorax behind uniquely marked with a distinct, black, low, 

 wide, hollow triangle, the base of wiiicli extends straight across the thorax from one side to the 

 other, the two sides of the triangle being formed by the black edges of the teguhv. 



Fore wings more produced toward the apex than in <S'. unicornis and less acute than in 

 F\. ipomew; in the mah'. marked mucli as in S. unicornis (the species connecting unicornis and 

 ipomew); ash-gray, with no olive tint; the wings slashed with narrow linear black lines, of which 

 there are three on the base of the wing, one on the costa,oue on the subco.stal venule, and one in 

 the submedian interspace. A ba^al curved, indistinct broken line (ob.soletein 9 ) formed of longitu- 

 dinal black marks, and diffusely bordered externally with whitish gray. Beyond the cros.s line 

 the wing is whitish gray, becoming brownish on the inner edge of the wing. No distinct discal 



I Dyar st.-ites (Trans. Amer. Ent. Soc, xxi. p. 204 ) that the larva described by French is not that of .S. leplhwides.
