Moth. — One S , three 9 . Antenna' of S more broadly pectinated than in S. niiiconvis. and less 

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

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

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

 wide, hollow triangle, the base of which 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 teguhe. 



Fore wings more produced toward the apex than in »S'. nnicornis and less acute than in 

 (S. ipomew: in the male, marked iiincli as in jV. iinivornis (the species connecting unicornis and 

 ijwmerc); ash gray, with no oli\e 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 subcostal venule, and one in 

 the submedian interspace. A basal curved, indistinct broken line (obsolete in 9 ) formed of longitu- 

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

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



' Dyar states (Trans. Amer. Ent. Soc, xxi. p. 204) that the larva described by French is not that of 5. leptinoides.
