Genus 6. ODONESTIS. 



Large insects. Antennas in the male very strongly 

 pectinated, palpi in both sexes long and porrected ; thorax 

 and abdomen very stout, the latter tufted in the male ; wings 

 broad, the fore wings angulated at the tip. 



We have only one species. 



1. O. potatoria, L. — Expanse of the male, 2 to 2^ 

 inches, of the female 2^ to 2|. Male dull red, clouded with 

 yellowish; female yellowish buff; both with beak-like palpi,

 which have two small central white spots.

 area ; first line slender, nearly perpendicular but slightly bent 

 in the middle, red-brown, not conspicuous ; second line 

 sharply marked and distinct, arising on the dorsal margin 

 before the middle, and proceeding with a smooth curve to the 

 apex, dark chocolate edged outwardly with purplish ; outside 

 this, from the dorsal margin to near the apex, is a curved
