LEPIDOPTERA HETEROCERA. 1187 



hind wings. Legs stout, pilose ; tarsi short, thick ; hind tibiae with 

 two very small apical spurs. Wings broad. Fore wings slightly 

 convex along the costa, falcate at the tips, oblique along the exte- 

 rior border; interior angle rounded; three inferior veins; second as 

 near to the third as to the first. Male. — Antennae very deeply pec- 

 tinated ; the branches on each side in pairs of equal length. Abdo- 

 men rather slender, extending to two-thirds of the breadth of the 

 hind wiugs. Fore wings much hooked at the tips, concave along 

 the exterior border. Hind wings shorter, broader, and more 

 rounded at the tips than those of the female. Female. — Antennae 

 minutely pectinated ; the branches on each side stout and single. 

 Abdomen extending to five-sixths of the breadth of the hind wings. 

 Fore wings very slightly falcate at the tips, nearly straight along 

 the exterior border. 



This genus unites the Drepanulidce and the Saturniidce, being 

 apparently as nearly allied to the latter as to the former.
