LEPIDOPTERA HETEROCERA. 1227 



Body stout. Antennae as long as the thorax. Thorax with a 

 lappet on each side. Abdomen not extending so far as the hind 

 wings. Wings rather long, moderately broad. Fore wings slightly 

 convex on the apical part of the costa, more or less acutely angular 

 at the tips, oblique and almost straight or hardly concave along the 

 exterior border. Hind wings rather broader than the fore wings. 

 Male. — Antennae very deeply pectinated, except near the tips, where 

 they are serrated with alternate short and very short teeth ; branches 

 of equal length, slender, ciliated, in pairs. Female. — Antennae very 

 slightly pectinated, with alternate very short and rudimentary 

 branches. 



This genus differs from Anther •cea in its more elongated fore 

 wings, and more especially in the vitreous spot of the latter. These 

 have no trace of the ocellus which, like that on the hind wings, 

 appears on the fore wings of all the Anthercece, though in several 

 species of the latter genus it is much smaller than the hind wing- 

 ocellus. It seems to connect the Drepanulidce with the Satur- 

 niidcB by means of the genus Cricula.
