moderately elongate, with large, dense, strong pecten. Labial 

 palpi very short, filiform, drooping. Maxillary palpi obsolete. 

 Posterior tibiae densely clothed with very long hairs above 

 and beneath. Forewings with vein 1 simple, 2, 3, and 4 

 almost from a point, 5 and 6 absent, cell open between 4 and 

 7, 7 and 8 stalked, 7 to hindmargin, 10 absent, 11 from middle. 

 Hindwings f, lanceolate, cilia 3 ; veins 3, 4, 5 absent, cell 

 open between 2 and 6, 6 and 7 stalked, 6 to hindmargin. 



The natural group to which this and the following genus 

 belong I formerly regarded as a distinct family {Bcdclliada), 

 separable from the Argyrcsthiada proper by the hairy pos- 

 terior tibiae and degraded neuration of hindwings ; but from a 

 study of more extensive material I think it better to unite 

 them. The structure of the head is characteristic and iden- 

 tical, and the change of neuration is gradual.
