is smooth and the apices depressed in Eudryas. The clypeiis has a 

 wide and thin lengthily projected "plate," and the apices are 

 determinate in Copidryas. The clvpens has a circular rough projec- 

 tion and the male wings are almost denuded, the apices roundedly 

 produced, the neuration aberrant in the Cuban Eiiscirrhopterus. 

 Ciris is distinguished by the pectinate antennae and shape of wings ; 

 it is the lowest of the genera. The group is not Noctuidous, as 

 some Continental authors seem to believe, but related to Alypia 

 and Castnia^ as sufficiently explained by Dr. Packard. I have 

 referred the African genus Ovios here, in a former paper, and in 

 my " Catalogue," I call the group Eiidriini. The list there given 

 is defective and should be amended as foUows:

The specimen is paler than our Eastern examples, but seems 

 to belong to the same species. One specimen. New Mexico. 

 Emplocia Cephisaria. n. s. 



? . Aspect of Melanchroia CepJiise. Blue black above, im- 

 maculate ; the short fringes are white. Beneath black, with the 

 base of both wings on costal region shaded' with pale lake red. 

 The collar and fore legs on the inside touched same color. Body- 

 black, as are the antennae and legs. Expanse 30 mil. 



In this species the primaries above at base show an extremely 

 faint sub-costal shade of lake red. One specimen (868).
