6. Chytonix Sensilis. 



The species of this genus are allied to Bryophila^ 

 and have the vestiture of the thorax composed of 

 mixed, in part flattened scales. The dorsal line of 

 the body is tufted ; the form is more robust than 

 Bryophila ; in ornamentation there is a white spot 

 attached to the outer median line. M. Guenee 

 placed one species in Brijophila, one in Apamea. The 

 species are Jaspis and Balllatricula (perhaps not 

 distinct) and Sensilis. This latter has been col- 

 lected in Massachusetts by Mr. Thaxter. I have 

 not yet seen the male.

7. Agrotis Perattenta. 

 This species is found from Canada over the Eastern 

 and Middle States to the southward. It resembles 

 Agrotis Sigmoides in ornamentation, but it is a 

 smaller species, and wants the creamy shading over 

 the costa of primaries above from the base out- 

 wardly. I have collected it at Buffalo, N.Y., and in 

 the Katskills in June and July.

8. Agrotis Conchis. 



This fine species has been collected by Professor 

 Snow in Colorado. It is allied in ornamentation to
