The slides of genitalia made during the progress of my studies on 

 this group are all in the IT. S. National Museum, as are also the types 

 of most of my species, together with good series of most of the speci- 

 mens. The material iu this collection has served as the base upon 

 which this work has been built. 



The species not noticed herein any way do not belong to the genera 

 to which they are referred in the lists. Mr. Morrison's species Tocnio- 

 campa vegeta and T. carina are samples of such 



I believe that I know all the species save orobia Harvey and a<jrotifor- 

 mis Grt., which I have never identified in collections. 



BARATHRA IIbn. 

 Verzeicbniss, 218. 

 Coirimamestra Gut., Ann. and Mag. N. II. [London], 1833, 54. Tr. Kans. Ac. VIII, 55. 

 Eyes hairy, tibia 1 - not spinose, anterior with a single long curved 

 claw at tip. The front is smooth, the vestiture rather coarse, scaly ; 

 head somewhat retracted, palpi not attaining the vertex. Thoracic 

 vestiture dense, scaly, giving the thorax a square outline; a divided 

 anterior, and somewhat truncate posterior tuft. Dorsum of the abdo- 

 men tufted, and in the male there are small lateral tufts. Antenna} of 

 male simple, or slightly ciliate. Primaries elongate, widening out- 

 wardly; apices distinct; outer margin oblique. The genitalia of the 

 male are peculiar. The harpes are suddenly constricted toward tip, and 

 then modified into a deeply excavated shell with irregular outlines. 

 Toward the outer margin this shell is densely clothed with spinnles. 

 The clasper is a very short beak like projection at the point of constric- 

 tion of the harpes. 



This genus is very like Mamestra; so like, indeed, that the European 

 entomologists do not recognize in their species brassicae, a distinct 

 generic type. The character — armed tibia, combined with hairy eyes, 

 is, however, so unusual, that it obtains considerable value and, addeil 

 to the very peculiar genitalia of the male, seems to authorize the genus. 



Fliibner first proposed the generic term Baratkra in the verzeicbniss, 

 and Mr. Grote afterward described the genus Copimamcxtni with the 

 same type. 



There are two species thus far discovered, which may ultimately
