AMERICAN LEPIDOPTERA. 263 



workers on our Noctuids were to some extent avoided and rectified. My 

 Hadenas have naked eyes, my Mamestras hairy ones, my Agrotids spin- 

 ose tibiae. I have recognized the presence of important genera such as 

 Oncornemis in our fauna, without the European species at hand which 

 Mr. Smith now has in such profusion. Undoubtedly the work is now 

 easier with all the determinations made. My school friends Mr. Graef 

 and Mr. Tepper have gradually acquired most all the European species, 

 and such a person as Mr. Smith can easily arise and go through the labor 

 of examining their rich collections and getting our fauna in details into 

 correspondence with the European. But with only a book before me 

 and a specimen of the first North American Oncocnemis, it was not so 

 easy to write with a feeling of certainty. To return to this genus, as it 

 cannot be called Anthoecia (which is a different genus), it ought in jus- 

 tice to be called by the name I retained for the larger number of its 

 species and which, moreover, is better sounding. I shall continue, there- 

 fore, to use the term Lygr anthoecia, and simply refer the species of 

 Schinia. as congeneric with L. marginata. The use of Thalpochanes 

 rests on similar grounds. 



DISOCNEMIS, Gr. 



In my notes on Mr. Neumogen's collection I made Mr. Henry Ed- 

 wards' species Belladonna, the handsomest of the group, the type of 

 this new genus, leaving Oregona, unrecognized by me as the same as 

 the European Ononis, in Melicleptria. In describing Melaporphyria I 

 noted the narrowed eyes, shared by this genus, but the present differs 

 by the tibiae having two instead of three claws as stated by Mr. Smith. 

 The two species are also alike in form of wing and aberrant from lm- 

 mortua in this respect. The naked eyes are narrowed or ovate. The 

 infra-clypeal plate is more marked in both species than in Melaporphyria. 

 The head is less prominent. Palpi heavily fringed, rather short, and the 

 vestiture is longer and more hairy than in my genus Melaporphria, with 

 which the present generally agrees, as shown by Mr. Smith. The type 

 is Melicleptria Belladonna , Hy. Edw. 



TRICOPIS, Gr. 



Mr. Smith uses characters given in my table in the Bull. Buf. Soc. 

 as sectional. The produced infra-clypeal (as this term is used by 

 me) plate and the peculiarity of tibial armature are held by me to be 

 of generic importance. Aleucis, of Harvey, is said not to have the 

 plate prominent and is, perhaps, a Lygranthoecia. When we have two 

 characters in combination it is enough to give sanction to the genus which
