190 THE CANADIAN ENTOMOLOGIST. 



such as nimbosa, atlantica, subjwicta, etc. In DiantJmcia, we have 

 D. bella, which represents the European D. Magnolii. America has the 

 usual preponderance of species, over seventy, while Europe has fifty- 

 eight of the two together. In my lists I have not separated the forms of 

 Dianthoecia, partly because the character was not easy to verify, or I had 

 only males, while the pupa, which presents some peculiarities as studied 

 in Europe, is quite unknown. PecuUar American Hadenoid genera, with 

 hairy eyes, seem to be Nephelodes, Admeiovis, Tricholita, Trichoclea, 

 Trichopolia and Eiipsephopcectes. 



I would here draw attention to the fact, that the generic characters in 

 the Noctuidce and the moths generally are of such a nature that a differ- 

 ence of opinion may legitimately arise. Undoubtedly, an ultimate and 

 better opinion may be obtained, but criticism is to be only indulged n^. 

 with that moderation which the nature of the subject demands. Far dif- 

 ferent is it with matters concerning positive or actual structure, where the 

 empiric has before him a certain specimen under the microscope. In 

 such cases, as with the genus Ceraihosia, where the describer erroneously 

 describes the neuration or other actual features, a positive error is com- 

 mitted and the author earns that measure of opprobrium which belongs 

 to defective work in Natural History. 



The European Hadenoid genera, with naked and lashed eyes, Episema. 

 Thecophora and Dichonia seem to be absent from our fauna. Folia, 

 which has the antennae tufted at base and usually pectinate or serrated in 

 the males, has eleven European species ; in the Bull. U. S. Geol. Surv, 

 VI., 266, I have given the list of ten American forms referred here, 

 whether they are all strictly correct, I am uncertain. The European 

 genera, with few species, Metopoceras, Cladocera^Heliophobiis, Ulochlcena, 

 Oxytrypia, are yet without described American species. Guenee's 

 Char.iptera festa seems to be the Cerma cora of Hiibner, and not to be 

 congeneric with the European viridana. Mr. Morrison's Va/eria Grotei 

 has a claw on the fore tibite ; consequently is not congeneric with the 

 European jaspidea, but seems to be allied to Dicopis. 



The genus Oncocnemis is a smooth, almost Agrotid form, considered 

 by Herrich-Schaeffer as allied to Heliothis with a claw on the front tibiae, 

 represented by two Russian species, of which confusa has a representa- 

 tive form in the Californian Behrensi. I have described the large number 

 of nineteen American species (three having yellow secondaries, Hayesi,
