156 THE CANADIAN ENTOMOLOGIST. 



representative, but I only know it from a description. The European 

 genus Trichosea (for ludifica = Diphthera^ incorrectly credited to 

 Ochsenheimer, see Check List, 1876, p. 36) seems allied to the forms I 

 have separated under Charadra, Walk. Raphia, Hubn, is represented 

 by our two species, f rater and abj'iipta — one with white, the other with 

 fuscous or gray secondaries. Instead of Panthea, we have the American 

 genus Platyceriira of Packard, which has strong resemblances to the 

 Dasychirince. In Arsilonche, we have either a representative or identical 

 species. So far as this tribe is concerned, the resemblance between the 

 fauna3 may be considered nearly as great as in the Thyatirince. 



Tribe Apatelini. 



It seems difficult to separate the following genera from the preceding 

 tribe. The labial palpi seem less dependent ; there is still a posterior 

 thoracic tuft, and the larvse are still hairy or peculiar ; some bore into wood 

 or pith to pupate ; a cocoon is generally made. But the form is smoother, 

 approaching the typical Noduitice. Diphthera Hiibn. f= J/i?;;/^; Auct, 

 not Hiibn.) has a representative species in our well-known D. fallax. 

 Apatela Hiibn, the typical genus, is resolvable into a number of groups, 

 based chiefly on the larval form. I do not think that Bijtler is warranted 

 in considering the species generically separable. He would refer the 

 moths on this account to actually different families. But the moths are 

 very similar in color and structure ; and I consider the larvae have under- 

 gone independent modification. The leading European groups are repre- 

 sented, and such species as the American A. occidentalism A. ftmeralis, 

 A. vulpina, described by myself, may be considered as a strictly " repre- 

 sentative " species. The character of the genus is changed, and its limits 

 perhaps reach with the Californian groups Merolonchc, and the Eastern 

 group Eulo?iche, not found in Europe. Our American forms outnumber 

 the European three to one, and this preponderance will be found in most of 

 the leading genera of the IVocttiidce, such as Apatela, Hadena, Mamestra, 

 Agrotis, Catocala. Whether we can separate the Bryophilini as a dis- 

 tinct tribe, is doubtful. The passage seems to be formed by the Ameri- 

 can genera Harrisimemna, Cerma, Polygrammate, Alicrocoelia. These 

 forms seem peculiar, as also the genus Chytonix, which follows Bryophila., 

 although, I am not certain of this. Guenee has apparently described the 

 type as a species oi Apamea, and thus related to Hadeiia. The thoracic 

 vestiture is, however, more like that oS. Bryophila, a lichen-feeding genus of
