which we have one Eastern species, the Bryophila lepidula Gr. On the 

 whole, the resemblance of the two faunas is here, again, quite close. 

 Genera with single species, peculiar to each fauna, occur, but the parent- 

 age is obvious, and but small modifications seem to be offered. These first 

 tribes of the Noduiiice. seem to belong to the circumpolar element in our 

 moth fauna, with the Thyatirince. The position formerly given by me to 

 the American Dicopini seems susceptible of a change. If we place the 

 Agrotini where Lederer puts them, these Dicopid genera, with a claw on 

 the front tibiae, seem to fall in better between the Agrotini with spinose, 

 and the Hadeiiini with unarmed tibia\ They have, especially Dicopis, a 

 decided resemblance to the Hadenini ; but the larvse are apparently un- 

 known, and may assist our classification by offering determinative char- 

 acters. 



The following table will assist in giving an approximate idea of the 

 correspondence between the two faunae. Allowance must be made that 

 the North American fauna is less exhaustively known : —
