Notodonta stragula, Grote. 



Unnamed specimens of this species have been found by Mr. Walker 

 in the Brit. Mus. Coll. Specimens taken in Pennsylvania have since 

 been received by the Phil. Entomological Society ; it will probably oc- 

 cur throughout the Eastern and Middle States. 



Edapteryx bilineata. Packard MSS., (Plate 6, fig. 9. 9 .) 



This graceful North American Platypterid genus and species has 

 been communicated to me by Mr. A. S. Packai-d, Jr., its discoverer. 

 Subsequently the 9 specimen from which the accompanying figure was 

 made, was taken in Pennsylvania, and is now in the collection of the 

 Entomological Society. 



Heterocampa subalbicans, Grote. 



Mr. J. G. Bowles has sent me a 9 specimen of this species, taken 

 near Quebec, Canada.

I propose the present generic name instead of Lacinia^ which might 

 lead to some confusion, owing to its having been used in the Mollusca. 

 I have % specimens of both these species, quite distinct generically 

 from lliyatira as I have already shown, from Mr. Russell, of Quebec, 

 Canada. 



I find in C. B. M. the following expression of Mr. Walker's relating 

 to T. cijmatoplioroidcs: — "This species diff"ers much from the other 

 Thi/atirse, and will probably be separated from that genus."
