Thi.s is as far as we are willing at the present time to as.sert positively. 

 It may be found that other changes will have to l)e made, as there un- 

 doubtedly will l)e through the whole family. There are nearly loo spe- 

 cies of Mr. Walker unitlentified, the types of which are in the British 

 Museum collection. 



There are also a considerable number of the species of Guenee and 

 l.ederer still undetermined. As almost all the material of these describ- 

 ers was from the East, their names will probably not much afiiect my o\\ n 

 species. 



A Hint to Rearers of Lepidoptera. 



Some time since my friend Mr. ."^eib of Newark, N. J., was so 

 fortunate as to obtain very many eggs o[ Sphmx lusa'tiosa, and a number 

 of larvai of Smerinthus Asiylus. Many went into the pupae state and were 

 in that condition kept in a cool cellar through the winter ; when there 

 was no longer danger of frosts the pupa; were placed in the open air. No 

 imagines emerged, however. Two years ago, I had the same experience 

 with Smermthus Astylus and Darapsa versicolor. I'he pupae being kept 

 m a cool cellar and removed when spring opened, to the open air. All 

 died and in the pupce e.xamined afterwards the imagines were found fully 

 developed and ready to emerge. It seems the simple change of condidon 

 was suflicient to destroy, though there was never enough of dryness tcj 

 work by itself any mischief Having since kept the same insects under 

 the same conditions but without change of atmosphere there has been al- 

 most no mortality among the pupx'. Mr. Hulst informs me that he has 

 had a pupa o{ Darapsa versicolor hatch out in June where the larvae had 

 escaped and pupated out of reach in die slide of folding doors, although 

 the room had been heated all winter with a hot air furnace. 



In all cases it seems the pupae do best when left undisturbed in their 

 cocoons and when not exposed to varying conditions of atmosphere.
