Mr. Gerstencorn exhibited specimens of hybrid moths pro- 

 duced by mating a male Smerinthus ocellatus with a female 

 S..populi, both European species. The larvae of both forms 

 normally pass through four instars, but those of the hybrids 

 passed through only three. The adults parted from copula- 

 tion on May i4th and egg-laying began at once, the ova hatch- 

 ing on the 22d of the same month. The first moult was made 

 on May 27th, the second on June 2d, and the last on June 8th, 

 the larvae entering the ground to pupate on the i4th of that

 others came out shortly afterward ; the remaining pupae did 

 not disclose their imagines, and are passing the winter in good 

 condition.
