I have reared two parasites from this tinead. Centeterus 

 saturalis Ashm. and Bracon millitor Say. ; the latter may be 

 a secondary, but of this I am not certain. 



There are two leaf miners which attack the ground 

 cherry. Gelechia physaliclla and G. physalivorclla Q.\\d.m..; 

 while the one I have just described will make the third. 



I am deeply indebted to Prof. Iv. O. Howard for deter- 

 mination of parasites. To Dr. C. V. Rile}^ for indentification 

 of Gelechia nigrimaculclla and the use of his notes on the 

 same; and to Prof. F. M. Webster for notes and other favors. 



SOME INTERESTING INSECTS AT OBERLIN, O. 



BY LYNDS JONES. 



During the early summer months two Mole crickets 

 {Gryllotalpa) were taken at Oberlin. One adult, beneath the 

 electric light; the other, a young, beneath a board in the dry 

 portion of an ice pond. Both were in perfect condition. 



A small dragon-fly, which has been taken in large num- 

 bers in the grassy meadows, was referred to Prof. D. S. Kel- 

 licott. who has also found it in several localities. Prof. Kel- 

 licott considers it a new species. 



Two species of insects have been taken at Oberlin which 

 are new to the state. Aeschna clepsydra, on the ponds in 

 and about Oberlin ; Pezzotcttix hooseri, described by Blatchley 

 in the Canadian Entomologist for Feb. 1892. The latter was 

 abundant in a woods pond which had gone dry early in the 

 summer, and grown over with a dense vegetation. None 

 were found any where else in the region.
