14 CUCKOOS AND SHRIKES IN RELATION TO AGRICULTURE. 



americana) were found in several stomachs. Ants, too, are frequently 

 eaten; probably captured when crawling over leaves or branches — 

 possibly when tending their dairies of plant lice. One stomach from 

 western Pennsylvania, taken on June 2, contained, among other insects, 

 2 cnrious heads of ants, which were identified by Mr. Pergande, of the 

 Division of Entomology, as belonging to the genus Cryptocarus. This 

 genus is not known from the United States, but is abundant in Mexico 

 and the West Indies, The bird was probably a late migrant. A few 

 other Hymenoptera were found, among them a specimen of that curious 

 long-bodied creature, Pelecinus polyturator. In the stomachs examined 

 a few dragon flies were detected, but not enough to constitute a per- 

 ceptible percentage. There were also some spiders, mainly Phalam/idw. 

 As a matter of interest to the entomologist, as well as the orni- 

 tliologist, a list of insects identified in the cuckoos' stomachs is
