amerieana) 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, 
li curious heads of ants, which were identified by Mr. Pergande, of the 
Division of Entomology, as belonging to the genus (Jryptocaru.s. 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 (lies were detected, but not enough to constitute a per- 
ceptible percentage. There were also some spiders, mainly Phahtn<ji<l<v. 
As a matter of interest to the entomologist, as well as the orni- 
thologist, a list of insects identified in the cuckoos' stomachs is
