Parasetigena segregata Rond., one of the Eurovean tachinid parasites of 
the gipsy moth, which was obtained from several parts of Europe last summer, 
hiberna ted successfully in the hibernating eages in the laboratory yard at - 
Melrose Highlands. Seven strong colonies of adults, each containing over . 
1,000 fertilized females, have been liberated in the moth-infested area of 
New England this spring. One small colony of mated adults of Sturmia gilva 
Hartig, also a gipsy moth larval parasite, has becn liberated this spring, 
These flies were obtained by collecting the cocoons of one of its hibernating 
hosts, Lophyrus pini L., in southern Poland early this spring. These cocoons 
were taken from Bremen, Germany, where the warasites were reared, and shipped 
tq the welrose laboratory as puparia, The spring colonization of Anastatus 
pitas Cciatus Fonsc, is practicelly completed, nearly 2,500,000 parasites haying: 
been colonized.
