Pimpla annulipes Say. 
This species, which is also an important and widespread parasite of 
lepidopterous larvee, and which is particularly noted as perhaps the most 
efficient enemy of the codling moth in certain parts of the United 
States, is also a parasite of the Orgyia, although a very insignificant 
one, at least during 1895-96, when compared with the species which we 
have just considered. It occurs in California, Texas, Missouri, Mich- 
igan, New York, Maryland, Illinois, and the District of Columbia, and 
probably has about the same distribution as Pimpla inquisitor. It is 
normally a somewhat larger species and is readily distinguished by 
the remarkably distinct and complete black bands on the tarsi and 
tibiw. It has previously been reared not only from the codling moth,

as above stated, but also from several Crambids, Tortricids, and Phy- 
citids, as well as from Papilio ajax and Datana ministra. In March, 
1890, it was bred from overwintering cocoons of Orgyia leucostigma 
received from M. H. Beckwith, Newark, Del., and in the course of the 
extensive rearing experiments of 1895 six specimens issued from 
cocoons of the tussock moth between September 16 and 25. Its life 
history is probably very similar to that of P. inquisitor. 
Pimpla conquisitor Say. 
This widespread and abundant Pimpla is one of the most important 
parasites of the cotton worm of the Southern States, Aletia argillacea. 
It is also parasitic upon the bagworm in New Jersey and the District 
of Columbia and is an important parasite of Phryganidea in California.
