A. (A.) lacteicolor Viereck. 



This European species was originally introduced into the 

 state of Massachusetts on account of its effectiveness against the 

 brown-tail moth (Euproctis chrysorrhcea) . It attacks the small 

 caterpillars of both the brown-tail and the gipsy moth, and hiber- 

 nates with the former. In the spring the larva of the parasite 

 emerges and spins a white cocoon within the molting web. In ad- 

 dition to the insects above mentioned, it is on record as attacking 

 Datana and Hyphantria, making its usefulness all the more 

 assured. This species was planted at several points in Connecticut^ 

 in 1912 and 1913, to help control the brown-tail moth.
