 Greatly enlarged. (Bull 91, U.S. Bur. of Knt.) 



Calosoma sycophanta, a valuable predaceous enemy of the Gipsy and Browiilail Caterpillars. 



That this and other not mentioned parasites are making their pre- 

 sence felt may be realized when it is stated that fully 50 per cent of the 

 ^g'^s, caterpillars or pupae of the ^psy moth were destroyed by import- 

 ed parasites in 1912, in the central region infected.
