298 BOARD OF AGRICULTURE. [P.D.No.4. 



Sarcophaga, two species, determined by Dr. S. W. Williston. 



Schiner expresses very grave doubts whether the species of Sarco- 

 phaga ever feed on anything but dead animal matter, while Brauer 

 states that their larvae are sometimes parasitic. 



Cyrtoneura stabulans, Fall., determined by Dr. S. W. Williston. 



According to Hartig and Bremi, the larva of this species is sometimes 

 foimd in the larvae of certain Bombycid moths. 



One of the true bugs, Podisus spi7iosus, Dall., was often found destroy- 

 ing the caterpillars of the gypsy moth, and predaceous beetles, ants, 

 spiders, toads and poultry were also found at the same work, while no 

 less than twenty species of birds were observed feeding on the cater- 

 pillars. 



After consulting with Drs. Farlow and Thaxter on the subject, it was 

 deemed impracticable to attempt the use of vegetable parasites in 

 destroying the gypsy moth. 



Respectfully submitted, 



C. H. FERNALD.
