﻿2 BTJLUBTIN 1363, U. S. DEPABTMENT OP AGRICULTUEE 



of 1915, arrangements were made by A. F. Burgess, in charge of 

 the gipsy-moth investigations at Melrose Highlands, Mass., for the 

 collection of larvaB and the study of their parasites. 



SOURCES OF COLLECTIONS AND DATA 



The laboratory is so situated that the opportunities for obtaining 

 large collections of insect material are numerous. In addition to 

 the laboratory force, quarantine inspectors in infested areas, scouts, 

 local moth superintendents in Massachusetts, and people interested 

 in the moth work in all of the New England States gather material 

 and send it to the laboratory for study. The larval collections re- 

 ceived from 1915 to 1922 include the following : For 1915, 68 species, 

 18,457 larvee; 1916, 151 species, 20,712 larvae; 1917, 140 species, 23,086 

 larvae; 1918, 117 species, 20,427 larvae; 1919, 141 species, 54,628 larvae; 

 1920, 144 species, 58,313 larvae; 1921, 136 species, 57,512 larvae; 1922, 

 138 species, 49,421 larvae. 



During the eight years in which larvae have been collected there 

 have been received at the laboratory about 300 identified species, to- 

 gether with many specimens which failed to produce adults and 

 the identity of which can never be established. A list of the host 

 insects of Compsilura received during this period is given in Table 1.
