DIPTEROUS PARASITES OF THE GIPSY MOTH {Porthetria dispar L.). 



The following are lists of the dipterous parasites reared and 

 recorded from Porthetria dispar L. and Euproctis chrysorrhma L. Each 

 list is supplemented by a list of recorded hosts for each species 

 enumerated. 



These lists have been compiled from various sources, the principal 

 being the "Katalog der Palaarktischen Dipteren/' Brauer & Bergen- 

 stamm's "Die Zweifliigler des Kaiserlichen Museums zu Wien/' Fer- 

 nald and Forbush's "The Gipsy Moth," and the senior author's "List 

 of parasites bred from imported material during the year 1907" 

 (3d annual report of the superintendent for suppressing the gipsy 

 and brown-tail moths). 



In the choice of names of the foreign tachinids the Katalog der 

 Palaarktischen Dipteren has been followed with the exception of a 

 few cases in which other names have been in use at the Gipsy Moth 

 Parasite Laboratory; in these few cases, to avoid confusion, no 

 change has been made.
