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 chrysorrh@a 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 Paliarktischen 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.
