THE GYPSY MOTH. 



Many of the names are taken from a list furnished me by 

 Dr. S. W. AVilliston : 



Eiorista Incornm Meig. 



Exorista (Myxexorista) libatrix 



Pan 7.. 



Exorista erythrostoma Hrtg. 

 Parexorista sussorans Kond. 

 Meigenia bisignata Schin. 

 Tachina beUa Meig. 

 Tachina pinivora Ratz. 

 Tachina larrincola Ratz. 

 Tachina monacha Eatz. 

 Tachina noctuarum R. D. 

 Tachina quinqnevitala Hrtg. 

 Tachina rustica Fall. 

 Tachina larvicola Hrtg. (?) 



Tachina moreti R, D. 



Tachina (Echinomyia) conjugate 



Rond. 



Tachina (Echinomyia) fera L. 

 Tachina bimaculata Hrtg. 

 Eutachina larvarum L. 

 Phorocera concinnata Meig. = M. 



serrieventris Rond. (?) 

 Sarcophaga affinis FalL 

 Thelymorpha vertiginosa FaU. 

 Argyroph} T lax gilra Hrtg. 

 Parasitigena segregata Rond. 

 Macharsea serriventris Rond. 

 Chsetomyia crassiseta Rond, 



It will he observed that the single species of Tachinidae 

 thus far known to infest Porihetria di&par, in North 

 America, belongs to a different genus, or sub-genus, from 

 any in the above list, all of which are Tachinids except one. 

 It will be of interest to determine the earlier or normal host 

 of Ach aetoneu ra fernaldi. 



Predaceous Diptera. 



Of the predaceous Diptera the following species have 

 been taken feeding upon the imagoes of the gypsy moth : 

 DaJsyTlis sacrator Walk., attacking the females while laying ; 

 Atilus tsericeus Say, capturing the male imagoes on the 

 wing. 



Predaceov* Hemiptera Heteroptera. 



The following account of the predaceous Hemiptera Heter- 

 optera, known to feed on the gypsy moth, has been prepared 

 for this report by A. H. Kirkland, B.Sc., assistant entomol- 

 ogist. 



An important factor in the destruction of the gypsy moth 

 caterpillars is the aid rendered by several species of pre- 

 daceous bugs, which, in badly infested localities, attack the 

 caterpillars in considerable numbers, and in some places 

 apparently feed upon them in preference to any other kinds 

 of Lepidopterous larvae. The predaceous bugs thus far found 

 feeding upon the gyp*y moth are Podisus cynicu* (Say;,
