127. APANTELES MELANOSCELUS (Ratzeburg). 



Mici'ogaster nielanoscclus Ratzeburg, Ichn. d. Forstins., vol. 1, 1844, p. 74. 

 {Microgaster inelanoscelus Hatzehurg) = Apanteles difficiUs 'Nees, Marshall, 

 Trans. Ent.. See. London, 1885, p. 187. 



Habitat. — Europe ; and New England, over the gipsy-moth area. 



Host. — Porthetrla dispar Linnaeus. 



Cocoons. — Yellowish-green ; solitary. 



This species, introduced from Europe as an enemy of the gipsy 

 moth, and successfully established in the gipsy-moth area in New 

 England, is verj'' close to solitarius, which it resembles biologically as 

 well as structurally; possibly it is not more than a variety of that 

 species, differing only in the blackish posterior femora, and in the 

 third abdominal tergite being somewhat less roughened. There can 

 be no question that Marshall erred in placing melanoscelus in the 

 synonymy of difficilis. 



Represented in the United States National Museum by several 

 specimens bred from the gypsy moth in Europe, and by several others
