ICHNEUMON-FLIES, PART 2'. EPHIALTINAE 347 



that are separated by about 1.5 their diameter and some fine, weak, 

 oblique wrinkles; front tibia with a very strong median swelling; 

 epipleura of second, third, and fourth tergites, respectively about 

 2.3, 1.6, and 1.5 as long as wide. 



Black. Clypeus dark reddish brown ; palpi brown ; scape and fla- 

 gellum dark brown; tegula white; front leg fulvous, its coxa often 

 somewhat brownish ; middle leg fulvous, the apex of its femur faintty 

 infuscate, its tibia more or less infuscate basally, the fuscous fading 

 toward its apex, also with a subbasal paler band; hind coxa, trochan- 

 ters, and femur fulvous, the apical 0.17 ± of the femur infuscate; hind 

 tibia blackish, with a premedian white band that occupies about 0.25 

 its length; hind tarsus fuscous brown; wings subhyaline. 



The best diagnostic character for females is that the submedian 

 part of the face is more densely punctate than the metapleurum. In 

 species that might be confused with it the converse is true. Addi- 

 tional, confirmatory characters are the strong swelling at the middle 

 of the front tibia and the distinct infuscation at the base of the middle 

 tibia. 



Pimpla annulipes Brulle was described from "South America" but 

 for many years the Nearctic Coccygomimus aequalis and other Nearctic 

 species resembling aequalis were frequently determined as annulipes 

 Brulle. In 1918 Cushman (Proc. Ent. Soc. Washington, vol. 20, p. 9) 

 noted that the type locality was "South America" rather than North 

 America and a difference in color of the middle tibia between the origi- 

 nal description of annulipes and the Nearctic specimens. He proposed 

 that the Nearctic specimens formerly classified under annulipes be called 

 by the name aequalis. We studied Brulle's type in 1958 and found 

 that it is a large specimen (front wing 8 mm. long) of Coccygomimus 

 injlatus, which is known only from eastern North America. The type 

 of annulipes has no locality label, only a tag with the numbers "136" 

 and "38." Presumably the locality "South America," given by 

 Brulle, is an error and his type was actually from eastern North 

 America.
