ICHNEUMON-FLIES, PART 2 1 EPHIALTINAE 345 



N. Y., E. F. Taschenberg. 9, from Tolype velleda, Long Island, 

 N. Y., June 23, 1905, G. P. Engelhardt. 



This is an exceptionally common species, occurring in the Al- 

 leghanian, Carolinian, and Austroriparian faunas. Its habitat is 

 deciduous woods with ground cover. Adults occur throughout the 

 growing season. 



14. Coccygomimus nudus (Townes) 



Pimpla nuda Townes, 1940, Ann. Ent. Soc. America, vol. 33, p. 306; 9. Type: 

 9, Bear Mt. State Park, N. Y. (Townes). 



Male (not known with certainty but several males probably of this 

 species are as follows): Front wing about 6.5 mm. long; similar to 

 the male of C. aequalis except that the epipleura of the second tergite 

 seem to be slightly wider and the hind femur has the apical 0.18± 

 fuscous, which is a little more fuscous than usually found in C. 

 aequalis. These differences are not great or certain enough to permit 

 a definite separation between males of the two species. Unlike the 

 female, these supposed males of C. nudus have the tegula white and 

 lack the bald area along the upper edge of the hind tibia. 



Female: Front wing 4.5 to 8.0 mm. long; face sparsely punctuate, 

 the punctures on the submedian part of face separated by about 2.5 

 their diameter; temple in profile about 0.46 as long as eye; mesoscutum 

 with moderately dense hairs anteriorly, the rest with sparse, scattered 

 hairs; lower part of mesopleurum with fine sparse punctures that are 

 separated by about 3.0 their diameter, without wrinkling; meta- 

 pleurum with fine punctures that are separated by about 2.0 their 

 diameter, and with some oblique wrinkling in its lower hind part; 

 front tibia with a moderately strong median swelling; upper edge of 

 hind tibia with hairs much sparser than elsewhere on the tibia, in 

 some places on the upper edge the hair sockets separated by more than 

 the length of the hairs (all other Nearctic species of Coccygomimus 

 lack this character); epipleura of second, third, and fourth tergites 

 respectively about 1.55, 1.3, and 1.2 as long as wide. 



Black. Palpi fuscous; flagellum dark brown; tegula dark brown 

 to black; front and middle legs fulvous, the front coxa more or less 

 infuscate and middle tibia faintly infuscate at the base; hind coxa, 

 trochanters, and femur fuscous, the femur with its apical 0.15± 

 infuscate; hind tibia blackish, with a white submedian band occupying 

 about 0.24 its length; hind tarsus fuscous or brown; wings subhyaline 

 or rather weakly infuscate.
