338 U. 8. NATIONAL MUSEUM BULLETIN 216 



carinae of propodeum usually distinct on its basal 0.3 ±, subparallel; 

 abdomen rather closely punctate; first tergite short and wide ; epipleura 

 wide throughout, except in males of stricklandi and hesperus; upper 

 valve of ovipositor not depressed apically and without transverse 

 ridges. The epipleura of the second, third, and fourth tergites are 

 respectively somewhere near 2.8, 2.0, and 1.7 as long as wide in males 

 and somewhere near 2.0, 1.7, and 1.5 as long as wide in females 

 (fig. 329,1). 



This group is mostly Holarctic and Neotropic. Besides the seven 

 species treated below as Nearctic, it includes the European Ichneumon 

 contemplator Miiller 1776, Pimpla melanacrias Perkins 1941, and 

 Pimpla spuria Gravenhorst 1829; the Japanese Pimpla nipponica 

 Uchida 1928 (described as a variety of P. spuria) ; the South American 

 Pimpla rujipes Brulle 1846; the Chilean Pimpla fuscipes Brulle" 1846, 

 (=P. fuscipennis Spinola, 1851, new synonymy); an undescribed 

 species from Chile; and Pimpla sordidella Holmgren 1868, from Tahiti. 

 These species are new combinations in the genus Coccygomimus. 



11. Coccygomimus hesperus, new species 



Male: Front wing 3.7 to 4.7 mm. long; epipleura of second, third, 

 and fourth tergites respectively about 4.5, 3.1, and 1.85 as long as 

 wide. 



Colored like the male of C. stricklandi except that the maxillary 

 palpus and sometimes the labial palpus is mostly white, the tegula is 

 basally white to entirely white, and that the pale band on middle 

 tibia is a little more distinct; wings subhyaline. 



Female: Front wing 3.5 to 6.0 mm. long; face with moderately 

 sparse punctures, the punctures separated by about 1.4 their diameter; 

 mesoscutum with dense hairs anteriorly, the rest of its surface with 

 the hairs moderately sparse, their sockets separated by about 0.7 

 their length; epipleura of second, third, and fourth tergites respec- 

 tively about 2.5, 1.5, and 1.4 as long as wide. Otherwise structurally 

 similar to the female of C. stricklandi. 



Coloration as in the female of C. stricklandi except that the hind 

 tibia and tarsus vary from blackish with a poorly defined submedian 

 pale band on the tibia (as in C. stricklandi) to entirely fulvous. 



There is a distinguishable race in southern Arizona and New Mexico 

 which has the tegula of the female fulvous or light brown (rather than 

 brown or black) and the metapleurum usually with a moderately large 

 ferruginous mark next to the hind coxa . 



This species is compared with C. stricklandi because it is in the 

 same species group, but it is also very similar to C. varians. Males 

 are hardly distinguishable from those of varians. Females differ from 

 those of varians in having the epipleura of the second tergite wider,
