Figure 64. — Localities for 

 Dolichomitvs pterelas. 



tudinal carinae of propodeum divergent, obsolescent, distinct only 

 on basal 0.15 to 0.4 of the propodeum; abdomen narrow at base, the 

 rest much broader; first tergite about 1.7 as long as wide, about 1.1 

 as long as second tergite; second tergite about 1.1 as long as wide, 

 about 0.7 as wide at base as at apex; third tergite polished, its tubercles 

 rather prominent, covered with moderately coarse punctures whose 

 interspaces are about equal to their diameter; ovipositor sheath about 

 1.5 as long as front wing; tip of lower valve of ovipositor as in D. 

 imperator (fig. 330, g). 



Black. Clypeus and mandible more or less stained with ferrugi- 

 nous; scape and pedicel fulvous to brown or black in front; under 

 side of flagellum dark brown; palpi stramineous or the labial palpus 

 often brown; tegula white; hind corner of pronotum fulvous; coxae 

 and femora fulvous, the apex of hind femur infuscate and its extreme 

 apex fulvous; front trochanters whitish; front tibia and tarsus pale 

 fulvous; middle trochanters pale fulvous, the second trochanter the 

 paler; middle tibia and tarsus fulvous, the base of the tibia yellowish 

 fulvous and the tarsus tinged with brown; hind tibia and tarsus 

 reddish brown to fuscous, the basal 0.2 of the tibia fulvous. 



The male of this species has the scape and pedicel entirely white 

 in front and the propodeum without median carinae. The female 

 has only two ridges on the lobe of the lower valve of the ovipositor and 

 the abdomen strongly tapered basally, polished, and with moderately 

 coarse punctures. 



We have two females from Japan which may represent a subspecies 

 or a distinct species. They have the coxae black and some additional, 

 less conspicuous, color differences. 



The type of Ichneumon pterelas Say is destroyed. The original 

 description agrees with D. pterelas as determined here, and probably 

 as well with some others. We hereby restrict the name to the species 

 described as D. pterelas above.
