ICHNEUMON-FLIES — GELINAE : MESOSTENINI 351 



femur rather light bro\vii; hind tibia and tarsus dark brown; wings 

 faintly infuscate; abdomen dark ferruginous, the basal 0.7 of its first 

 segment black and tergites 7 and 8 fuscous. 



Redescribed from the type. No other specimens are known.

Figure 388 



Front wing 3.7 to 5.6 mm. long; clypeus small, very strongly con- 

 vex, its apical margin weakly arcuate; mandible small; temple rather 

 strongly convex; cheek of moderate length, with coarse, strong, adja- 

 cent or subadjacent punctures and usually also with some horizontal 

 wrinkling that partially obscures the punctures; occipital carina 

 strong and sharp but not elevated as a lamella; second segment of fla- 

 gellum about 2.0 as long as wide in male, about 2.6 as long as wide 

 in female (averaging shorter than in any other species) ; thorax short 

 and stout; notaulus usually distinct and sharp but sometimes indis- 

 tinct, about 0.18 as long as mesoscutum; punctures on mesopleurum 

 rather coarse, strong, separated by about 0.3 theu* diameter; propo- 

 deum rather short, in female the apical carina broadly interrupted 

 medially, sublaterally forming a broad, rudimentary crest; hind femur 

 of male about 4.8 as long as deep, of female about 4.5 as long as deep; 

 sides of areolet usually rather strongly convergent forward; nervulus 

 beyond basal vein by about 0.28 its length; nervellus broken near its 

 lower 0.42; petiole short, flattened above, with rather distinct dorso- 

 lateral and ventrolateral longitudinal ridges, its sides with fine, weak 

 rugulosity in male, in female almost smooth; first sternite with fine, 

 weak longitudinal wrinkling (best developed m male) and a tendency 

 to be bounded apically on each side by a weak carina that represents 

 lower edge of the tergite; second tergite subpolished, its hair sockets 

 separated by about the length of the hairs; ovipositor normal for the 

 genus. 



The small size, stout build, short flagellar segments, small, strongly 

 convex clypeus, convex temple, and very coarse, dense punctures on 

 cheek distinguish this species. 



There are three subspecies, as keyed and described below:

or whitish; flagellum of female entirely blackish; range: Rocky Mountains 



to Pacific Ocean 8a. semirubra puUa, new subspecies 



Hind basitarsus of male whitish, its basal 0.35 ± brown; flagellum of female 

 with a median white mark; range: Atlantic Ocean to Rocky Mountains.
