ICHNEUMON-FLIES — GELINAE : MESOSTENINI 265 



Male: Front wing 8.0 to 12.0 mm. long; mesoscutum subpolished, 

 its punctures small, strong, separated by about 0.5 their diameter ; 

 apical transverse carina of propodeum absent medially, moderately 

 strong laterally; pleural carina below basal transverse carina com- 

 plete, moderately strong but rather irregular; hypostomal carina, 

 front edge of pronotum, and notaulus as in female. 



Ferruginous. Frontal orbit and mandible yello\vish fulvous; basal 

 5 to 7 segments of flagellum fulvous, darker above; beyond the fifth 

 to seventh segments of flagellum a pale yellow band, apicad of which 

 the flagellum is blackish; occiput, prosternum, prepectus, mesepimeron 

 except upper end, some sutural markings on thorax, often part or 

 most of side and under side of thorax, and basal 0.3 ± of third tergite, 

 black; coxae partly infuscate to mostly blackish; first trochanter of 

 middle and hind legs more or less infuscate; front and middle tibiae 

 yellow, fulvous below; tarsi yellow, their fifth segments bro^vn, the 

 basal 0.4 ih of fifth segment of hind tarsus yellow; wings colored 

 about as in female but usually a little paler and with indistinct darker 

 bands; base of first, second, and fourth tergites usually more or less 

 infuscate. 



Female: Front wing 8.5 to 11.5 mm. long; hypostomal carina distad 

 of occipital carina rather high, about 0.55 as long as basal width of 

 mandible, its apex weakly projecting beyond lower articulation of 

 mandible; epomia about 0.30 as long as height of pronotum; front 

 edge of pronotum with a moderate curve at its lower 0.35; mesoscu- 

 tum mat, its punctures very small, weak, separated by about 0.3 

 their diameter; notaulus moderately sharp, reaching about 0.35 the 

 distance to scutellum; apical transverse carina of propodeum sharp, 

 obsolescent or weak medially and next to pleural carina, sublaterall}^ 

 maldng a moderately strong crest; propodeum wrinkled near to and 

 apicad of its apical transverse carina; second tergite strongly mat, 

 with fine, adjacent punctures; ovipositor tip as in figure 329, c. 



Brownish ferruginous. Flagellum dark brown, with a pale yellow 

 band that covers about 6 segments; median part of occiput, marks on 

 thorax of variable extent (including at least some of the deeper su- 

 tures and at most these plus most of propodeum and sides and under 

 side of thorax), and basal 0.3 ± of third tergite, black; front coxa 

 sometimes weakly infuscate; middle and hind coxae and trochanters 

 faintly to strongly infuscate, sometimes largely blackish; hind tarsus 

 yellowish fulvous, darker at base and apex; wings rather uniformly 

 dark brown as in figure 343, the front wing often with faint darker 

 banding; base of first abdominal segment and basal 0.3 of second 

 tergite more or less infuscate.
