ICHNEUMON-FLIES — GELINAE : MESOSTENINI 233 



Female type: Front wing 7.5 mm. long. Generally similar in 

 structure to T. recurvatus except that apical carina of propodeum is 

 a little weaker, hind femur about 7.0 as long as deep, second recurrent 

 vein is moderately sinuate, dorsolateral and median longitudinal cari- 

 nae of fu'st abdominal segment a little stronger, ovipositor sheath 

 0.91 as long as front wing, and apical part of ovipositor, especially 

 the tip, a little thicker and less distinctly upcurved. 



Black. Front orbit, hind orbit, and stripe across top of eye, 

 narrowly yellowish white; spot in center of clypeus, short submarginal 

 stripe on upper part of pronotum, hind corner of pronotum, and 

 subtegular ridge, narrowly yellowish white; front and middle femora 

 dark brown, their tibiae and tarsi brownish fulvous; hind femur 

 ferruginous; hind tibia and tarsus brown, the tarsal segments 2-4 

 paler; wings infuscate; abdomen ferruginous. 



Female paratype: Similar in general to the type but the white 

 markings restricted to a very narrow stripe on hind orbit. The front 

 wing is 9.0 mm. long and ovipositor sheath 0.71 as long as front 

 wmg. We did not compare this paratype directly with the type. 

 Possibly it is not the same species.
