groove; median lobe transversely rugose, more coarsely so on the 

 sides; lateral lobes and seutellum finely rugose. Propodeum deeply 

 reticulate, the spaces rather regular, nearly circular; entire thorax 

 almost without pubescence. Pleurae coarsely rugose-reticulate, finer 

 on the mesopleura above near the tegulae and on the base of the sides 

 of propodeum. Abdomen subshining, uniformly blackish; sheaths 

 of ovipositor tipped with white. Legs with the hind coxae coarsely 

 transversely rugose above and externally, finely punctate below; 

 hind tibiae less swollen than usual, but little thicker than the femora; 

 their tarsi stout, the first joint distinctly longer than the following 

 together, both the hind tarsi and their tibiae at tip conspicuously 

 clothed with golden pubescence. Radial cell broad, the radius sharply 

 bent upwards at its apical third; small discoidal cell almost as long 

 as its petiole. 



Of the species referred to this genus by Kieflfer, this comes closest 

 to T. abiiensis Cam. from India, from which it differs in its clear wings 

 and differently colored legs. It is also quite different from any species 

 of Gasteruption known from this region, aside from the generic differ- 

 ences which do not appear to be very clear-cut, at least when applied 

 to our American species.

9 . Length 7.5 mm., ovipositor 3 mm. Black; head below the 

 level of the antennae dark reddish brown ; antennae yellowish at base, 

 brown beyond: palpi piceous; tarsi brownish yellow; posttegulae 

 white, seventh and eighth segments of abdomen yellow; wings fuscous, 

 with a hyaline cross-band near the base and a hyaline streak extending 

 across from the base of the stigma; apex hyaline; veins black, stigma 

 white at base. Head seen from above, as wide as thick, full behind 

 the eyes, then roundly narrowed to the prominent posterior carina; 

 eyes rather large, as wide as the cheeks, the malar space two thirds 

 the length of the third antennal joint; eyes slightly emarginate oppo- 

 site the antennae; ocelli in a nearly equilateral triangle, posterior 

 ones nearer to one another than to the eye-margin. Mouth opening 

 gently concave above, the clypeus separated, with deep lateral foveae. 

 Face transversely rugose; front and vertex evenly transversely aci- 

 culate; back of head above middle of eyes horizontally aciculate, the
