2 • Not so slenderly made as the majority of the species of this 

 genus. Head, thorax, and abdomen densely pubescent, the pubes- 

 cence lontJ and soft on the clypeus, the front cheeks behind the 

 eyes, on the pronotum, the fronf, .sides, and apex of the mesonotum, 

 the scutellum, postscutellum, median segment, and pleura?, shorter 

 and less dense on the abdomen ; the le2;9 pilose ; the head and 

 thorax underneath the pubescence moderately puncrured: the 

 disc of the mesonotum and the middle of the median segment 

 smooth and shining ; the latter long, with a gradual slope to the 

 apex, and a short medial longitudinal groove widening about mid- 

 way into a deep shining broad hollow, and another longer wider 

 fovea on the slope of the segment ; clypeus long, subtriangular, 

 convex, the apex broadly rounded ; the front with a small tubercle 

 above the base of the antennae. Black, the pubescence golden : 

 the mandibles, the apical margin of the clypeus, the scape and 

 basal four joints of the flagellum of the antennae, the posterior 

 margin of the pronotum, the tubercles, the petiole of the abdomen 

 benfath, the base of the 2nd and 3rd, and the apical margins of 

 the 3rd, 4th, and 5th segments above pale testaceous red ; the legs 

 testaceous, variegated with black ; wings hyaline and iridescent, 



nervures and tegular testaceous. 



(J similar, the abdomen more or less rufo-fuscous with the apex 

 pale.

5 . Closely resembles T. bicohr, but is constantly larger, 

 the front above the base of the autenufe bears a small tub rcle 

 instead of a carina, the medial furrow on the medinn segment is 

 broader and not interrupted in the middle, and the head and 

 thorax are more densely pubescent and pilose. 



c? . Differs from the female in having the antennae black beneath, 

 not rufo-fulvous, and a fuscous patch at the base of the 2nd 

 abdominal segment above.
