scape long, extending slightly beyond the top of the head. Thorax : 

 llie pro- and mesouotum convex, obliquely sloping backwai'ds ; the 

 pro-mesonotal suture distinct. Viewed in protile, the thorax is 

 <^inarginate at the nieso-inctanotal suture, the basal portion of the 

 metanotum short, horizontal, much shorter than the obliquely 

 truncate apical portion ; legs stout and long. Pedicel and abdomen 

 niueh as in T. alhipes, the lattei- slightly more massive.

2iaH;/e. Both hemispheres. 



^ . Head with the mandibles scutiform, the occiput broadly 

 iransverse; mandibles triangular, dentate, the masticatory and 

 outer margins subequal ; clypeus broad, its anterior margin 

 narrowly incised in the middle (not incised in the Indian species); 

 maxillary 6-. labial palpi 4-jointed ; frontal area obsolete ; antenna; 

 liliform. 12-jointed; eyes comparatively large, lateral, placed a little 

 to the front. Thorax narrower than tlie head ; the proiotum 

 ■comparatively convex and a little broader than the rest of the 

 thorax; pro-meso- and meso-metaiiotal sutures both distinct, the 

 pro- and mesonotum subequal in length ; the basal portion of the 

 metanotum very short, the apical portion broad, obliquely truncate, 

 slightly concave ; legs comparatively long and shmder. Pedicel 

 with the node flat, strongly inclined to the front ; abdomen oval, 

 the basal segment gibbous, overhanging the node, and with an 

 almost obsolete fovea on the anterior face for the reception of the 

 node of the pedicel. 



5 . Kesembles the ^ , but is larger, with a shorter and com- 

 jiaratively broader head, and much larger eyes ; ocelli minute but 

 distinct ; clypeus not incised anteriorly in the middle. Thorax 

 Aery massive, broader than the head; the pronotum depi'essed, 

 vertical, not forming part of the dorsal surface ; mesonotum large, 

 convex, gibbous in front ; scutellum broad and long ; postscutellum 

 transverse ; median segment or metanotum as in the ^ , but propor- 

 tionately much larger ; wings ample, fore wing with only one closed 

 cubital cell. Pedicel and abdomen as in the ^ , but much larger. 



(5. Resembles the 5, but the head is almost triangular, the 

 cheeks straighter, not so convex, the mandibles narrov\-, not 

 dentate, but with the apex acute ; the eyes are extraordinarily 

 large and convex, and the ocelli minute and not very distinct. 

 Thorax similar to that of the $ , but the median segment or 

 metanotum is roundly couacx. Pedicel : the node rounded above,
