than long, broadly rounded at the apex ; median segment 

 rather closely punctured, the dorsal surface a little longer 

 than the scutellum and not divided from the oblique posterior 

 slope. Abdomen shining, microscopically punctured, with a 

 few larger punctures near the apex of the third, fourth, and 

 fifth segments ; first dorsal segment rather strongly depressed 

 on the apical margin ; second with four strong transverse 

 carinse, including the raised apical margin ; pygidium nar- 

 rowly elongate-ovate, pointed at the base, the sides forming 

 marginal carinse. Fifth ventral segment closely and deeply 

 punctured at the apex.

This is near T. iridipennis, 8m., but has the clypeus much 

 less strongly convex in the male. According to Smith the 

 female of iridipennis has only two transverse carinse on the 

 second segment, and the male hypopygium is truncate, not 

 emarginate. 



Unfortunately the types are lost_, having been in the 

 Bakewell collection.

(J. Clypeus scarcely convex, rather broadly truncate at 

 the apex. Antennae nearly as long as the head, thorax, and 

 median segment combined, slender, the apical joints a little 

 narrowed ; the interantennal prominence almost obsolete. 

 Head and thorax finely and closely punctured ; the pro- 

 notum short, slightly emarginate anteriorly. Median seg- 

 ment shining and almost smooth ; abdomen slender, sparsely 

 and shallowly punctured, the segments constricted at the 

 base. Seventh dorsal segment more coarsely punctured ; 

 hypopygium with a long apical spine, narrowed from the 

 base, with a small spine on each side at the base. Second 

 abscissa of the radius a little shorter than the third, second 

 recurrent nervure received at about one-fifth from the base 

 of the third cubital cell.
