male has no spine on the sixth ventral segment as in T. novarce, 

 and the shape of the clypeus is different.

Saussure's description is good. In the two male specimens I 

 have seen, the anterior portion of the clypeus is longitudinally

191. T. pseustes, n.sp. 



(J. Clypeus delicately longitudinally striate-punctured, pro- 

 minent at base, then deflexed to apex and broadly truncate. 

 Head, thorax and median segment very finely and closely punc- 

 tured, head and thorax above with thin fulvous pubescence, 

 Scutellum rather long, with a delicate, longitudinal, median carina. 

 Median segment longer than broad, with a short longitudinal 

 sulcus on each side at apex. Abdomen elongate, finely and closely 

 punctured; segments 2-4 with an impressed transverse line near 

 base. Dorsal plate of apical segment produced, narrow at apex 

 and longitudinally striated. Hypopygium transversely striated 

 above, with a spine on each side near basal angles, thence pro- 

 duced and elongate-triangular, with a minute apical spine. Sixth 

 ventral segment with a spine on each side at apical angles. Black; 

 mandibles and clypeus yellow; legs, except coxae and trochanters, 

 ferruginous. Wings hyaline tinged with yellow, nervures fusco- 

 ferruginous. Length 14 mm. 



$. Head coarsely and sparsely punctured, subrectangular, 

 rounded at posterior angles, a little broader than long, 

 and slightly convex. Thorax sparsely punctured; pronotum
