I have not seen the type of Saussure's species, but I think his 

 name applies to this form. The maxillary palpi of T. trifidus, 

 however, do not seem to differ from those of T. carinatus, but I 

 have not been able to dissect the mouth of either species.

Saussure's descriptions of the sexes of this variable species are 

 sufficient. It is very nearly allied to T. trifidus Westw.

(J. Clypeus strongly convex, broadly truncate at apex, sparsely 

 punctured, with a carina from base to apex. Head closely punc- 

 tured; interantennal carina narrowly V-shaped, produced at apex 

 into a minute tubercle at base of clypeus. Thorax shining and 

 rather sparsely punctured; scutellum large and broadly rounded 

 at apex. Median segment finely and closely punctured. Abdo- 

 men elongate, flattened above and beneath, very minutely punc- 

 tured, apical margins of the segments very narrowly depressed. 

 Hypopygium short, unarmed. 



$. Head much broader than long, rounded posteriorly, smooth 

 and shining. Thorax sparsely punctured ; pronotum much 

 broader than long, subconcave above, slightly narrowed poste- 

 riorly, the anterior margin straight with a slight elevation in 

 the middle. Median segment closely and finely punctured, short 

 and obliquely truncate posteriorly. Abdomen smooth, with a 

 few scattered punctures; apical margin of first segment not
