Two specimens found by Mr, Richardson have been 

 presented to the Museum by Mr. F. D. Godman. The 

 species seems to closely resemble T. jundistriatus, Kuw., 

 which is intermediate in size between it and T. suhopacus, 

 Bates. In addition to its considerably larger size, it 

 differs by the deep channel upon the posterior part of the 

 cephalic horn, the absence of punctures upon the scutellum 

 and the different form of the prosternal process. The 

 median part of this is broad, parallel-sided, and strongly 

 produced behind. In front it is deeply grooved at the 

 sides and the median part is coarsely rugose. The meso- 

 sternum is quite smooth and shining in the middle and 

 the metasternum, as in T. junctistriatus, Kuw., is hairy at 

 the sides, wdtli very large confluent punctures near the 

 hind angles.

This is very near V. tuherculifrons, Kuw., from the 

 Amazon region, and indeed the short description of that 

 species applies also to this except for its rather smaller 

 size and the fact that the sides as well as the middle of
