long, and exhibits distinctly the genei'ic character of raised lateral 

 ridges with oblique ridges between. The thorax is more thickly 

 tuberculated than in T. verrucosus, while the tubercles on the elytra 

 are not so conical or pointed as in that species. The elytra are 

 mucronate. 



The two specimens of this insect in my possession are of the 

 same sex, and I am in doubt as to whether they are male or 

 female, though most probably the former. The anal ventral 

 segment is very slightly excavated, and has two minute tubercles 

 at its apes, with a semicircular emargination between them.

This is not unlike the last described species about the head 

 and rostrum. The tubercles of the thorax are, however, smaller, 

 and furnished with longer " setse." The elytra have a row of 

 about six elongated tubercles near the suture, then a series 

 of rather irregular small hemispherical ones ; then again a row 

 of five or six elongated ones ; and then two rows of round and 

 smaller ones. The sides are coarsely punctured and very rugose, 

 and the suture has a row of granules on each side, and is 

 mucronate and slightly dehiscent. 



The only specimen I possess — probably a male — is slightly 

 excavated, and emargiuated at the apex of the last ventral 

 segment.
