From T. mellyi and T. gestroi this species may easily he known 

 by the sculpture of the elytra, and from T. tubereulata also by the 

 broader pronotum and more gibbose elytra.

Elongate, parallel-sided, gradually but not strongly widened, 

 and not strongly gibbose behind ; in general form much resem- 

 bling T. granulifera, var. rugosa, Chaud. ; colour black : antennae 

 with the 3rd and 4th joints more or less ringed with red ; femora 

 red, except at apex, tibiae and tarsi pitchy black or brown ; frontal 

 sulci very deep, with the space between smooth and slightly raised, 

 orbital striae well marked; pronotum glabrous or almost glabrous, 

 parallel-sided to about middle and from thence very gradually 

 contracted to the apical constriction : elytra strongly, evenly and 

 rugosely shagreened (much more coarsely than in T. coriacea), 

 the rugosity being more evident at base, and the sculpture being 

 less pronounced before apex, and very much less marked at the 

 extreme apex ; underside smooth. 



Length 18-20 millim.

Larger than the preceding spe- 

 cies which it much resembles in 

 other respects ; head with the sulci 

 h between the eyes very strongly 

 * marked, and the orbital stria) varia- 

 ble but usually distinct ; pronotum 

 S broader and more ample, with the 

 I contraction before the apical con- 

 J striction rather more marked ; 

 ^ elytra less abruptly narrowed be- 

 J hind and not so strongly or rugosely 

 J sculptured ; legs pitchy red, with 

 I the tibiae and tarsi darker. 

 Length 22-24 millim.

Chaudoir, in his original descrip- 

 tion, compares this species in detail 

 with T. altera, from which it is

(I. c.) says that it may easily be dis- 

 tinguished by the coarse and thick sculpture of the posterior portion
