marked by a smooth line ; the punctures of the elytra are more 

 or less confluent, whereas iu T. coriacea they are separate, but 

 this does nob appear to be a very distinct character, and I am 

 inclined to regard the insect as merely a variety of the last-named 

 species.

Black, with a more or les 



distinct cyaneous, brassy or violaceous 

 reflection, especially in front : 

 underside sometimes brownish ; 

 elongate, narrower, more parallel- 

 sided, and less dilated behind than 

 in T. coriacea', labrum more or 

 less red ; head with the sulci and 

 the striae between the eyes strongly 

 marked, and with a distinct fur- 

 row at the base of the excavation ; 

 pronotum with distinct trans- 

 verse striation, more slender and 

 elongate than in the preceding 

 species ; elytra with strong, hori- 

 zontal, confluent rugose sculpture, 

 the interstices in the middle 

 forming more or less parallel 

 ridges in some specimens, but 

 variable, suture marked by a 

 smooth line ; legs long, more or 

 less red or pitchy red; underside 

 almost smooth, but sometimes 

 with distinct traces of striae on 

 the prosternum. 



Length 24-27 millim.

Var. rugosa, Chaud. 



This variety is distinguished by its more robust form, which is 

 more widened behind, and coarser sculpture. Dr. Horn is quite 

 right (Deutsche Ent. Zeitschr. 1892, p. 209) in regarding it as 

 merely a variety. There is considerable variation in the ordinary 

 specimens of T. granulifera.
