 slightly impressed transversely in the anterior part, with a broad, 

 central, longitudinal depression including a narrow, median groove, 

 a depression on each side of the base and the outer angle nearly 

 rounded, roughly punctured, the punctures very briefly setigerous ; 

 elytra moderately convex, rounded in the anterior angles, gradually 

 ampliated to a short distance from the apex, with the outer sides 

 moderately rounded, narrowly punctato-striate with the intervals 

 broad, equal, convex, and having one series of punctures on each side, 

 outer margin rugose and with a double series of broad punctures ; 

 under side and legs black, rugose and briefly pilose. Length 24-

Trlenogenius vicinus. 



Head shining ; labrum smooth ; apical part of palpi slightly 

 reddish ; head very closely and deeply punctured ; prothorax one- 

 third longer than broad, ampliated in the anterior part and narrowed 

 behind as in T. corpulentus ; elytra elongated, not much convex, 

 rounded in the anterior angles, gradually ampliated to a short 

 distance from the apex, but with the outer sides not hardly rounded, 

 narrowly striato-punctate with the third, fifth, and seventh intervals 

 narrow, smooth, carinate from the base to past the middle and 

 with one series of punctures on each side, the alternate intervals 

 convex, and with several series each of closely set, deep punctures. 

 Length 19 mm. ; wddth 7 mm. 



Closely allied to T. anthioides, Chaud., from which it differs mostly 

 on account of the alternate carinated intervals.

 anterior impression, as well as the posterior lateral ones, hardly 

 pronounced ; elytra gradually broadening from the base to long past 

 the middle, and also narrowed from there, the anterior angles 

 rounded, a little convex, narrowly punctato-striate, with the intervals 

 convex, equal, and each one with three series of closely set, more or
