narrow median groove and a basal impression on each side of the 

 groove, the median part of the base striolate ; elytra elongate, but 

 a little ampliated in the middle, broader than the prothorax, with the 

 shoulders acute, truncate obliquely behind, plane, narrowly punc- 

 tato-striate, with the intervals plane and covered with a very short, 

 silky pubescence, on the fourth interval is a broad, rounded sub- 

 median impression, and another past the middle on the third, and in 

 the posterior part on each side a transverse yellow patch extending 

 from the fifth to the eighth interval ; legs and tarsi black. Length 

 5 mm. ; width 2J mm.

The description of T. higuttatus applies almost entirely to this 

 species, the only distinctive characters being that the three basal 

 joints of the antennge are yellow instead of the first one only ; the 

 elytra are also a little more ampliated in the middle, the silky 

 pubescence is denser and more glittering, and the two dorsal round 

 impressions on each side are also broader ; the tibias are yellowish 

 instead of being black.

Head and prothorax metallic black, shining ; the three basal 

 joints of the antennae, palpi, and legs reddish ; prothorax smooth, 

 one-third broader than long, a little wider in the anterior than in the 

 posterior part ; the striolation of the median part of the base very 

 conspicuous ; elytra a little broader at the base than the prothorax, 

 with the anterior angles acute, slightly rounded below the shoulders, 

 with the outer sides nearly parallel, the posterior part obliquely 

 truncate, plane, narrowly and deeply striate with the intervals 

 plane, the third one with two punctures, bronze black, shining, 

 without any pubescence, and each one with a subhumeral broad 

 yellow band reaching diagonally from the sixth to the third stria, 

 and a posterior irregularly triangular one of the same colour above 

 the apex, and extending from the third stria to near the outer 

 margin ; under side piceous. Length 7 mm. ; width 3 mm. 



In one example the apex of the subhumeral diagonal band is 

 produced along the fourth interval in the direction of the supra- 

 apical patch.
