Cylindrical, black, sliinin;^, witli a red band across the 

 elytra before the base. 



(^ . Head and rostrum opaque, latter robust, parallel and 

 carinate at the sides, obtusely pointed in front, ocular tubercle 

 well marked ; thorax eveidy punctured anteriorly and at the 

 sides, more sparsely and more finely punctured before the 

 scutellum, behind the neck are two small tubercles set 

 together, anterior angles reddish ; elytra sparsely punctulate, 

 punctures closest at apex and near the suture, before the base 

 there is a rather broad red band ; pygidiuni rugosely and 

 densely punctured ; prosternum carinated at the sides ; meso- 

 sternum arched in front, bistriate ; metasternum sulcate in 

 the middle anteriorly ; posterior tibiae triangular and dilated. 

 L. 3 mill. 



? . Head oj)aque, feebly punctured, ocular tubercle very 

 small ; thorax evenly punctate throughout ; pygidium rather 

 closely punctured, moderately produced and obtuse at the 

 apex. L. 3^ mill. 



This species resembles T. placjiatus^ but it is more robust, 

 with the rostrum broader and extending laterally in the males 

 outside the carinse; the two thoracic and the ocular tubercules 

 also distinguish it from the preceding species, and in the 

 female the pygidium is much shorter.

The above names represent the sexes of one species, and I 

 propose to retain tlie first for it, as Marseul gave the female 

 the precedence in his paper, and also because I think it likely 

 that Marseul's leading idea at the time of writing his descrip- 

 tions was to dedicate a species to his friend from whom the 

 si)eeimens came. I think it well to adopt the name of Try- 

 peticus suggested by Marseul for the eastern forms of Try- 

 pana'iis which have a prosternum truncate at both ends ; and 

 I have done so in this paper.

jj. Cylindrical, narrow, piceous, angles of the thorax 

 rounded off anteriorly, and these, with the margius of the 

 elytra, arc testaceous ; head transversely convex before tiie 

 neck, with a straight stria between the eyes which divides 

 the forehead from the rostrum ; tlie eyes are prominent, almost 

 wholly seen from above, and nearly circular in outline ; the
