402 Mr. G. Lewis on 



Cylindrical, black, shining, with 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, ocidar tubercle 

 well marked ; thorax evenly 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 ; pygidium rugosely and 

 densely punctured ; prosternum carinated at the sides ; meso- 

 sternum arclied in front, bistriate ; metasternum sulcate in 

 the middle anteriorly ; posterior tibiae triangular and dilated.

 closely punctured, moderately produced and obtuse at the 

 apex. L. 3^ milL 



This species resembles T. pJagiatus^ 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 tlie sexes of one species, and I 

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

 tlie precedence in his paper, and also because T 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 

 specimens came. I think it well to adopt the name of Try- 

 peticus suggested by Marseul for the eastern forms of Try- 

 panceus which have a prosternum truncate at both ends ; and 

 I have done so in this paper.

(J. Cylindrical, narrow, piceous, angles of the thorax 

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

 elytra, are testaceous ; head transversely convex before the 

 neck, with a straight stria between the eyes which divides 

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

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