Head convex, smooth, with the usual impressions in front ; 

 palpi and antennae testaceous. Thorax nearly quadrate, a little 

 narrowed behind and with the hinder angles obtuse, more rarely 

 inclined to right angles, base usually broad and almost truncate, 

 the dorsal furrow strongly marked and met in front by a de- 

 pression curved so as to enclose a triangular raised space above 

 it, base with a large punctured fovea on each side. Elytra oblong- 

 ovate, sides very slightly rounded in some examples, but more 

 ovate and more dilated behind the middle in others, convex, 

 moderately striated, some of the exterior striae obsoletely punc- 

 tured ; legs pale testaceous. The colour is very variable, some- 

 times reddish testaceous or fulvous, pitchy red, or pitchy brown 

 or ferruginous with an obscure dusky oblong dash on each 

 elytron, the paler colours not being always indicative of a less 

 degree of maturity. It is also very variable in size. Length 

 lf-2j lines. 



T. brunnipes, Steph., is a dark individual of this species. The 

 true T. brunnipes, Sturm, is not found in Britain and is altogether 

 a different insect. 



This species is very abundant and generally distributed.

This species is about two-thirds the ordinary stature of fulvus, 

 and very small examples of that insect are liable to be confounded 

 with it. It is oblong-ovate, reddish ferruginous with the thorax 

 usually paler. Head smooth and very convex with a small round 

 fovea on each side in front ; antennae pitchy with three joints at 

 the base pale ; eyes black. Thorax nearly quadrate, more convex, 

 base with two deep fovese punctured within and on the edges, the
