98 COLEOPTERA. 



Dr. Sharp records the existence of P. testaceus in his 

 British collection, adding Boieldieu's statement that it in- 

 habits temperate Europe, and is rather common in wheat 

 granaries. If I be right in referring Mr. Waterhoiise's 

 insect to this species, it may be noted that it is somewhat 

 allied to P. fur, but is smaller and shorter, with no tuft of 

 white pubescence at the back of the thorax, and the elytral 

 ashy markings almost entirely wanting, so that the insect 

 seems uniformly testaceous. The joints of its antennse are 

 also decidedly much shorter and comparatively broader. 



Mr. Wollaston says that P. testaceus occurs sparingly, 

 about houses and stores, both in the Madeiras and Canaries, 

 where it has doubtless become established accidentally 

 through the medium of commerce. It is unquestionably a 

 mere importation, or at the utmost naturalized from more 

 7iorthern latitudes.

Dr. Sharp notes the existence of this species in his own 



British collection ; I, also, find it in mine, and have observed 



it mixed with T. ferrugineum in that of Mr. Champion. 



Compared with the latter species, T. confusum is rather 



larger, broader and flatter, with the thorax more rounded 



outwardly in front, the front tibiae not so acutely produced 



externally, the elevated clypeal ridge carried further back 



along the eye, which, therefore, looks smaller ; the elytra 



more shining, with the minute interstitial punctures less 



regular, and the antennae with stouter and shorter basal 



joints, and gradually dilated towards the apex, instead of
