6. Holotrochus smithi, sp. n. 



(Fauvel, in Utt.) 



Black, shining ; posterior margins of abdominal segments, 

 legs, and antennas reddish testaceous ; margins of thorax and 

 elytra sometimes obscurely red. 



Length 3 3-3' 5 mm. 



Very similar to H. marginatus, Slip., in size and general 

 appearance ; but distinguished from it by the longer thorax, 

 not bordered at the base, the fine but distinct reticulate 

 ground-sculpture, and the finer and more obsolete punctura- 

 tion of the head and thorax, and the impunctate shagreened 

 scutellum. From H. minor, Fvl., it differs by its larger size, 

 the ground-sculpture, and much finer and more obsolete 

 puncturation of the head and thorax, and impunctate 

 shagreened scutellum ; and from H. cylindrus, Er., by its 

 shorter and broader thorax and elytra, more distinct ground- 

 sculpture of both the latter, and the impunctate shagreened 

 scutellum. 



Head narrower than the thorax, truncate anteriorly, verv 

 finely and very sparingly punctured, with a fine reticulate 

 ground-sculpture. Antennae with the first joint stout, 

 second as long as, but stouter than third, fourth and fifth 

 globose ; fifth slightly, sixth to tenth more strongly trans- 

 verse. Thorax about a third broader than long, a little 

 wider at the anterior angles, very gradually and slightly 

 narrowed behind. Sculpture as on head. Elytra as long as, 

 but narrower than, the thorax, transverse, without visible 

 puncturation, but obsoletely shagreened. Abdomen im- 

 punctate, shagreened.
