(Steph. 111. Brit. V, 298; Janglb. Kaf. I/.. II, 588. - plantaris 

 Erichs. Kaf. Mk. Br. I, 562; lien. Spec. Staph. 722; Kraatz Ins. D. II, 

 781; Thorns. Skand. Col. II, 233; Rey BreVip. 1884, 220). 



Very closely allied to both the preceding species, from which it 

 however is easily separated by entirely yellow maxillary palpi, and by 

 reddish-yellow tarsi. 



Black, lead-gray glistening, with dense and rather long, prostrate, 

 silver-white glistening hair; antennae reddish-yellow, their first joint 

 black, the club most often brownish; maxillary palpi yellow; legs black 

 with reddish-yellow tarsi. 



The head is broader than in binotatus. broader than pronotum, hard- 

 ly as broad as elytra, rather fine and dense punctation and with two 

 flat forehead grooves, separated by a distinctly convex, somewhat glist- 

 ening interval, (Page 515) the antennae 



rather short; pronotum much narrower than elytra, oblong, rather finely 

 and densely punctated, the surface extremely finely shagreened, and with 

 a feeble side-impression behind middle; elytra nearly lj times as long 

 as pronotum, punctated and snagreened as this; abdomen finely and dense- 

 ly punctated, posteriorly tapering. L. 4.5-5 mm. 



In the O the hind tibiae are feebly undulated, without spine at tip; 

 abdominal third and fourth ventral joints are posteriorly slightly im- 

 pressed and feebly emarginated, the fifth not impressed, the sixth at tip
