A rather flat and broad, posteriorly broadened, winged species, in 

 relation to the following inter alia easily identified by the form and 

 longer elytra etc. (Fig. 180). 



Black or brownish-black, glistening; the thorax naked, abdomen fine- 

 ly and sparsely haired; pronotum and elytra most often reddish-brown, 

 more rarely blackish-brown with lighter margins, sometimes entirely yel- 

 lowish-brown; antennae, mouth-parts and legs reddish-yellow. 



The head (see above) with scattered and uneven, rather coarse punc- 

 tation, its grooves before the ocelli of vertex deep, interval between 

 grooves often foveate, impressions across base of antennae strong, anten- 

 nae long and slender, -(Page 601) all their joints longer 



than broad. Pronotum is somewhat narrower than elytra and hardly broad- 

 er than long, with anteriorly rounded, posteriorly more linear sides and 

 with rounded off corners, dorsum slightly convex, coarsely and somewhat 

 unevenly punctated with a few scattered, smooth places, on sides before 

 middle foveiform impressed, and side-margin from the fovea to hind cor- 

 ner narrowly set off. The elytra are approximately twice as long as pro- 

 notum, distinctly broadened posteriorly, with coarse and rather dense, 

 at middle and nearest the suture row-formed punctation; abdomen broad 

 with broadly set off, upturned side-margins, indistinct scattered punc- 

 tation or nearly smooth. L. 4.5-5.5 mm.
