(Fabr. Syst. Ent. 267; Srichs. Kaf. Mk. Br. I, 497; Jen. Spec. 

 Staph. 555; Kraatz Ins. D. II, 810; Thorns. Skand. Col. Ill, 144; Mule, 

 et Rey Drevip. 1879, 2; Janglb. Kaf. If. II, 602). 



The body (Fig. 153) is rather square, broad and robust; the head 

 large, porrect, not constricted behind, with rounded temples, rather 

 protruding eyes, very short clypeus, angularly incised labrum, far 

 protruding, robust, distally strongly broadened and somewhat flatly 

 depressed antennae; maxillary palpi normal, but the last joint of la- 

 bial palpi very broadly axe-shaped or semicircularly dilated (Fig. 152). 



Pronotum narrower than elytra, slightly narrowing and entirely round- 

 ed off posteriorly, posterior margin and sides finely marginated; el- 

 ytra longer than pronotum, and with impressed suture-stripe, prominent 

 humeral corners and rather equal posterior margin; abdomen rather short 

 and broad with elevated, broad side-margins, posteriorly rounded taper- 

 ing; tibiae not spiniferous, but with short bristle-hairs; all tarsi 

 5-jointed, the first joint short, the claw-joint almost as long as the 

 preceding joints together. 



Oxyporus species live both as larvae and mature beetles in fungi; 

 2 species, distributed in North and Middle Europe, are also found in 

 this country. (Fig. 152. Labial palpi of Oxyporus rufus Linn.).
