12. Q. maurus Sahib. 



(Sahib. Ins. Fenn. I, 317; Erichs. Jen. Spec. Staph. 551; Janglb, 

 Kaf. M. II, 4C0 - fagsti Thorns. Skand. Col. IX, 161; Muls. et Rey 

 Br^vlp. 1877, 494). 



Very closely allied to mesomelinus . from which it differs by the 

 following characters: 



As a rule it is somewhat smaller, narrower and more slender; the 

 color is more uniform and deeply black, only the tarsi and fore-tibiae 

 brownish; elytra with more scattered and robust punctation, and in 

 the O the abdominal sixth ventral joint is at tip more deeply emar- 

 ginate, also the posterior margin of fifth ventral joint is at middle 

 feebly emarginate and smoothened. L. 7-9 mm. 



Local and rare or very rare (Silkeborg, Tisvilde, Hiller/d, vici- 

 nity of Copenhagen). At the first mentioned place it is more often 

 beaten down from the blooming hawthorn (E. Petersen), also found in 

 hollow trees, under leaves, and at fungi; distributed in the entire 

 Middle and North Europe. 



13. Q. xanthopus Er. 



(Erichs. Kaf. Mk. Br. I. 487; Jen. Spec. Staph. 527; Kraatz Ins. 

 D. II, 495; Thorns. Skand. Col. II, 175; I.iuls. et Hey Br^vip. 1877, 

 521; Jang lb. Kaf. M. II, 4C0). 



From the closest allied, preceding species, it is easily divided 

 by its yellowish-red antennal base, and legs. 



Pitch-black or pitch-brown, glistening; head and pronctum with 

 specular shine; elytra and the abdomen finely haired; posterior mar- 

 gins of abdominal joints, the brown antennal base, mouth-parts, and 

 legs yellowish-red. In the teneral animals pronotum and elytra are
