 (Long. Corp. | — 1 lin.) 



Oxyt. corticinus. Gravenhorst. — Steph. Catal. 294. No. 3204. Tro. corticinus. 

 Steph. Nomen. 2d edit. col. 106. 



Black, somewhat opaque, very thickly punctured : head convex ; mouth 

 pitchy red, pubescent : thorax with the anterior angles reflexed, the disc 

 convex, very delicately, but thickly punctured, with two abbreviated, some- 

 what bent foveae in the middle : elytra with the shoulders prominent, above 

 depressed, pitchy-black and a little glossy : abdomen linear, shining, slightly 

 pubescent : legs pitchy-red, with the joints, apex of the tibiae and the tarsi 

 paler: antennae dusky-pitchy, with the basal joint reddish. 



Taken, but rarely, within the metropolitan district. 



Genus DXXXVI. — T.enosoma, Mannerheim. 



Antennae not geniculated, the basal joint stoutest, clavate, second short, obconic, 

 six following minute, rounded, three next rather larger, suborbiculate, the 

 terminal one being acuminated. Pi//p2 maxillary with the penultimate joint di- 

 lated, thick, the apical one small, subulate : labruni transverse : AeaJ rounded, 

 unarmed, wider than the thorax, which is narrowed behind : eyes prominent : 

 body linear, slender: coleoptra depressed, broader than the thorax : abdomen 

 obtuse : legs short, unarmed ; tarsi simple, five-jointed, the terminal joint 

 as long as the others united. 



The small species contained in this genus were originally included 

 in the extensive genus Aleochara, from which Mannerheim removed 

 them ; they may be known by having the tarsi distinctly five-jointed, 

 the terminal joint of the maxillary palpi small, subulated, &c. : — they 

 inhabit fungi, putrid wood, and such-like objects. 



Sp. 1. pusillum. Nigrum, nitidulum, subtilissime punctulatum, antennis elytris 

 pedibusque testaceis, thorace sub-bifoveolato. (Long. corp. 1 lin.)
