Mus.), wherein the species is mentioned as being in Kirby's own col- 

 lection, and in those of Drs. Spence and Hooker. In the M.S.S. 

 Catalogue accompanying Kirby's Collection melanarius is referred to 

 as No. 7 in the section with margined abdomen and black legs ; and 

 the identical specimen labelled No. 7, and named melanarius, is to be 

 seen among Kirby's Staphylinidce, also in the British Museum, to which 

 Institution they were presented by the Entom. Society of London. 

 This insect agrees well with the description, and there can be scarcely 

 any doubt as to its identity with the subsequently described cinerascens 

 of Erichson, as it accords with the latter's description, with type sent 

 by Dr. Kraatz to the Brit. Mus., and with my own examples, which 

 are identical with a specimen belonging to Mr. E. Shepherd, also named 

 cinerascens, by Dr. Kraatz. 



Of similar colour and appearance to morio, \\ lin. Palpi black, the 

 first joint pitchy-testaceous. Head rather wider than the thorax, the 

 grooves not deeply impressed, with the interstice moderately convex. 

 Thorax decidedly longer than broad, rather narrowed behind, with no 

 trace of a dorsal channel, but very slightly depressed behind the middle; 

 thickly punctured, the interstices narrow and scarcely rugulose. 

 Elytra a trifle longer, and less closely punctured, than the thorax ; 

 the interstices nearly flat (but not so level as in S. morio) ; depressed at 

 the suture. Abdomen shining, with fine and rather scattered punctures. 



The difierences between this species and morio are pointed out 

 above ; from canaliczdatus it may be known by its more slender struc- 

 ture, and the absence of a thoracic channel ; and from biiphthalmus by 

 its narrower thorax, less strongly punctured elytra (the interstices of 

 which are scarcely, if at all, rugulose), and by the finer and more 

 remote punctuation of its abdomen ; it is also altogether more slender. 



Besides the above-mentioned examples this species has been taken 

 by myself in the London district, and by Mr. D. Sharp at Wimbledon ; 

 it is also in Dr. Power's collection, from the Fen district. 



Incrassatus, Erichson. 1| lin. About the size of huplithahmis, 

 from which it may be known by its narrower head, more ample elytra, 

 and thicker abdomen. Rather dull black ; palpi black with basal joint 

 testaceous. Head very narrow ; scarcely, if at all, wider than the 

 thorax. Thorax scarcely longer than broad, very closely and strongly 

 punctured, the interstices almost rugulose, and with a slight depression 

 behind. Elytra considerably wider and a little louger than the thorax ; 

 strongly and closely punctured, the interstices somewhat coarsely 

 " engine-turned," and with a large scutellar depression. Abdomen 

 (especially in the female) stout, shining, with the keels at the base of 

 the segments as in huphthalmus.
