Aleochara riifescens, Steph. lUust., Mand., v., 128. — Bolito- 

 cliara circellaris, var. lb. Manual, No. 2784. 

 Closely allied to U. circellaris, but smaller, head and thorax 

 shorter, the elytra more deeply punctate, not quite so depressed, 

 the abdomen somewhat wider towards the apex, the penultimate 

 segment of the abdomen above in the male, with a short elevated 

 shining ridge, instead of a prominent tooth; the colours also 

 brighter. Shining, nearly glabrous. Antennae slightly longer 

 than the head and thorax, gradually thickened exteriorly, not so 

 stout as in H. circellaris, dusky, ferruginous, the base and apical 

 joint paler, or in dark specimens, rufous only at the base, the 

 joints short, compact, the last rounded, abruptly acuminate. 

 Mouth and palpi testaceous. Head short, closely applied to the 

 thorax, narrowed anteriorly, black, finely punctate. Thorax 

 about the breadth of the elytra, somewhat orbicular, the apex 

 truncate, sides and base nearly equally rounded, bright rufous or 

 concolorous, convex above, thickly and finely punctate, the base 

 obsoletely foveolated. Elytra short, about the length of the 

 thorax, and somewhat broader, scarcely depressed, as a whole, 

 surface, especially in the male, deeply depressed behind the 

 scutellum, and longitudinally on the disk behind the shoulders 

 thickly, rather strongly, and distinctly punctate, black. Abdomen 

 rather narrowed towards the base, and becoming wider towards 

 the tip, the apex abruptly narrowed, first four segments thickly 

 and finely punctate, but more distinctly than in R. circellaris, 5th 

 smoother, obsoletely punctate, the male marked with a raised 

 shining ridge in the middle, which is nearly one half of the length 

 of the segment; the apex, and sometimes the two basal joints 

 rufous. 



In Polypori, and under bark, but never in moss. Ravensworth 

 woods, Gibside, &c. March — November. 



In some collections, this is named Bolitochara inquinula.
