82 STAPHYLINID^. 



under-side testaceous, metathorax smooth and almost impunctate, 

 abdomen alutaceous, reflexed margin of elytra finely punctured. 

 L. 4-4| mm. 



It comes nearest to O.fuscum, Grav., from which species it may be 

 at once known by its more parallel shape, and more fine, distinct but 

 diffuse punctuation, and lighter colour. The under-side is also much 

 less punctured. The thorax is considerably less transverse, and is more 

 narrowed in front. It is a brighter insect than either fvscinn or 

 piceum, Gyll., the latter species being larger, broader, more convex, 

 more strongly punctured, and with thicker antennte and palpi. 



Taken under sedge-stack refuse in Wicken Fen by Mr. Donisthorpe 

 and Dr. Nicholson, and subsequently in some numbei-s by Mr. Here- 

 ward Dollman, some fifty specimens being taken in all. It is 

 remarkable that such a distinct species should not have been detected 

 before. 



ORO CHARES, Kraatz. 

 Orochares, Kraatz (Naturgeschichte der Ins. Deutsch, ii. 955). 

 This genus was founded by Kraatz for the reception of the species 

 described below, which is the Deliphrum angustatum of Erich son. The 

 genus is very closely allied to Delijyhritjin, Er., and scarcely differs from 

 it except in having one of the mandibles toothed in the middle, and in 

 the general shape of the head and thorax. It is also allied to Arpedmm, 

 Er., in one or two points, but has a different facies. 



O. angustatus, Er. (Gen. et Spec. Staph. 874). Of rather slender 

 build, black, shining, with the elytra fuscous or f usco-testaceous ; head 

 long, produced before the eyes, with two distinct and deep roundish 

 impressions between the eyes, and a transverse furrow in front of these ; 

 antennae long and slender, gradually but not strongly thickened towards 

 the apex, blunt, with the base reddish-testaceous ; thorax not much 

 broader than the head, but much narrower than the elytra, about as 

 broad as, or a little broader than long, truncate before and behind, 

 with the sides slightly rounded and all the angles obtuse and sub- 

 rotundate, sparingly and very finely punctured ; scutellum distinctly 

 impressed ; elytra more than double as long as thorax, somewhat 

 depressed, ratlaer thickly and finely, but distinctly, punctured, the 

 punctures being more or less plainly arranged in rows, at all events in 

 •certain parts, extreme apical margin light testaceous ; legs testaceous or 

 reddish-testaceous ; abdomen very shiny, smooth, and scarcely visibly 

 punctured, with the apex acuminate. L. 3| mm. 



Leverstock Green, Herts. : one specimen taken by Mr. Piffard 

 hibernating in November at the roots of rushes in a disused clay pit. 

 Dr. Joy has also taken it near Bradfield. It has been recorded from 

 Germany and France, but appears to be very I'are. Fauvel (Favme 

 Gallo-Rhenane, Staph, p. 100) says it is found in dung and in i-otten 

 vegetables, and also on flowers, on plains, and on mountains from 

 November to early spring. Ganglbauer also records it from North
