Philoyithus.] staphylinid^. ^ 2G3 



P. addendus, Sharp. Shining black, witli the elytra bronze, brassy 

 or with a more or less pronounced greenish rcllection ; head with the 

 temples more punctured than in the preceding, as broad as thorax in 

 male, plainly narrower in female; antennae with the penultimate joints 

 transverse, but not so strongly as in either of the two preceding species ; 

 the thorax also is slightly shorter and less visibly impressed at the sides; 

 the elytra are more brassy than in P. 2^'>'0-'^inius, and, together with the 

 hind body, are punctured much as in that species ; the male has the 

 seventh ventral segment less deeply emarginate and the membranous 

 space behind the emargination broader, and the sixth vential segment 

 shows very little trace of the sinuation which is very evident in tlie 

 allied species. L. 10 mm. 



In cut grass, dead leaves, &e. ; rare ; Coombe Wood, Surrey (Rye); New Forest 

 (Power); Hastiiigs (Butler); Repton, Burton- ou-Trent (W. Garneys) ; Kuowle, Slier- 

 wood Forest, and Wickeu Fen {\\ . G. Blatcb) ; Nortliuniberlaud district (Bold) ; 

 Scotland, very local, Solway, Forth, and Tay districts; Ireland, Killarney. 



P. carbonarius, Gyll. {nee Er., tenuicornis, Muls. et Eey, 2^unc- 

 tiventris, Jans. Ent. Ann. 1863, 82, nee Kraatz). Shining black, with 

 the elytra coloured as in P. -proximus (succicola, Thoms.), which is the 

 old carbonarius of Dr. Power's and other collections ; from all the pre- 

 ceding species, however, it is easily distinguished by having the antennae 

 rather longer, with the penultimate joints not, or scarcely, transverse ; the 

 elytra are rather finely and thickly punctured, and the punctuation of 

 the hind body is somewhat diffuse, but in these points it does not differ 

 materially from the two preceding species ; in the male the emargination 

 of the seventh ventral segment of hind body is less deep, and there is hardly 

 any smooth membranous space behind, and the sixth segment is quite 

 ezitire ; the head in both sexes is also smaller. L. 9-2-11 mm. 



In decaying vegetable matter, fungi, cut grass, haystack refuse, under moss, &c. ; 

 local ; London district, not uncommon ; Hastings ; Repton ; Tewkesbury ; Birmin<>-- 

 ham district; Shropshire; Liverpool; Manchester; Northumberland district, rare j 

 Scotland, local, not common, Solway and Forth districts, 



Mulsant and Rey abolish Gyllenhal's carbonarius, on the ground that 

 the insect descril)ed by him (Ins. Suec. ii., 319, 35) is not identical with 

 this species ; the name, however, is retained by Heyden, Reitter, and 

 Weise. 



P. temporalis, Eey = xDunctiventris, Kraatz nee Jans., an insect 

 which has given rise to some confusion, appears not to be a British iusect 

 at all ; it is rather closely allied to P. iennicornis, Rey, but dilfers in its 

 more coarsely punctured head and generally broader and more thick-set 

 form, &c. 



P. atratus, Grav. Somewhat narrower than the average specimens 

 of the four preceding species, shining black, with the elytra black bronze 

 with a bluish or greenish reflection ; head somewhat orbicular, more sub- 

 quadrate in male than in female ; antennse long with penultimate joints
