334 staphylinidjE. [Stcjius. 



Ilf racombe, &c. ; Somerset; Barmouth; Matlock; Buxton ; Scarborough ; Cheshire ; 

 not recorded from the extreme northern counties of Eiighind, but it probably occurs, 

 as it is found in Scotland in the Solway, Tweed, Forth, and Clyde districts j Ireland, 

 near Killarney. 



S. proditor, Er. [rijxecola, Sahib.). A narrow, parallel-sided, and 

 somewhat cylindrical species ; black, moderately shining ; antennae 

 pitchy, basal joint, and base of second joint of palpi, testaceous ; head 

 large with very prominent eyes, strongly furrowed ; thorax oblong, 

 almost as broad as elytra, and of about the same length ; thorax and 

 elytra thickly and moderately, but not coarsely, punctured ; hind body 

 rather finely and thickly punctured, front segments with a small longi- 

 tudinal keel at base ; legs dark pitchy-black, or pitchy-red ; base of femora 

 lighter ; this species most resembles S. argus, but is darker, less pubes- 

 cent, with much shorter elytra, and more distinctly margined hind body ; 

 from S. nitens it may be distinguished by its duller appearance, shorter 

 elytra, and the absence of a dorsal channel on thorax. L. S^ mm. 



Male with the seventh ventral segment of hind body excised angularly 

 at apex, sixth deeply sinuate with a smooth depression behind sinuation, 

 terminated on each side by a slight keel. 



Rare; first taken at Finchley by Mr. E. W. Janson ; it is chiefly a fen species, and 

 has been found at Wicken, Horning, and Ranworth Fens, by Mr. Crotch, Dr. Siiarp, 

 Mr. Matthews, Dr. Power, and others. 



This species has the legs so dark that it hardly seems to belong to the 

 group in which it is placed ; at the same time it can hardly be classed 

 with the species in Avhich the legs are quite black. 



S. speculator, Er. (clavicornis, Scop., hoops, Gyll.). Dull black, 

 winged ; head rather strongly furrowed, antennae pitchy red with the 

 club dark, and the first two joints black, palpi testaceous ; thorax 

 oblong with sides moderately rounded, broadest in middle, rather strongly 

 and very thickly punctured, with obsolete central channel ; elytra as 

 long as thorax, strongly and closely punctured ; hind body rather shining, 

 closely and much more finely punctured than elytra ; legs testaceous, 

 knees and sometimes extreme base of femora narrowly darker, coxae 

 black, trochanters pitchy ; between the middle coxae in male there is a 

 thick tuft of grey hairs. L. 5 mm. 



Male witli the seventh ventral segment of hind body deeply emar- 

 ginate, sixth slightly emarginate with a broad, depressed, punctured 

 space behind, which is bounded on each side by a rather prominent 

 keel, the two keels being prolonged at apex into a blunt tooth and 

 ciliate. 



Marshy and damp places, at roots of grass, in moss, haystack refuse, &c. ; common 

 and generally distributed throughout the kingdom. 



S> providus, v. Eogeri, Kr. Very closely allied to the preceding, 

 but it is more shining, and more coarsely punctured, with the punctures 

 much more rugose and confluent ; the wings are rudimentary ; the head
