130 ADEPHAGA. \_Patrolms. 



district, but is not common, and is contined to the Lowlands ; Ireland, near Belfast 

 and Dublin : specimens from mountains and moors are darker as a rule, and smaller 

 thau those found in woods, &c., and are probably intermediate forms between this 

 and the succeeding species. 



P. assixnilis, Chaud. (clavipes, Thorns.). Apterous, pitchy black ; 

 very like the preceding, of which it is in all probability merely a high- 

 land variety ; it is, however, smaller, with more convex thorax, and with 

 the forehead strigose between the frontal furrows ; the thorax also is 

 somewhat narrower at the base ; the strife of the elytra are almost or 

 nearly evanescent at apex, and the third interstice is much wider than the 

 second, and the sculpture of the disc is a little stronger : as, however, 

 intermediate varieties occur, it is sometimes hard to separate these 

 species, and it would perhaps be the best course to class them together 

 as, at all events, races of one species. L. 7-7|- mm. 



Rather widely distributed, but always on moors or in hilly and mountainous dis- 

 tricts ; Cannock Chase ; Matlock and Hathersege Moor, Derbyshire ; Snowdou and 

 other Welsh mountains; Northnmberland and Durham district, Wallington (Power); 

 Mr. Bold says (Cat. p. 7) that his own local examples recorded as here cited proved 

 to be small dark examples of excavatus. Scotland, common in the Highland districts 

 throughout the country, but not found iu the Lowlands ; this latter fact, compared 

 with the Scotch record for P. excavatus above given, goes a long way to prove that 

 this species is nothing but a highland race of the preceding. 



P. septentrionis, Dej. Winged, larger and longer than the two 

 preceding ; pitchy l^lack or with the head and thorax pitchy and the 

 elytra reddish testaceous ; antennae, pitchy red ; thorax broader than 

 long, with the posterior angles sharp, prominent, dorsal furrow and 

 fovese much as in the other species ; elytra longer and with the shoulders 

 considerably more strongly marked, striae almost obsolete toAvards apex 

 and sides, punctuation of striae feeble, almost obsolete ; legs ferruginous ; 

 underside not so thickly or deeply punctured, sides of metathorax 

 (which are plainly punctured in the others) almost smooth. L. 9 mm. 



This is rather a variable species, as may be seen from the list of named varieties 

 appended to it in the European catalogue : it is entii'cly a northern species ; there is 

 cne record from near Waketield, Yorkshii-e, but this is probably an error; it is 

 gumewhat widely distributed but not common iu the Highland districts of Scotland 

 (Tay, Dee, Moray, Solway, Clyde). 



POGONUS, Dejean. 



This genus comprises about thirty species, of which about half belong 

 to Europe ; the remainder occur chiefly in Northern Asia and North 

 America, a very small proportion only being found in the southern 

 hemisphere ; they inhabit damp localities, and are never found except 

 where there is salt ; they occur, therefore, in salt marshes near the coast, 

 on the shores of salt lakes, or at the mouths of tidal rivers, under 

 stones, refuse, &c., and especially in cracks in expanses of mud, from 

 which they emerge in bright sunshine. 



I. Thora.x metallic green, elytra yellow testaceous ; an- 

 tennas red P. LUEiDiPENNis, Qerm.
