At water edges or digging in moist sand brinks; often in company with 



species of Bledius ; distributed same as arenerlus , at most places in this 



country rather rare. 



3. P. alutaceus Thorns. 



(Ihoras. Skand. Col. Ill, 123; I/.ul s. et Rey Bre'vip. 1879, 26; (Janglb. 

 Kaf. M. II, 631). 



From cornutus , of which it apparently is an aberration, and with which 

 it in discription often is united (Erichs. , Kraatz et. al.), it is separat- 

 ed only in thet the elytra are entirely black, completely dull, finer and 

 more sparsely punctated, and the surface more distinctly and densely reti- 

 culated. L. 3-4 mm. 



Together with the preceding, but much rarer that this. 



4. P. nodifrons Sahib. 



(Sahib. Ins. Fenn. I, 412; Erichs. Jen. Spec. Staph. 733 (ex parte); 

 Kraatz Ins. D. II, 844; Thorns. Skand. Gol. Ill, 124; Muls. et Key Bre'vip. 

 1879, 27; Janglb. Kaf. U. II, 632). 



Smaller than the preceding species, identified mainly by the puncta- 

 tion of the thorax. 



(Page 553) 



Black, glistening; elytra black, brown or reddish-brown; legs reddish- 

 yellow, femora often brown. 



The thorax* with robust and rather dense, at middle of head and pro- 

 notum'however more isolated punctation, clypeus smooth; the head either 

 a little broader (d 1 ) or narrower than pronotura (p), posteriorly not con- 

 stricted, the vertex most often not transversely grooved, but at middle 

 with a fine, often very short, almost punctiformis longitudinal groove,
