 In XheO the abdominal sixth ventral Joint at tip feebly emarginate. 

 Distributed in the mojority of continentsi it is here very common 

 on all kinds of ground, under the plant-cover anu at rotting plants, 

 often numerous in alluvium. 



50. Ph. trossulus Nordm. 



(Nordm. Symb. 1C2; Kraatz Ins. D. II, 616; Thorns. Skand. Col. II, 

 171; Muls. et Rey Brevip. 1877, 413; ianglb. Kaf. I.i. II, 460). 



Most often larger and more robust than ni^ritulus . to which it in 

 other respects is very closely allied, and of v.hich it sometimes is 

 considered a variety (Fauvel). It is separated by the following, often- 

 est distinct deviationsi 



The head is broader, in the jg as broad as pronotum, in the O broad- 

 er than pronotum, rounded off square; pronotum proportionately broader, 

 either of even breadth or posteriorly feebly narrowing; elytra shorter, 

 at most as long as pronotum, most often a little shorter than same. 

 L. 4.5-E.5 mm. 



Distributed especially in North Europe; in this country however 

 it is rare or local, on damp ground and in alluvium. (North Sjaelland 

 in several places, Sorjs^, Fakse; Xykobing, F. ; Odense). 



A closely allied, a little larger species, Ph. astutus Er., sepa- 

 rates from the two preceding species mainly by this, that the middle 

 punctures in the transversal row of the forehead are set obliquely be- 

 fore the outer ones, that the third antennal Joint is longer than in 

 nigritulus and trossulus , almost 1^ times as long as the second, and 

 that the first Joint of hind tarsi is as long as the claw-Joint. I. 

 6-6.5 mm. (Kraatz, ianhlb,).
