 grooved, but often smooth. Elytra rather uneven, these and pronotum 

 somewhat less densely punctated than in ^eniculatus , whereas abdomen 

 is rather robustly and equally densely punctated as in same. - From 

 the likewise closely allied impressus it is easily separated by; less 

 distinctive bronze-reflection, not grooved pronotum, and especially by 

 the more dense and robust punctation of abdomen. L. 4 mm.

 It was first found in a woodland pool at Ringspen in Skaane (Thorns.) 

 later in several places in Sweden, Norway and in middle European high- 

 land forests. In Lenmark its occurrance has heretofore not been fully 

 verified, but some specimens from alluvium at Lyngby lake (4. 1910 author) 

 are rather certainly of this species.

Among our closely allied species easily identified by the decided 

 metallic lustre of the body. 



Black, glistening with distinctive bronze- or ore-reflection, very 

 finely, sparsely whitish haired; maxillary palpi, antennae and legs 

 light reddish-yellow; antennal first joint and club, most often also 

 the middle and hind knees, feebly or only suggestively brownish. 



The head is fully as broad as the elytral base, considerably broad- 

 er than pronotum, with dense and rather robust punctation; forehead 

 between the eyes with two broad, rather deep grooves, separated by a
