 from the Pyrenees, Middle iingland, Scotland, and Finland, and every- 

 where particularly rare. It occurs, like the other species of the 

 genus , quite surely under leaves and moss on damp ground, but also 

 in fungi. In Denmark it has recently been found in Dyrehaven near 

 Copenhagen (3. 10. 1S09 Fru ^est, 1 specimen in fungus). 



A very closely allied species is B. rugipennis Pand. (cf. Fowler, 

 Col. Br. Isl. II, 209). It is of same form and size, but is somewhat 

 of darker color, antennae less sturdy, and the intervals between the 

 punctate stripes of elytra are more or less distinctly ruguloae- 

 punctate. The dorsum stripe has 6-8 punctures. - It is distributed 

 to about same extent as crassicornis . and is also found in Norway 

 (CI. Srill).

This differs from the three preceding genera mainly by this, that 

 the last joint of maxillary palpi is very small, styliforra, much 

 finer and shorter than the next-last (Fig. 109). 



The body is more or less narrowly fusiform, occasionally almost 

 of uniform breadth. In the majority of species the antennae do not 

 reach over or beyond the posterior margin of pronotum, but in a few 

 they are considerably longer (subgenus Isohnosoma ). Head and prono- 

 tum naked, shiny and smooth, this one however has, besides single 

 bristle-bearing punctures along the margins, occasionally also dis-
