Bka(jhynus repressus sp. nov. 

 PI. IV, fig. 6. 



A species allied to B. fumans Fabr., with which it agrees in size, the 

 clothing of the elytra and the character of the strise. It is represented by 

 a single elytron much broader than in B. newherryi and in which the 

 humeral angle is more pronounced; the apical margin is decidedly truncate 

 and the elytron is furnished with tolerably coarse ridges, interrupted so af 

 to give them a bead-like appearance, or a chain of slightly elongated 

 tubercles; the interspaces are flat and scantih' clothed with tolerably long- 

 delicate hairs. 



Length of elytron, 6 mm.; breadth, 3.2 mm. 



Florissant, Colorado; one specimen. No. 8316.

 excepting one from amber. In the Pleistocene, two existing species 

 have been found in Bavaria, besides two extinct forms in Bavaria and 

 Pennsylvania.
