Hudson's Bay Territory; Mr. Ulke. A singular little species, 

 which I was at first inclined to class with B. salebratum, quadru- 

 lum, &c, but the two dorsal punctures are placed upon the third 

 interval, and are not connected with the third stria. I have there- 

 fore, for want of a better place, included it in Notaphus, with 

 several other species in which the outer strite of the elytra are 

 somewhat obliterated towards the tip.

Louisiana ; Dr. Schaum. Smaller than the preceding, and 

 ecpially robust, but with the thorax more transverse and less con- 

 vex, and very faintly sinuated on the sides just by the base, so that 

 the hind angles become slightly prominent.
