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 striae of the elytra are 

 somewhat obliterated towards the tip.

Louisiana ; Dr. Schaura. This species is as large as T. proxi-

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

 equally 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.
