59. B. rocticolle. Depressum, nigro-aeneum nitidnm, thorace quad- 

 rato latitudiue vix breviore, lateribus antice rotundatis postice fere 

 parallelis, angulis posticis rectis subtiliter carinatis, linea dorsali tenui,

New Mexico; Mr. Ulke. This species is allied to B. salebratum 

 and quadrulum ; from the first it differs by the square thorax, and 

 from the second by the more deeply impressed and more densely 

 punctured elytral striae. 



60. B. nebraskense. Depressum, nigrum pernitidum, thorace lati- 



tudine plus sesqui breviore postice angustato, lateribus antice magi 3 

 rotundatis postice obliquis, angulis posticis obtusis baud rotundatis 

 carinatis, linea dorsali tenui, impressionibus transversis profundis, ad 

 basin punctato et utrinque profunde foveato; elytris striis tenuibus 

 punctulatis, externis fere obliteratis, tertia bipunctata, basi late emi

Nebraska, near the Rocky Mountains; a specimen kindly given 

 me by Mr. Hike. This species belongs to the same section with 

 B. complanulum, incertum, &c, from Russian America, but differs 

 from all others in my collection by the elytral striie being finely 

 punctulate, and by the thorax being more narrowed behind, with 

 the basal angles distinctly obtuse. In appearance it bears a strong 

 resemblance to a Blechrus.

 subconvexo latitudiue breviore, postice vix angustiore, lateribus Late 

 rotundatis, angulis posticis obtusis vix brevissime carinatis, linea dor- 

 Bali tenui, impressione transversa antica mediocri, postica profund 

 basin utrinque breviter bistriato et parce punctato, elytris oblongo-oval- 

 ilius, subdepressis, tenuiter striato-punctatis, interstitio 3io bipunot 

 subtus, antennis pedibusque aeneo-nigris. Long. '20. 



Nebraska, near the Rocky Mountains; Mr. Ulke. A very dis- 

 tinct species, belonging to the section Notaphus; the striae are all 

 entire, though the outer ones are less impressed towards the tip. 



6"2. B. morulum. Convexum, aeneo-nigrum nitidnm, thoraoe lati- 

 tudine sesqui breviore postice angustato, lateribus rotundatis, angulis
