9. B. earinatiiin Lee. — Form moderately robust, slightly convex; colar 

 coppery bronze, shining. Head slightly narrower than the thorax at ajiex, in- 

 serted therein nearly to the eyes, finely alutaceous ; palpi rufo-ferrugiuous. darker 

 at tip; anteunfe scarcely one-lialf as long as the body, piceous, the first three 

 joints and sometimes the fourth at base rufous. Prothorax rather more than one- 

 half wider than long, very distinctly wider at base than apex, not alutaceous, 

 feebly transversely wrinkled along the median line, slightly rugose at base: apex 

 nearly truncate ; median line fine, extending between the transverse impressions, 

 which are moderately distinct ; basal impressions broad, deep, bistriate, the outer 

 stria small and close to the angle; sides with the margin very narrowly refiexed, 

 Teebly arcuate in front, not sinuate behind ; hind angles not prominent, sub- 

 obtuse but not rounded, finely cariuate. Elytra slightly wider than the thorax, 

 widest about one-fourth from base, oblong-ovate, deeply striate ; strige entire, 

 deeply, almost creuulately punctate, the punctures less evident towards the tip; 

 intervals convex, the third with the first dorsal puncture about or slightly behind 

 the middle, the second about one-fifth from apex. Beneath dark aeneous, shining. 

 Legs Eeneo-ferruginous, the femora darker. Length .24-. 26 inch ; 6-6.5 mm. 



Closely allied to scalpturatum. The thorax is, however, wider in 

 proportion to its length, not alutaceous, with the sides not sinuate 

 behind and the hind angles subobtuse. The elytra are only slightly 

 wider than the thorax and are widest about one-fourth from base ; 

 the strise are slightly less deep and the intervals somewhat less con- 

 vex. The form is less elongate, the surface more shining, and the 

 color usually more bronzed. From the other species of the group it 

 may readily be distinguished by the characters previously mentioned. 



The specimens. in the LeConte collection are labeled " California," 

 but are probably from the Valley of the Colorado River, as the spe- 

 cies was described from that region. The only other specimens that 

 I have seen are from Arizona. For the single example in my cabinet 

 I am indebted to Dr. Horn. 



10. B. seiilptiirattiin Mots.— Form moderately elongate, convex: color 

 varying from bronze to black, more or less shining. Head scarcely narrower 

 than the thorax at apex, alutaceous; palpi piceous; anteunte rather less than 

 cue-half the length of the body, the first joint rufous, as are also sometimes the 

 second and third at base. Prothorax nearly one-half wider than long, wider at 

 base than apex, slightly rugose at base, transversely wrinkled along the median 

 line; apex nearly truncate; median line fine, abbreviated in front; transverse 

 impressions feeble, the anterior sometimes nearly obsolete; basal impressions 

 broad, moderately deep, bistriate, the outer stria small and close to the angle ; 

 sides with the margin very narrowly reflexed, moderately arcuate, sinuate in 

 front of the hind angles, which are subacute, finely carinate. Elytra about one- 

 third wider than the thorax, oblong-ovate, subparallel. very deeply striate; strite 

 very deeply, almost crenulately punctate, the punctures scarcely less obvious at 



•apex; intervals very convex, the third with the first dorsal puncture about the 

 middle, the second about one-fourth from apex. Beneath dark seneous, shining. 

 Legs feueo-piceous. the tiliiai usually paler. Length .24 .27 inch ; 6-6.75 mm.
