reticulate, much more strongly so toward base. Head very nearly as wide as 

 the prothorax ; eyes rather small, very prominent ; antennal pi'ominences 

 rather large, moderately conspicuous ; suture fine but distinct ; surface behind 

 the suture dull and densely granulate, finely, rather densely but very indis- 

 tinctly punctate ; vertex neither tuberculate nor foveate, rather convex ; epis- 

 toma shining, coarsely reticulate ; antennae rather robust ; second joint nearly 

 as long as the next two, third but slightly shorter than the fourth and fifth 

 together, four to six short, the latter transverse, seven to ten rather abruptly 

 wider and gradually longer, the tenth nearly two-thii-ds wider than long, 

 eleventh short, much shorter than the two preceding combined. Prothorax dis- 

 tinctly narrower than the base of the elytra, scarcely one-fifth wider than long ; 

 sides in anterior two-thirds parallel and very slightly arcuate, then convergent 

 and feebly sinuate to the basal angles, which are obtuse and very narrowly 

 rounded, not at all prominent, the acute lateral edge entirely disappearing 

 just before attaining them ; lateral angles very obtuse and rounded but some- 

 what distinct, apical distinctly rounded ; apex about one-third wider than the 

 base, both truncate ; disk rather convex, very densely but somewhat indis- 

 tinctly punctate, densely but not distinctly pubescent, the median groove 

 rather fine but deep and distinct. Ehjtra quadrate, scarcely one-fourth wider 

 and two-fifths longer than the prothorax, rather convex, broadly impressed 

 toward base near the suture ; sides parallel ; disk rather coarsely, very densely 

 and deeply punctate, the punctures separated by scarcely more than one-half 

 their own diameters, the intervals polished although feebly rugulose ; pubes- 

 cence moderate in length, rather coarse and dense, flavo-ciiiereous and con- 

 spicuous. Abdomen very slightly narrower than the elytra, finely, sparsely 

 punctate, rather coarsely and densely so beneath. Length 2.8 mm. 



California (Lake Tahoe, G200 feet). 



A small species, quite distinct in its very dense punctuation ; the 

 absence of an acute lateral margin near the basal angles of the pro- 

 thorax will distinguish it from its nearest allies ; it should be placed 

 near sinuatus Lee. 



The hypomera are very broadly, feebly concave and rather more 

 than one-half as wide as the distance thence to coxae, the sutures 

 distinct, the coxal fissures moderate in length and widely open. The 

 mentum is shining, coarsely reticulate and broadly, rather strongly 

 impressed in the middle throughout its length, the coriaceous hypo- 

 glottis very short and not distinct. 



B. gentilis n. sp. — Rather slender and convex, black throughout ; legs 

 rufo-testaceous ; an eunse black, the two basal and eleventh joints paler, piceo- 

 testaceous ; head and pronotum feebly shining, the former finely granulose, 

 transversely reticulate near the base, the latter more coarsely granulato-reticu- 

 late and shining ; elytra and abdomen polished, the latter coarsely reticulate 

 throughout, the lines very fine. Head very slightly narrower than the pro-
