especially toward the base ; abdomen piceous-black, rufo-piceoiis beneath ; 

 metastei'num black ; legs and antennse pale testaceous, the latter infiiscate 

 toward apex ; head and pronotum feebly shining, rather coarsely and strongly 

 grannlato-reticulate ; abdomen finelj', evenly and feebly reticulate throughout, 

 polished. Head slightly narrower than the prothorax ; eyes large ; surface 

 rather depressed, finely, very sparsely and indistinctly punctate, not tubercu- 

 late ; median fovea rounded, distinct ; transverse impressed line distinct ; ' 

 antennal tuberculations small, feeble ; suture fine, feebly defined ; antenn* 

 rather strongly incrassate ; second joint more robust and nearly as long as the 

 next two, five to seven increasing gradually in width, eight to ten wider, two- 

 thirds wider than long, eleventh not as long as the two preceding combined. 

 Prothorax just visibly narrower than the base of the elytra, nearly one-half 

 wider than long ; sides in anterior two-thirds parallel and broadly but dis- 

 tinctly arcuate, then convergent and straight to the basal angles, which are 

 obtuse, slightly rounded, rather distinct but not at all prominent ; lateral 

 angles broadly rounded, not distinct, apical slightly obtuse and very narrowly 

 rounded ; apex truncate, less than one-third wider than the base, which is 

 broad and feebly arcuate ; disk rather finely and sparsely punctate, the punc- 

 tures deep and distinctly defined, sliglitly closer toward base ; pubescence 

 moderate in length, sparse, pale fiavate ; median groove rather fine but very 

 deeply impressed and conspicuous. Elytra nearly as long as wide, one-half 

 longer and nearly one-fourth wider than the prothorax ; sides straight, slightly 

 divergent ; surface distinctly impressed near the suture at base, densely, rather 

 finely punctate, the punctures very deep and distinct and separated by slightly 

 more than their own diameters ; jiubescence fine, moderate in length. Abdomen 

 nearly as wide as the elytra, very finely, sparsely punctate ; under surface 

 finely and rather sparsely so. Length 3.9 mm. 



Iowa. 



The hypomera are moderate in width, deeply concave throughout, 

 the lateral edges being very prominent; sutures distinct; coxal 

 fissures moderate in length, widely open. The mentum is large 

 and extremely feebly concave throughout its extent; it is rather 

 shining and coarsel}'" reticulate, the membranous hypoglottis very 

 short, inflexed and inconspicuous. 



Belongs near laticollis, but is well distinguished by its more 

 shining head and pronotum, the punctures of the latter being better 

 defined and the basal angles rather more distinct, by its relatively 

 larger and more finely punctate elytra, less concave mentum, much 

 wider pronotal hypomera, shorter coxal fissures, and larger but less 

 prominent eyes. 



B. lllOiiticola n. sp. — Rather slender, black ; elytra and antenna pice- 

 ous-black, tlie latter very slightly paler toward base; legs rufous; head and 

 prothorax dull, densely granulose ; elytra and abdomen polished, the latter
