112 AMERICAN COLEOPTERA. 



small, and each differs in several details. Languidus Csy., 

 is still nearer, but the head is said to be not foveate, the 

 elytra are piceous and the prosternal sutures feeble and 

 indistinct. 



B. apicalis n. sp. 



Black, elytra piceous with the sides posteriorly and the apex gradu- 

 ally changing to yellowish-brown, legs and antennae rufous. Head 

 and prothorax densely finely granulato-reticulate and dull ; elytra not 

 reticulate, moderately shining, abdomen very finely feebly reticulate 

 and quite strongly shining. Antenna; moderately incrassate, joints 

 2-3-4 gradually shorter, the second slightly thicker than the third and 

 about one-third longer, fifth barely as wide as long, sixth a little trans- 

 verse, tenth one-third wider than long, eleventh not quite as long 

 as the two preceding. Head distinctly but not deeply or closely 

 punctate posteriorly, vertex not evidently tuberculate, occipital fovea 

 small ; frontal suture fine, slightly impressed, epistomal margin finely 

 tuberculate each side ; eyes strongly prominent. Prothorax a little 

 wider than the head, rather strongly transverse, sides parallel and 

 distinctly arcuate in apical three-fifths, then covergent and rather 

 strongly sinuate to base, the base angles a little obtuse, with narrowly 

 rounded vertices, apical angles quite sharply defined ; dorsal line fine, 

 feebly impressed, subobsolete for a short distance at its extremities ; 

 punctuation fine, moderately close. Elytra about as long as wide, at 

 base evidently wider than the prothorox, sides diverging a little to 

 apex, rather densely finely punctate. Abdomen finely sparsely punc- 

 tate above, beneath more closely and less finely so. Hypomera nar- 

 row, feebly impressed along the outer margin, a little narrowed at the 

 coxal fissures, where the width is only about one-third the distance to 

 the coxa? ; fissures long and widely open. Mentum large, broadly 

 feebly impressed longitudinally, the impression not deeper posteriorly. 

 Length 5 mm. 



California (Raymond). Four examples collected by Dr. 

 Fenyes. 



Allied to ruficornis, but larger and broader, the anterior 

 thoracic angles more prominent and the antennas less dark 

 externally, the mentum nearly flat. In ruficornis the seventh 

 ventral is produced at middle as usual in a more or less 

 pointed cuspiform lobe ; in apicalis the lobe is rather widely 

 truncato-emarginate. 

 B. fratellus n. sp. 



Very similar to ruficornis, differing as follows : 



The size is uniformly smaller, the length varying from 3
