 basal segment, fifth segment with a small strong rounded impression.

California (San Bernardino), 



This species resembles gregalis but differs in its more convex 

 form, duller lustre, much more approximately punctate elytral 

 striffi, notably denser abdominal punctuation, stronger basal im- 

 pression of the abdomen iii the male and, especially, in the structure 

 of the anterior tarsi of that sex. In gregalis the third joint is dis- 

 tinctly shorter than the second, while in sequalis the second joint is 

 not only longer than in gregalis, but is not couspicuousl}^ longer 

 than the third. 



In sequalis, contrary to the general rule, the pronotal punctures 

 become rather finer laterally. 



The type is unique. There are two specimens before me from 

 Utah which indicate a closeh^ allied but distinct species. 



26 B. f Ulieliris n. sp. — Oblong-oval, moderately convex, black ; legs 

 dark rufo-piceous ; integuments rather strongly shining ; pubescence short, 

 coarse, very sparse, easily removable, pale fulvous in color and distinct. 

 Head transverse, feebly convex, rather finely and densely punctate ; upper 

 lobe of eyes small ; antennse not very robust, the three outer joints somewhat 

 abruptly but not greatly dilated, third joint much shorter than the next two, 

 eleventh much narrower than the tenth. Prothorax about one-half wider than 

 long, feebly narrowed from base to apex ; sides feebly arcuate, straight or very 

 feebly, broadly sinuate toward base, the latter transverse, with moderate sinua- 

 tions ; basal angles right, not at all rounded; apex feebly emarginate in 

 circular arc ; disk evenly convex, rather finely, moderately densely punctate 

 toward the middle wliere the punctures.are generally separated by distinctly 

 more than their own diameters, distinctly larger and very dense hear the sides 

 but with slight tendency to longitudinal coalescence. Scutellum rather large, 

 transversely ogival, finely, rather densely j>unctate. Elytra scarcely wider 

 than the prothorax and nearly three times as long, rather broadly, paraboli- 

 cally rounded behind ; sides feebly arcuate, rather more distinctly so behind ; 

 disk with very fine stria> which are extremely feebly impressed and very finely, 

 rather approximately punctured, rather moi'e strongly impressed and very 

 slightly more coarsely punctate externally; intervals flat toward the suture, 

 more convex laterally, finely, sparsely punctate. Abdomen shining, finely, 

 sparsely punctured and with coarse, sparse, pale flavo-cinereous pubescence, 

 moderate in length and quite conspicuous. Leys rather long.
