two but very much longer than the third, slightly thickened. Prothorax rela- 

 tively moderate in size, as long as wide, rather strongly inflated and rounded 

 anteriorly, with only feeble trace of angulation before the middle; sides 

 strongly oblique posteriorly and broadly, feebly sinuate toward base, the 

 angles slightly more than right; base narrow, much less than }-2 the maximum 

 width and narrower than the head; disk feebly, longitudinally convex an- 

 teriorly, the impressions all very feeble; side margins moderately reflexed. 

 Elytra almost evenly but rather broadly elliptical, quite full at the humeri, 

 ^5 longer than wide, 3 times as long as the prothorax and 275 times as wide, 

 strongly convex, the margin narrow; strise coarse and deeply impressed, with 

 rather coarse, uneven and widely separated punctures, the intervals convex, 

 much interrupted even toward the suture and greatly broken up broadly 

 toward the sides, but with the strise distinctly traceable throughout as usual 

 in this group. Length 14.0-16.5 mm. ; width 6.5-8.3 mm. 



California (exact locality not recorded). 



In the male, which is the sex described above, the pubescent 

 pad of the first anterior tarsal joint is very small and dense, 

 broadly rounded and occupies fully apical third. The female is 

 larger in the body and with the elytra relatively distinctly more 

 inflated but with the prothorax not at all smaller, even relatively. 

 This species is closely related to convergens, but differs in its 

 relatively larger prothorax, with the oblique sides more broadly 

 and distinctly sinuate toward base, in the larger size of the body, 

 less sexual difference in the form of the hind body and several 

 other features. Three specimens. 



25. B. porcatus n. sp. — Eather narrow and elongate, moderately ventrl- 

 cose, alutaceous, without trace of bluish lustre, the elytra rather shining ; body 

 deep black throughout. Head somewhat stout and only moderately elongate, 

 distinctly rugose, the gense feebly developed, deeply incised ; supra-orbital 

 ridges strong but shorter than usual ; antennae scarcely ^ as long as the body, 

 just visibly thicker toward base, the first joint distinctly thicker, obconic and 

 only slightly shorter than the next two, the seta very nearly at the apex. 

 Prothorax relatively well developed, dilated and rounded anteriorly, feebly 

 subangulate before the middle, the sides becoming deeply sinuate posteriorly, 

 parallel and straight in basal fifth or sixth, the angles right and bluntly 

 rounded ; base fully % the maximum width and about as wide as the head ; 

 disk feebly convex, the impressions slight ; reflexed margins moderate. Elytra 

 almost evenly elongate-elliptical, not very full at the humeri, the latter ob- 

 liquely rounded, 2% times as long as the prothorax and barely 2}4: times as 

 wide, % longer than wide, the reflexed margins fine ; disk strongly convex 

 and rugose, the strise coarse and deeply impressed, the punctures rather large 

 but widely separated and not very distinct ; intervals convex, irregular and 

 much interrupted throughout, gradually more frequently toward the sides but 

 with the strise readily traceable throughout the width. Length 15.0 mm. ; 

 width 6. 4 mm.
