half ; disk very finely, feebly and sparsely punctate, except very abruptly in 

 lateral fourth, where the punctures become extremely coarse and deep, elon- 

 gate-oval and not very coalescent. Elytra equal in width to the prothorax 

 and about three times as long ; sides parallel and nearly straight ; apex 

 obtusely ogival ; disk punctured nearly as in convexicolle but more coarsely, 

 less densely and less asperately so laterally, and still more finely and sparsely 

 so toward the suture. Abdomen finely, sparsely punctate, the metasternum 

 from coxa to transverse groove distinctly shorter than the first ventral segment. 

 Legs slender. Length 6.5-7.5 mm. ; width 2.7-3.4 mm. 



California (Kern Co.). 



This species is represented by a large series and cannot fail to be 

 easily recognized by the very peculiar punctuation of the pronotum, 

 subcylindrical form and more than usually elongate prothorax. 

 The punctures toward the sides of the pronotum are very abruptly 

 five or six times as large as those of the broad median portion, the 

 latter being very sparse as well as fine. 



£ll. politlim n. sp. — Elongate-oval, strongly convex, castaneous, highly 

 polished, feebly alutaceous toward the apex of the elytra. Head moderately 

 transverse, shining, entire and broadly truncate at apex, rather finely and 

 densely punctate, the punctures distinctly separated ; eyes moderate, the 

 superior fold distinct, strongly arcuate in front of the eye ; antennae slender, 

 third joint fully three times as long as wide, much longer than the fourth, 

 second elongate. Prothorax fully three-fourths wider than long, the apex 

 distinctly narrower than the base, just visibly emarginate, the angles slightly 

 obtuse but not in the least rounded ; base transverse, with the usual feeble 

 median sinuations ; basal angles obtuse, the apex rather acute, not in the 

 least rounded and just perceptibly prominent ; sides evenly and, strongly 

 arcuate throughout ; disk much wider in the middle than at base, convex, 

 rather finely and sparsely punctate, the punctures gradually becoming coarser, 

 about twice as large and dense but not coalescent toward the sides. Elytra 

 slightly wider than the prothorax and a little more than three times as long, 

 gradually rather acutely rounded behind ; sides parallel and feebly arcuate ; 

 width across the humeri, which are narrowly rounded and not jjrominent, 

 quite distinctly greater than the base of the prothorax ; disk convex, finely, 

 rather irregularly and sparsely punctured toward the suture, the punctures 

 very coarse and forming approximate series laterally where they are not per- 

 ceptibly asperate, except feebly so toward apex. Ahdomen rather finely but 

 strongly, sparsely punctate, the metasternum between coxa and groove equal 

 in length to the first ventral segment. Legs slender, the femora rather robust, 

 polished, very minutely and extremely sparsely punctate ; posterior tarsi long 

 and slender, slightly sliorter than the tibije. Length (j.5 mm. ; width 2.8 mm.
