distant from the lateral ; oblique humeral fine ; inner subhumeral isolated, 

 short, strongly oblique, at about the middle ; dorsals rather fine, acute ex- 

 ternally, finely punctate within, one to three gradually longer, the first 

 extending about to the middle, the third to apical third, fourth shorter, 

 extending slightly behind the middle, broadly arched at base, joining the 

 entire but fine sutural ; disk strongly, distinctly punctate throughout, the 

 punctures small and sparse near the scutellum, gradually coarse dense and 

 aciculate behind. Pyyidia not coarsely but deeply, extremely densely punc- 

 tate. Prosternum acutely compresso-carinate, the strife fine, ascending, abbre- 

 viated behind the fovese which are very small. Anterior tibiie mullispinulose 

 externally, the spinules erect and short. Length 3.5 mm.; width 2.6 mm. 



California (San Diego). 



This fine species is allied to vestitus, but is larger and blacker, 

 with the punctuation coarser and denser, and the integuments still 

 more opaque throughout. The prosternal striae are shorter and 

 abbreviated far behind the foveas, and the surface is more acute 

 and compressed than in veatitus; in the latter, also, the apical 

 stria of the elytra is abbreviated at outer third or fourth, and the 

 punctures of the elytra become abruptly fine and excessively dense 

 broadly along the apex. 



S. impunctellllS. — Broadly oblong-oval, strongly convex, polished, 

 black, without aeneous lustre. Head impunctate, anuately and unevenly 

 eroded anteriorly, surrounded at the sides and apex by a deep groove and 

 beaded edge, rectangular at the sides. Prothorax twice as wide as long, the 

 sides rather strongly convergent and nearly straight to apical third, then 

 gradually broadly rounded to the obtuse apical angles ; marginal groove deep, 

 distinct throughout the apex ; disk feebly and not densely punctato-rugulose, 

 smooth in the middle except toward apex, coarsely closely and deeply punc- 

 tate along the base. Elytra distinctly wider and three-fourths longer than 

 the prothorax, completely devoid of all trace of punctuation at any part ; 

 marginal stria deep, not coarse, abruptly abbreviated at outer third of the apex ; 

 outer subhumeral fine, distant from the marginal ; striae throughout as in 

 sphieroides, except that the fourth is distinctly shorter than the third, the 

 sutural broadly interrupted near the apex. Propygidium transversely bi- 

 impressed and subimpunctate in basal half, the punctures apically very fine, 

 dense; pygidium very finely, evenly, not densely punctate. Prosternum with 

 the two almost entire approximate striae rapidly divergent behind ; lateral 

 convergent carinse strong, the subapical foveas deep, rounded ; mesosternum 

 finely, sparsely punctate, the apical stria deep, entire ; transverse suture 

 punctate ; metasternum with a clearly limited, transverse, strongly and con- 

 fusedly punctured band posteriorly. Length 4.2 mm. ; width 3.0 mm.

In general form and structure this species is a close ally of sphae- 

 roides, but it differs greatly, not only in its larger size and wholly
