Coleopterological Notices, V. 573 



very oblique ; dorsals distinct, the first extending almost to the apex, arcuate 

 behind, two to four abbreviated far behind the middle, the latter arched at 

 base, joining the sutural which is entire but faint ; punctures not fine but 

 sparse and very shallow, extending, near the suture, fully to basal fourth. 

 Pygidia rather finely, very densely and somewhat unevenly punctate. Pro- 

 sternal striae as in hcidulus. Anterior tibise with three very large external 

 teeth. Length 1.9 mm. ; width 1.4 mm. 



California (San Diego). 



This species greatly resembles a very small hicididus, but is dis- 

 tinguishable at once by its small size and by the elytral punctured 

 area advancing well toward the base. Both this species and the 

 next differ radically from lucid^dus in having the pronotal hypo- 

 mera feebly indexed, almost horizontal, coarsely, densely punctured 

 and clothed with long coarse pubescence which bristles also along 

 the sides. In lucidulus the hypomera are strongly inflexed, smooth 

 and glabrous. 



S. servilis. — Oval, strongly convex, polished, rufo-piceous in color. Head 

 impunctate, with an arcuate subapical transverse line, strongly margined at 

 the sides and apex ; clypeus feebly sculptured. Prothorax about twice as wide 

 as long, the sides strongly convergent and broadly arcuate from base to apex; 

 marginal stria strong ; disk sparsely, rather finely but strongly punctate to- 

 ward the sides and apex, broadly impunctate behind the middle, moderately 

 punctate along the base ; punctures only feebly rugiform. Elytra near the 

 base slightly wider than the prothorax, barely one-half longer, the punctures 

 fine, sparse, not entering any of the iiiterstriae ; extending near the suture 

 about to basal third ; external stria strong, arcuate toward base ; outer sub- 

 humeral wanting ; inner feeble, oblique, separated from the oblique humeral, 

 which is strong ; dorsals distinct, the first nearly attaining the apex but 

 becoming fragmentary and feeble behind, second to fourth abbreviated at the 

 middle, the latter broadly arched at base, joining the sntural which is entire 

 but fine. Pygidia not coarsely but deeply and rather closely punctate. Pro- 

 sternal strije nearly as in lucidulus. Anterior tibise strongly tridentate, with 

 some long distant hairs externally toward base, and a fringe of very long 

 close-set hairs internally toward apex ; anterior femora with a lower fringe of 

 long broad flattened hairs. Length 2.0 mm. ; width 1.4 mm. 



Texas (Galveston). 



Allied to the preceding, but readily distinguishal)le by its finer 

 and sparser punctuation, longer prothorax with more convergent 

 sides, shorter elytral strise, more evenly oval and less oblong form 

 and many other characters. The three large teeth of the anterior 

 tibiae in this and the preceding species are formed principally by 

 enormous inset spines, shortened and broadly rounded at tip. In
