few distant fine punctures on the disc, at sides very sparsely punctulate. 

 Elytra sparsely punctured at apex, punctures at middle extending two- 

 thirds to base. External subhumeral very short, humeral oblique, finely 

 impressed, not joining the internal subhumeral which is short aud deeply 

 impressed, dorsals 1-2-3 equal, extending slightly beyond the middle, 

 fourth shorter, arching at base, sutural deeply impressed, basal third ob- 

 literated, joining at apex the marginal line. Propygidium and pygidium 

 sparsely and rather finely punctured. Prosternal striae divergent and 

 nearly horizontal. Legs brownish-red, anterior tibiae finely denticulate, 

 middle and hind tibiae finely biseriately spinulose. Length .0G-.08 inch ; 

 1.5-2 mm. 



One of the smallest species of Saprinus and readily known by the 

 characters in the table. From scrupularis it moreover differs by the 

 entirely smooth disc of thorax, which in that species is moderately coarsely 

 but sparsely punctured. 



Occurs in California. 



S- scrupularis, Lee. Proc. Acad., 1859, p. 315. 



Piceous, shining. Legs brownish-red. Head sparsely punctured, frontal 

 stria slightly visible at the sides. Thorax very sparsely punctulate at the 

 disc, more coarsely and densely at the sides. Elytra at apex sparsely punc- 

 tured, punctures fine at apex and extending in the interstriae and sutural 

 space nearly to base ; external subhumeral short but distinct, humeral 

 finely impressed, internal subhumeral finely impressed, disconnected ; 

 first dorsal extending to middle, second and third somewhat longer, 

 fourth slightly shorter than first, arched at base; sutural finely impressed, 

 basal third obliterated, attaining the apical margin, apical line obsolete. 

 Propygidium and pygidium sparsely and rather finely punctured. Ante- 

 rior tibiae finely denticulate, middle and hind tibia?, finely biseriately 

 spinulose. Length .06 inch ; 1.5 mm. 



Resembles laridus, which, however, has the sutural abbreviated at 

 apex, and the thorax nearly as closely punctured at middle as at the 

 sides. 



Occurs in the Southern States. 



S. wacoensis, n. sp. 



Broadly oval, black shining. Front sparsely, clypeus more densely 

 punctured ; supra-orbital stria obsolete, frontal visible at the sides. 

 Thorax smooth at the middle, moderate densely punctured towards the 

 sides, margin smoother. Elytra sparsely punctured at apex; punctures 

 forming a triangular space, the apex at the basal fourth of the suture ; 

 external subhumeral wanting, humeral fine, oblique, internal subhumeral 

 obsolete ; first dorsal extending four-fifths to apex, second and third 

 nearly equal, slightly shorter than first, fourth extending to middle only, 

 arched at base ; sutural short, feebly impressed, apical fifth and basal 

 third entirely obliterated. Propygidium and pygidium coarsely but not 

 densely punctured. Prosternal striae divergent, feebly ascending, pres- 

 ternum broadly convex. Legs brownish red, anterior tibia? finely semi-
