the sides ; marginal stria inferior, distinct from the outer subhumeral at base ; 

 inner subhumeral distinct in apical half to two-thirds ; oblique humeral deep 

 but rather short ; dorsals long, subequal, strong, slightly punctulate, the 

 fourth rather narrowly arched at base, joining the entire sutural. Pygidia 

 not very coarsely' but deeply and closely punctate. Prosteruum slightly con- 

 vex, the striae rather approximate, variable in length, generally more or less 

 convergent anteriorly. Mesosternum broadly sinuate, rather coarsely but not 

 very densely punctate, the apical stria entire. Anterior tibiae expanded 

 externally toward apex as usual, finely multispinulose. Length 3.0-3.4 

 mm. ; width 2.0-2.25 mm. 



Wyoming (Cheyenne). Mr. Soltau. 



A fine distinct species, readily known from any other of this 

 group by its oblong form and coloration. It may be placed near 

 Jioridde, but differs notably in the feebly convex and non-carinate 

 prosternum. 



S. audax. — Rather broadly oval, convex, black, polished, without me- 

 tallic lustre. Head finely, sparsely punctate, the marginal stria obsolete above 

 the eyes and at apex. Prothorax rather more than twice as wide as long ; sides 

 strongly convergent and very feebly arcuate, broadly so anteriorly ; marginal 

 stria deep, entire ; disk finely, sparsely punctulate, rather coarsely and per- 

 forately but not densely punctate in a broad area at the sides and unevenly 

 along the base. Elytra at basal third slightly wider than the prothorax, two- 

 thirds longer, distinctly wider than long ; punctures strong but very sparse, 

 gradually becoming minute to the base throughout the width ; marginal stria 

 inferior, nearly straight, the attendant series of punctures strong and close- 

 set ; outer subhumeral acutely defined below the humeri, one-fifth the total 

 length ; inner represented by a mere short trace behind the middle ; oblique 

 humeral very fine and feeble ; dorsals fine, broadly arcuate, punctured within, 

 the first extending to apical fourth, two to four evenly, gradually shorter, the 

 fourth ending at the middle, one to three hooked at base, the fourth broadly 

 arched to the sutural which is only distinct in median third of the length ; 

 apical stria extending only to the middle of each elytron. Propygidium very 

 short, five times as wide as long, strongly, densely punctate, gradually more 

 finely so from apex to base ; pygidium large, convex, strongly, closely punc- 

 tate, the punctures gradually subobsolete toward apex. Prosternum evenly 

 but distinctly convex, with a median fovea at some distance behind the ante- 

 rior margin, the striae strong, distant, somewhat divergent anteriorly ; sides 

 anteriorly deeply foveate. Anterior tibise finely serrulate. Length 2.9 mm. ; 

 width 2.2 mm. 



New Jersey. 



Greatly resembles paeminosiis, but differs in the obsolete basal 

 parts of the sutural stria, the shorter second and third dorsals, 

 much less arcuate toward base, more approximate prosternal striae 

 and several other characters.
