trapezoidal, more than ^ and ^ wider than the eighth, and ^ and 

 |- wider than long respectively ; eleventh fully as thick as the 

 tenth and as long as the two preceding, obliquely pointed toward 

 apex. Prothorax not quite as long as wide, nearly ^ wider than 

 the head, dilated and broadly rounded laterally in apical half, the 

 sides thence strongly convergent and feebly sinuate to the base ; 

 four subbasal fovese very irregular and feebly connected in twos, 

 the sides more anteriorly also having two or three deep approxi- 

 mate fovese. Scutellum very narrow and elongate, narrowly 

 parabolic. Elytra scarcely more than f longer than wide, 

 slightly less than three times as long as the prothorax and 

 nearly ^ wider, oval, widest at basal ^ but with the sides broadly 

 arcuate, narrowly parabolic toward tip ; subhumeral impression 

 quite distinct and elongate ; inner fovea large ; suture not modi- 

 fied, the impressions obsolete. Legs slender, the anterior femora 

 rather strongly, the four posterior ver}'" feebly, clavate ; tarsi 

 long, the posterior very slender, with the four basal joints de- 

 creasing gradually and not very rapidly in length. Length 1.15 

 mm. ; width 0.5 mm, 



California. This species is one of the smallest of Sc3'dm8enus 

 proper and may be known by its coloration, sparse and rather 

 small eh'tral punctures and other characters. 



The name oautus was applied in manuscript by LeConte to the 

 entirely testaceous specimens of this species, and the name is 

 published, as far I am aware, only in the LeConte list of Coleo- 

 ptera. 



10. S. pacificus n. sp. — Elongate, suboval, moderately ventricose, pale 

 and uniform rufo-testaceous throughout, polished, subimpunctate, the elytra 

 sparsely and very feebly though rather coarsely punctulate, rather sparsely and 

 inconspicuously pubescent, the hairs of the elytra moderate in length, suberect 

 and recurved. Head wider than long, the eyes large, prominent and subbasal, 

 the tempora very short and convergent ; impression of the vertex deep and 

 distinctly double at the bottom, subquadrate. Antemiie fully ^ as long as the 

 body, very evenly, gradually and moderately incrassate from near the base to 

 the apex ; second joint much shorter and narrower than the first, }4 longer 

 and only slightly thicker than the third, cylindric and 3^ longer than wide ; 

 third to tenth increasing in width and gradually more transverse ; fifth longer 

 than wide, spherical at base and apex ; sixth as long as wide ; seventh 

 distinctly wider ; seven to ten transverse, the club, if any, being 5-jointed. 

 Prothorax almost as long as wide, more than 34 wider than the head, dilated 

 and strongly, circularly rounded at the sides in apical half, constricted at basal 

 third ; surface with a short transverse impression near the base at the middle,
