coxae separated by nearly one-half of their own width. Length 2.4-3.0 mm. ; 

 width 0.75-0.9 mm. 



California (San Francisco). 



This is the commonest species of the middle coast regions, and is 

 not closely allied to any other. It is represented by a large series. 



R. sprettlS n. sp. — Cylindrical, shining, dark rufo-piceous, the occiput, 

 legs and antennal club paler, rufous. Head almost impunctate toward base ; 

 beak finely but strongly, densely punctate, very short, wider than long, 

 scarcely as long as the head, conical, narrowly impressed along the middle ; 

 eyes well developed, moderately prominent ; antennas inserted just before the 

 eyes, the scape not quite as long as the funicle, swollen and setose near the 

 middle beneath as in pallens, funicle moderately slender, the second joint a 

 little wider than long and but slightly longer than the third, club abrupt, 

 oval, nearly as long as the preceding five joints. Prothorax slightly wider than 

 long, the sides very feebly convergent and straight from before the base to the 

 subapical constriction, which is pronounced but not abrupt ; apex scarcely as 

 wide as the base ; disk very finely, closely punctate, without impunctate line. 

 Elytra not distinctly wider than the prothorax and about twice as long, three- 

 fourths longer than wide, parallel and straight at the sides, obtuseJy rounded 

 at apex, the disk with scarcely at all impressed series of large, shallow, 

 rounded and well separated punctures, the intervals nearly flat, not wider than 

 the strial punctures, each with a single series of minute remote punctures. 

 Prosternum finely, densely punctate, the metasternum and abdomen toward 

 base finely but more sparsely so ; fifth segment finely, extremely densely punc- 

 tate and dull. Anterior coxae separated by barely one-fourth of their own 

 width. Length 2.3 mm. ; width 0.8 mm. 



California. 



Related to angularis Lee, but with shorter prothorax and elytra, 

 the serial punctures of the latter being larger, more distant and less 

 deeply impressed, the pronotum is much more finely and closely 

 punctate, and the beak is impressed in the middle. The first ab- 

 dominal suture is deeply impressed and nearly straight. A single 

 specimen. 



It. di.lata.tus n. sp. — Cylindrical, robust, polished, dark rufo-piceous, 

 the legs and antennal club paler. Head sparsely but strongly, the beak more 

 finely but rather densely, punctate, the latter nearly as long as wide, conical, 

 a little longer than the head, feebly impressed or flattened and less densely 

 punctate along the middle ; eyes small, rather feebly convex, situated much 

 nearer the prothorax than the tip of the beak ; antennae inserted just behind 

 the middle, the scape long but not quite as long as the funicle, gradually, 

 strongly clavate, funicle cylindrical, the basal joint rather more robust and 

 as long as the next two, second distinctly wider than long and barely longer 

 than the third, club rather abrupt but not longer than the four preceding
