S. ol>tusilS Lee. — Proc. Ac. Phil., 18.56, p. 17. — Almost evenly elliptical, 

 moderately convex, blackish-piceous throughout the body, legs and antennae ; 

 tarsi slightly paler ; upper surface shining. Head very feebly and sparsely 

 punctate ; antennae nearly as in nitidus, but with the ninth joint rather longer. 

 Prothorax extremely minutely, feebly and sparsely punctate, extremely oljso- 

 letely reticulate in broken wavy lines ; basal lobe very broad and feeble, the 

 bead very fine but somewhat distinct. Scutellum one-half wider than long. 

 Elytra rather obtusely rounded behind, finely but rather distinctly reticulate 

 in transverse wavy lines over the entire disk ; discal stria very strong, coinci- 

 dent with the suture at the apex, becoming obsolete at basal third or fourth ; 

 punctures of the series very fine and feeble but visible, not more distinct but 

 rather wider at the sides, where, however, they do not become crescentiform, 

 but simply a slight deepening of the lines forming the reticulation at the 

 points of attachment of the hairs. Abdomen reticulate, sparsely, coarsely 

 pubescent. Legs moderate ; spurs of posterior tibise very small, subeqiial, and 

 about as long as the exterior spinules of the terminal fimbria ; the correspond- 

 ing tarsi rather slender, nearly three-fourths as long as the tibiae, with the 

 basal joint one-half as long as the second. Length 1.5 mm. 



California (Santa Cruz Co.). 



The metasternal process in this species is rather broad, reticulate 

 but not distinctly punctate, the mesosternum transversely, moder- 

 ately prominent in front of it, the prosternal process strongly 

 dilated and broadly rounded at apex, the spinules rather close and 

 very stout, distinctly shorter than in apicahs, but rather longer 

 than in atteniiatus, in this respect approaching the second of the 

 arbitrary groups into which I have divided the genus. 



The type of LeConte seems to be an unusually robust specimen, 

 and I have several which are distinctly narrower. The under sur- 

 face and antennae are sometimes paler from immaturity. 



S. nanulus n. sp. — Narrowly and evenly elliptical, strongly convex, 

 highly polished, piceous-black thi-oughout above ; legs, antennae and under 

 surface testaceous. Head without trace of punctuation or reticulation ; 

 antennae rather short, the funicle very slender, the outer joints more robust, 

 club rather large and compact, the ninth joint but very slightly longer than 

 the tenth, the eleventh almost as long as the two preceding together, although 

 moderate in length. Prothorax impunctate and not at all reticulate, the median 

 basal lobe broadly arcuate and rather well developed, the marginal bead obso- 

 lete. Scutellum small, ogival, about two-thirds wider than long. Elijtra highly 

 polished, without trace of reticulation except near the apex and narrowly along 

 the sides, where it is very feeble and not at all distinct ; discal stria strongly 

 impressed, totally impunctate, obsolete at basal third ; punctures of the discal 

 series completely obsolete and only represented by the minute hairs, except 

 abruptly, very near the sides, where tliey become dilated, distinct and cres-
