tate ; antennae slender, third joint not as long as the next two combined, 

 seventh longer than wide, eighth sliorter, slightly wider, slightly trapezoidal, 

 a little longer than wide, club elongate, slender, compact and parallel ; ninth 

 joint obconical, slightly longer than wide, longer than the tenth, and two- 

 thirds as long as the eleventh, the latter oval, three-fourths longer than wide, 

 not constricted, narrowly rounded at apex. Prothorax slightly more than 

 twice as wide as long, length equal to apical width ; basal lobe very feeble ; 

 basal bead obsolete ; punctures almost obsolete. Scutellum ogival, two-thirds 

 wider tlian long. Elytra distinctly longer than wide, ratlier narrowly rounded 

 at apex ; sutural bead entirely wanting ; discal stria very deep and strongly 

 impressed, coincident with the suture at the apex, disappearing at basal 

 fourth ; surface smooth, highly polished, without reticulation, the punctures 

 of the series simple, very minute, distant and excessively feeble, not becoming 

 more distinct at the sides. Abdomen feebly reticulate in wavy broken lines, 

 sparsely, asperately punctate, a transverse row of punctures along the apex 

 of each segment more evident, coarsely pubescent. Legs moderate ; posterior 

 tibial spurs very small, slender, not very unequal ; corresponding tarsi 

 slender, nearly three-fourths as long as the tibiae, basal joint scarcely one- 

 half as long as the second, the articulation perfectly free and mobile. Length 

 1.9-2.4 mm.

The metasternal process is rather narrow, extending about two- 

 thircls the length of the coxse,. the mesosternum being strongly 

 developed in front of it, and slightly tumid. The post-coxal plates 

 are narrowly and very feebly prolonged behind. 



This common species, which seems to vary considerably in dis- 

 tinctness of coloration, is quite different from the European consi- 

 milis, in form, size, coloration, and especially sculpture. The entire 

 surface of the European insect is minutely, but distinctly strigilato- 

 reticulate. 



S. Tiduus n. sp. — Broadly oval, feebly attenuate behind from anterior 

 third, one-half longer than wide, obtusely rounded at apex, highly jwlished, 

 rufo-piceous, each elytron obliquely paler at apex ; under surface, legs and 

 antennae paler and more flavate. Head almost completely impunctate ; antennae 

 rather long and slender, third joint slightly shorter than the next two togetlier, 

 fourth a little shorter than the fifth and equal to the sixth, club rather elon- 

 gate, becoming broader from base to apex, the eleventh joint robust, the com- 

 pressed apex rather transversely truncate and subangulate at the sides, very 

 much wider than the ninth. Prothorax not definitely punctate ; basal lobe and 

 its beaded edge almost obsolete. Scutellum small, ogival, scarcely one-half 

 wider than long. Elytral punctures and discal stria nearly as in apicalis, the 

 punctures more nearly obsolete, and more decidedly visible in the lateral 

 series. Abdomen rather sparsely, coarsely pubescent, asperately punctate. 

 Legs rather short and slightly robust ; posterior tibial spurs short, subequal.
