above ; legs, antennae and under surface dark testaceous. Head finely and 

 strongly reticulate, the reticulations rounded and not tending in the least to a 

 linear arrangement ; antennse moderate, coarsely setose, fourth joint shorter 

 than the fifth, club ratlier robust, moderate in length, the eleventh joint but 

 slightly longer than the ninth. Prothorax more than twice as wide as long ; 

 base transverse, without a median lobe but slightly sinuate for a short distance 

 each side of the scutellum ; bead very minute ; surface not visibly punctate, 

 finely reticulate, the reticulations tending to a transverse arrangement. Scu- 

 tellum ogival, nearly twice as wide as long, transversely reticulate. Elytra 

 finely and very strongly reticulate over the entire surface, the reticulations 

 tending to form very broken transverse wavy lines ; punctures of the series 

 almost completely obsolete although perceptible, scarcely more visible at the 

 sides, where they become slightly wider but not at all crescentiform ; discal 

 stria feeble, coincident with the suture at the apex, very short, disappearing 

 in a row of feeble punctures at about the middle. Abdomen strongly reticulate, 

 sparsely, finely punctate, very sparsely pubescent. Legs moderate, tibise 

 slender ; posterior spurs small, subequal, the corresponding tarsi about two- 

 thirds as long as the tibise, with the basal joint more than one-half as long as 

 the second. Length 1.4 mm. 



New Jersey (Cape May). 



The nietasternal process is very wide, broadly rounded at apex, 

 the mesosternum in front of it rather short, transverse and but very 

 slightly tumid; the prosternal process is wide, and the spinules 

 along its apical margin very short and widely distant. The surface 

 of the metasternum in the middle anteriorly is extremely sparsel}'' 

 pubescent, and not visibly punctate. 



The dark color and sternal structure will at once distinguish this 

 small species from nitidus, which it somewhat resembles in el^^tral 

 sculpture and punctuation, and the short very feeble discal stria 

 separates it from every other species of the genus known to me. 

 It appears, however, to resemble the Mexican Olibrus porrectus 

 Sharp, which is almost certainly not an Olibrus. 



S. COlivergeilS n. sp. — Somewhat narrowly oval, very convex, polished, 

 dark rufo-testaceous throughout, distinctly attenuate behind from the base of 

 the elytra, the ai)ex narrowly subtruncate and about one-half as wide as the 

 base. Head finely but rather distinctly punctate, more densely so toward the 

 eyes and base, not at all reticulate ; antennae moderate in length, third joint 

 rather shorter than the next two together, fourth shorter than the fifth, seventh 

 and eighth subequal in length, more robust, club very long and strongly de- 

 veloped, ninth and tenth joints equal in length, more acutely angular on the 

 anterior side which is more densely pubescent, eleventh nearly as long as the 

 two preceding. Prothorax ratlier long, not more than twice as wide as long, 

 highly polished, not reticulate, very minutely and rather sparsely punctate;
