South African Coleopterous Fauna. 197 



the others black, and the antennae are long and somewhat slender, 

 the femora are slightly fuscous, the tibiae and tarsi flavescent ; the 

 frontal impressions are not deep, and the short sulcus is arcuate ; 

 prothorax as broad as long, arcuate laterally from the angle of the 

 anterior part which is nearly straight to about four-fifths of the length 

 where it is slightly narrowed but not sinuate, its greatest width being 

 across the median part, the basal outer angle is sharp, the outer 

 margin slightly reflexed, the lateral sulcus narrow and continued at 

 the base as far as the basal sulcus which is set close to the outer 

 margin, the space between the two basal sulci is numerously punc- 

 tulate, but the number of punctures vary in some examples, there is 

 no impressed arcuate line in the anterior part of the disk and the 

 sides of the posterior part are not depressed nor reflexed ; elytra 

 oblong with the shoulders slightly rounded and broader than the 

 prothorax at its widest part, the impunctate strias are moderately 

 deep, the intei'vals plane, the puncture on the side of the third 

 interval is median, and the edge of the outer margin and also the 

 epipleural fold are flavescent as in some species of Stenolophus ; 

 under side impunctate, metasternal episterna narrow, much longer 

 than broad ; posterior tibiae not deeply sulcate inwardly, first and 

 second joints of hind tarsi sulcate outwardly, fifth joint glabrous 

 underneath. 



I know of no South African species with which this species can 

 be compared. 



Length 4^-6f mm. ; width 2f mm.

Black, shiny, the elytra have a faint bronze tinge, the three basal 

 joints of the antennae are reddish, but the third one is somewhat 

 infuscate, the other joints are deeply fuscate, the femora also, the 

 tibiae are lighter than the femora, and the tarsi, especially the anterior 

 ones, are flavescent ; frontal sulci moderately long, arcuate ; pro- 

 thorax a little narrower at the base than at the apex, not much 

 ampliated laterally, but regularly arcuate for two-thirds of the length, 

 and oblique thence as far as the basal angle which projects, the 

 lateral sulcus is connected along the base with the deep basal sulcus 

 which is situated nearer to the outer angle than to the median 

 longitudinal line, and the space between these two basal sulci is 

 sparsely punctate, the sides of the posterior part are not depressed ; 

 elytra oblong, broader slightly past the not much rounded shoulders
