a moderately deep depression on each side ; the prothorax is of the 

 usual sub-trapezoidal form, moderately sinuate on each side of the 

 scutellum and strongly arcuate above it ; scutellum long and sharp, 

 grooved laterally ; elytra elongated, and narrowing behind ; sternal 

 process long, slanting slightly downwards, but with the cylindrical 

 apical part curving upwards without being, however, much hamate ; 

 anterior tibiae of $ dentate outwardly at the apex only, those of the 

 ? tri-dentate ; inner part of tibiae not pubescent but with seriate 

 hairs in both sexes ; hind femora of $ thickened but in a much 

 lesser degree than in Eccoptocnemis, and inner part of tibiae either 

 moderately or strongly serrate.

Light chestnut, with four black patches on the prothorax, and 

 two small ones on the scutellum, past the median part of the elytra 

 there is on each side a quadrate flavous patch the outer edge of 

 which is continued along the outer margin in the shape of a lateral 

 band which does not reach quite the posterior outer angle, the dorsal 

 part of the patch, which with its prolongation is not unlike a huge 

 zigzagged comma, is often sinuate, and either partly or completely 

 edged with black ; in some examples from the Transvaal the four 

 patches on the thorax, the hind ones of which are normally larger 

 than the anterior, have invaded the greatest part of the disk, and the 

 elytra with the exception of the outer margins, and also the 

 scutellum, are very dark brown ; head almost impunctate in the 

 male, closely punctate in the female, but the punctures on the 

 prothorax are few and more noticeable in either sex on the sides 

 which are slightly transversely sigillate towards the median part ; 

 scutellum impunctate ; elytra non-costulate and very obsoletely 

 seriate punctulate ; pygidium more conspicuously plicate trans- 

 versely in the female than in the male ; under side glabrous except 

 for a short pubescence on the anterior coxae, weakly punctate in the 

 male, but strongly and closely in the female ; the serration of the 

 inner part of the hind tibiae of the male varies greatly in individuals
