pectus and the prothorax, but slightly thinner, the two edges of the 

 tibiae have a conspicuous fringe of long greyish hairs ; clypeus finely 

 aciculate, straight laterally for a short distance from the base, thence 

 parabolic and deeply notched triangularly in the centre, the margin 

 is plainly reflexed, but the two angles of the incision are not 

 conspicuously tooth-like, the head is aciculate like the clypeus, the 

 suture between the two is noticeable if the hairs are removed, there 

 is no basal carina, yet there is a plain, slightly raised, transverse 

 elevation ; prothorax twice as broad as long, somewhat convex, 

 .ampliated laterally in the median part, but very broadly rounded 

 at the basal angle, the sculpture is completely hidden above 

 and under by the pubescence ; scutellum about equal in length 

 to the width at the base, also hidden by the prothoracic pubescence 

 .as well as by its own ; elytra glabrous, shining lightly, yet 

 somewhat coarsely and irregularly punctate, very faintly tri- or 

 •quadri-striate in the dorsal part, but having a very plain stria at 

 a short distance from the suture ; propygidium and pygidium closely 

 aciculate, more convex from the base to the apex in the male, more 

 triangular and distinctly depressed on each side in the female, the 

 two ultimate abdominal segments are very closely aciculate all over, 

 and the others closely along the two margins but much less so in the 

 centre ; anterior tibiae sharply bi- dentate outwardly, the apical tooth 

 especially strong and long when not worn out, inner spur long, 

 slender, those of the hind tibiae only very slightly more dilated 

 towards the tip in the female than in the male. In this sex the 

 shape of the claws differ much from that of the female, the upper 

 .apical tooth is falcate, and underneath there is an equally falcate 

 one, as in the genus Schizonycha, and in addition another nearly sub- 

 basal and falcate, and the base of the claw is only angular, whereas 

 in the female there is a simple, falcate upper tooth, a vertical, nearly 

 median, and a shorter, but plain, basal one. 



The shape of the genital armature of the male is very distinct from 

 that of the other species. 



Length 19-26 mm. ; width 10J- 13^ mm. 



Hab. The typical form with pale testaceous colour seems to be 

 confined to the Karroo proper or its close vicinity, in the Cape 

 Colony (Worcester, Fraserburg, Beaufort West, Victoria West, 

 Prince Albert, Graaf Eeinet, Humansdorp, Willowmore, Mossel 

 Bay, Uitenhage), but the form with light chestnut elytra occurs 

 in Namaqualand, Bushmanland and Damaraland. 



Boheman records this species from " Caffraria tota," but it seems 

 to me probable that this author mistook S. transvaalica for S. 

 vertummis.
