pectus and the prothorax, but slightly thinner, the two edges of the 
tibize 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 prothoracie 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 tibiz sharply bi-dentate outwardly, the apical tooth 
especially strong and long when not worn out, inner spur long, 
slender, those of the hind tibiz 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 faleate, 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, faleate 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 104-13} 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 Reinet, 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. 
vertumnus.
