est point, all the otlier bristles being eitlier very thin or 

 ver}'- short, or both. The manubrium of the clasper as well 

 as the internal (vertical) arm of the ninth sternite are not 

 plahily visible in the only specimen, and we therefore abs- 

 tain from describing and figuring them. The horizontal 

 arm of the ninth sternite (IX. st.) bears in the apieal third 

 nnmerous bristles on the ventral surface, these bristles being 

 flanked at the ventral edge by a row of about 7 short, stout, 

 sharply pointed bristles, of which the distal ones are curved 

 like a snake's fångs. 

 Length 2 mm.

A near ally of S. simsoni Roths. (1905) with which it 

 agrees, particularly in the arrangement of the bristles on 

 the thorax and tibiae, but is easily separated from simsoni 

 by the anal tergite not bearing numerous stout spiniform 

 bristles. 



Head. Helmet similar to that of 8. simsoni, with a 

 comb of 15 spines on each side; a genal comb of 7 more or 

 less pointed spines, besides a long bristle-like spine placed 

 behind the vestigial eye; in front of the eye one long and 

 strong bristle, above this bristle two small ones, and below 

 it three small bristles, of which the one placed near the 

 genal edge is the largest, and further frontally a few more 

 small bristles. The hairs in the dorsal (median) groove of 

 the occiput are erect (accidentally) forming a kind of måne.
