reaches about as far as two-thirds of the distance along the 

 maxillte. 



Sternum. — Only a trifle longer than wide, broadly 

 truncate in front and narrowing to a point posteriorly 

 between the hind coxte, which are completely separated 

 thereby. It is broadest opposite the cox^ of the second legs. 



Abdomen. — Elongated, covered with soft, slender, plumose 

 hairs, all backwardly directed. On its ventral surface the 

 tracheal stigma is placed far forwards, being situated only 

 very slightly posterior to the mid-point between the genital 

 aperture and the bases of the inferior spinners.^ 



Spinners. — Inferior spinners widely separated, about 

 twice their own width apart. Superior spinners with the 

 apical segment about half the length of the basal one. 

 Colulus absent. The median and superior spinners arise only 

 very slightly posterior to the inferior spinners, especially in 

 the male, where the Avhole six are arranged almost in a 

 transverse line ; in the female the arrangement is roughly in 

 two transverse lines. 



Total length. — Adult male 3"5 mm. 



This genus in its spinner arrangement approaches the 

 group Hahniinae and will probably prove to be closely 

 related to some of the little-known genera of that group. 

 The tibial process of the male palp is very like that figured 

 by Simon- for Hahnia oreophila E. Sim. The position 

 of the tracheal stigma is also apparently an extreme condi- 

 tion of a tendency obtaining in various genera of this group. 

 I have placed Muizenbergia provisionally in the group 



' Since writing the above, I have examined a large female example 

 from St. James, near Cape Town (coll. J. H. Power). This clearly shows 

 that the median tracheal stigma is double, the actual openings being 

 connected by a sliort transverse furrow. The tufts of hairs shown on 

 E, text-fig. 1, mark the positions of these openings. Further, the lateral 

 eyes of each side are slightly raised on an obliquely disposed prominence.
