 the middle, thorax posteriorly truncate ; legs stout, posterior tibiae 

 with a single row of four or five long spines. Abdomen sessile, very 

 massive, basal segment disciform, short, ventral carina short,

Described from a single example. 



The females of different forms of Barymutilla are in 

 many cases very like each other, the markings of the 

 abdomen being very similar. The present form differs 

 from ^ B. astarte, Smith, and B. i^ythia, Smith, in the 

 unmarked 2nd abdominal segment and in the form of the 

 ventral carina of the 1st segment ; from B. comparata. 

 Smith, by the latter character, by the narrower head and 

 by the coarser puncturation.

Natal : Durban ^ (G. F. Leigh) ; Rhodesia : Mashona- 

 land, Salisbury 5000 ft. $ : Dec. 1902 (G. Marshall). 



The example from Salisbury is marked as the type of 

 the following description — 



9 . In form and sculpture identical with B. comparata, Smith, 

 differs only in that the 2nd abdominal segment is not unmarked 

 but bears two parallel round pubescent white spots on its apical 

 margin, one on each side of the middle, from each of which a short 

 very slender line of similar pubescence extends outwards. 



Length $ 12-14 mm.
