eyes oval situated midway between the lateral angles of the occiput 
and the base of the mandibles. Thorax truncate in front, the sides 
nearly parallel, slightly narrowed posteriorly, bluntly tuberculate in 
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, 
bluntly dentate in the middle, 2nd segment long beneath,

Length 9 17 mm. 
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 2 B. astarte, Smith, and &. pythia, Smith, in the 
unmarked 2nd abdominal segment and in the form of the 
ventral carina of the Ist segment; from 4. comparata, 
Smith, by the latter character, by the narrower head and 
by the coarser puncturation.

The example from Salisbury is marked as the type of 
the following description — 
?. 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.
