NataL 2 2 (Coll. W. W. Saunders). 
This form, which is not to be confounded with Pompilus 
(recte Salius) widipennis, Smith (Jour. Linn. Soc., 1858, 
p. 98), is very closely allied to P. vindicatus, Smith, differ- 
ing from it in the broader and longer median segment 
which is also more rounded above. In P. vindicatus, the 
median segment is laterally compressed so as to form a 
slight longitudinal hollow on each side above.
