a less distance than they are from the anterior ; they are separated from each other by a 
less distance than they are from the eyes. The clypeus and more or less of the pro- and 
mesothorax are rufous ; the calcaria rufous, as may be also the joints of the legs. The 
mandibles are rufous. In the female the narrowed basal part of the abdomen is slightly 
shorter than the dilated part ; in the male it is distinctly longer than it. The largest — 
specimens are 25 mm. long; the smallest male is 17 mm. The males have the wings 
clearer than they are in the females, the yellow tint not being so deep. 
Pérez (/.c. supra) states that this species is found in “Southern Africa, in the Islands” 
of the Indian Ocean and in India.” I have never seen the species in any of the collections 
I have examined from India or Malaya, nor does Bingham describe it in his work on the 
Hymenoptera of British India. I believe the species is confined to Middle East Africa 
and the East African Islands.

revision of the genus in the work cited above.
