This form, which is not to be confounded witli Fompilus 

 (^recte Salius) iridipennis. 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 loncT^itudinal hollow on each side above.
