This species bears a close resemblance to P. unifasciata, Smith, ' Cat. 

 Hym.' iii. p. 145, but independent of a difference in the neuration of 

 the anterior wings, the armature of the legs is totally different : in 

 P. unifasciata the posterior tibiae are armed with long scattered spines, 

 not serrated, as in the present species.
