The black markings of the elytra are arranged almost as in P. signaticornis 

 (Chevr.). The lateral spot underneath the shoulder small and rounded, the second 

 macula in front of the middle transverse, neither reaching the outer margin nor 

 the suture, and broadest towards the suture ; the lateral postmediau patch also 

 transverse, touching the outer margin, and its discal part somewhat bent towards 

 the tip of elytra ; the postmediau sutural spot rounded, and placed in front of, 

 but close to, the discal part of the postmeilian patch.
