Closest to P. pulclierrimus, Smith: diifers in the thorax being 

 more closely punctured, and in the abdomen being smooth with- 

 out punctures : in colour it differs considerably; the scutellum is 

 black not yellow, the coxae and femora are black not rufo-piceous, 

 and the apical segment is black not yellowish white. It is also 

 a considerably larger and stouter insect than P. pulcherrimus . 

 Prom P. hasalis, Smith, it differs in being much slighter, and in 

 the colour of the legs and the markings on the head and face.
