Hab. Western Australia ; two males in my own collection 

 brought over by Mr. Dulwulay. 



Very nearly allied to P. Erichs<mii, Lac, both in coloration 

 and in sculpture, it may however be at once known by the follow- 

 ing distinctive characters. The clypeus, which in P. Erichsoni! 

 is as broad as, or even slightly broader than long, is in the present 

 species distinctly elongate ; the antenna? are more robust, the 

 third and follo'W'ing joints being distinctly flattened, the third is 

 scarcely more than half the length of the fourth and fifth, these 

 joints being of nearly ecjual length — in P. Erlchsonli the third 

 joint is longer, and the third, fourth, and fifth gradually increase 

 in length ; the thorax in the present species is shorter, its broad- 

 est portion being nearer the apex than in the older insect.

 basi tibiisque (his apice exceptis) pallide rufo-piceis ; elytris

 lem positis, nigris. Long. 4|- lin.

 the body in length, second joint very short, third and fourth 

 each three times the length of the second, equal, second, third,

 longer than broad, cylindrical, slightly depressed on either side 

 the disk, sides constricted just behind the middle ; surface rugose,
