The colour of the thorax and elytra of the type is now 

 nearly testaceous. The thorax is strongly punctured in 

 front, and has a strong discoidal impression. The elytra 

 have seven costse, the alternate ones being rather indis- 

 tinct and irregular ; that next the suture is divided into 

 three near the scutellum. The apex of the elytra and the 

 abdomen are now wanting in the type specimen, which is 

 the only one I have seen.

There is nothing in the descriptions of these species to 

 show how they differ from each other and from P. rufi- 

 penne, of which I regard them simply as the sexes.
