100 DESCRIPTIONS OF NEW SPECIES. 



P. afzeliana is. unknown to me, but seems to differ from P. 

 viUigera by the thorax having but two black spots, and by the 

 head having two distant occipital spots instead of two confluent 

 frontal ones, and by the vitta of the elytra being more sinuate, 

 and shorter, and by the apex being black.
