Four specimens; adult male and female, two immature individuals; 

 Zulu Mission, South Africa. [A. N. S. Phila.] 



On comparison with these specimens, P. amarce Rehn^^ from western 

 Gallaland is seen to be a very distinct species. The two forms, which 

 occupy quite different regions, may be separated as follows: 



A. — Pronotum with the paired tubercles by the posterior margin 

 distinct and dentiform; head with the frontal process considerably 

 longer than the height of the clypeus ; costal margin of the tegmina 

 one and three-fourths millimeters in greatest width,
