Hab. Pang Tiac, Haut Mékong ; May 14, 1918. 
Described from a single female. 
Closely allied to the South Indian P. apollyon, Morl., 
but the stigma and veins are black, not fulvous as in 
apollyon, the front is more strongly concave and has a 
sulcus, the mesopleurz are more strongly and _ sparsely 
punctured and the sculpture of the abdomen is coarser. 
P. apollyon is without luteous apical margins on _ the 
abdominal segments.
