 this genus.

Male. — Green (type discoloured) ; front of head slightly 

 waved ; hood pointed, with long strong conical spines, gradually 

 diminishing in length hindwards, but without alternately 

 larger and smaller ones ; lateral spines much longer than 

 the others ; front lobe with 3, middle lobe with 2 teeth ; the 

 division between the middle and hind lobe, as well as the 

 central carina of the last, very slightly marked ; tegmina 

 gradually widening for three fourths of their length, when 

 the costa bends obliquely, and the inner margin at rather 

 more than a right angle to the apex, which is rounded off; 

 the three terminal branches of the principal nervure separating 

 close together, the upper and second nearly straight, gradually 

 diverging, the lower one bending downwards, and forking ju^t 

 on the upperside of the apex. Front femora with 6-Q spines 

 on the outer carina and 3-4 on the inner; intermediate 

 femora with 5 pairs (the middle spine wanting on the inner 

 carina of the right middle femur) ; hind femora with 8 or 9 

 spines (not counting the terminal ones) on the outer carina 

 and 5 on the inner. 



This specimen is considerably smaller than Brunner's type 

 of P. truncata ; but I should not be surprised if it ultimately 

 proves to be the male of that insect. It also much resembles 

 the figure of P. speciosa. Blanch, (nee Timnb.).
