Section II. 



A sbarp shoulder-spine at the broadest part of the hood, behind whieh 

 the converging sides are armed with very numerous short spines or 

 blunt teeth, and are sometimes hardly more than crenulated.

Male. — Yellow, brown, or of a rich russet colour ; front of 

 head waved, always distinctly indented in the middle. Hood 

 with the lateral angles strongly projecting and the lateral 

 spines large ; apex of hood pointed. Front lobe with 3 teeth, 

 the first broad, sometimes divided in two, making 4 ; middle 

 lobe with 2 teeth and sometimes a small one between ; hinder 

 lobe with each alternate tooth before the lateral angles, and 

 generally each third tooth behind the angles, larger than the 

 others ; hinder lobe with a smooth central carina, obsolete 

 behind ; tegmina short, with the apex rounded otFj nervures 

 broad, the third cell below the mediastinal nervure from the 

 base with a large black ring surrounding a paler space, and 

 sometimes a few small white dots in black rings beyond. 

 (In the russet-coloured specimen every trace of the spots is 

 obliterated and even the neuration obscured ; but I see no 

 reason to consider it a distinct species.) Cerci long, slender 

 beyond the middle, and curved up at the extremities; sub- 

 genital plate nearly as long, broad, cleft at the extremity, and 

 the pointed ends upcurved. 



This is the species which Walker considered to represent 

 P. speci'osa, Thunb., which it resembles in the sharp lateral 

 spines and pointed hood ; but it is a much smaller insect and 

 the shape of the tegmina is quite ditferent. 



It is a variable species, and in this, as in several others of 

 which we have a series, I notice that the shape of the hood is 

 broader compared to its width in some specimens than in 

 others, showing that this is not a character of real importance. 



The Museum possesses four specimens, one immature. 

 Brunner's description is so short that I was at first in doubt 

 as to the identity of the species, and have therefore redescribed 

 it at greater length.
