STUDIES IK AUSTRALIAN NEUROPTERA, ii., 



followed by a dark brown spot, above which, slightly proxiraad, 

 lies a small, brown spot. In the cubital space, there are four, 

 elongated, narrow, blackish spots. At the apex of the wing, is 

 a large, irregular, transparent, orange blotch: a smaller blotch 

 runs in from the wing-border between this and the pterostigma, 

 and below it is a small, squarish, brown spot with a pale orange 

 centre-point. From the apex towards the angle of the falcate 

 border, lie four, transparent, orange blotches, with three, 

 irregularly placed, brownish spots lying proximad to them. 

 Along posterior margin of wing, a large, irregular, trapezoidal, 

 orange blotch occupies the middle, posterior angle, and is touched 

 above by black; half-way between this and the wing-base, is a 

 smaller, oval spot of the same colour. 



The hind wing shows very few markings, all distally placed, 

 and of a uniform brown, except for three, minute spots along 

 Sc + R. A large, reniform spot overlies R and Rs at level of the 

 angle of the falcate border, which itself is filled with a larger 

 and more irregular blotch. Pterostigma whitish, opaque, with 

 two, small spots near it. A rounded spot at apex, and two, 

 elongated marks on the falcate border complete the markings. 



Hah. — Cunderdin, W.A. A unique specimen, apparently a 

 male, but the abdomen is somewhat shrivelled.

This very beautiful insect is at once distinguished from the 

 other two spt^cies of the genus by its small size, and by the 

 beautiful and bizarre effect of its colouration, which suggests a 

 stained-glass window in old gold. It appears to be more closely 

 related to P. laceratus Gerst., than to the better known /*. 

 circidter Walker, owing to a closer similarity in the scheme of 

 wing-markings. From both these species, it differs in having 

 the forewing much less falcate.
