3'2S STUDIES IX AfSTRALtAX VEt-ROPTERA, IV., 



Thiseitraordinary insect is clearh- a highly specialised offshoot 

 from the more normal form represented in Trichoma. The very 

 narrow and elongated wings, with long fringes, mark it off from 

 all otiier Neuroptera. 



Puslscripl, added May 1st, 1916. — tSince tlic completion of this 

 paper, I have received from ^Jr. Luke Gallard, of Epping, N.S. W., 

 a living specimen of a tine new species of ^tenobieUa, Avhich he 

 captured while beating bushes and low trees at Kenthurst, 

 N.S.W. Tliis remarkable insect, when alive, rests with its wings 

 forming a steep roof over its back, and projecting far bevond 



tlie end of its body. When 

 resting on a twig, the antenna- 

 are directed straight for- 

 wards, while the body and 



wings are held rigidly at an 



angle of about 30° to the 

 Text-fit;. 1 1.- plane of rest. As the wings 



are a dull brownish colour 

 with irregular grey markings and numerous hairs, the effect pro- 

 duced is that of a broken-off' stump of a small side-twig. The 

 principal factor in the success of this disguise is, of course, the 

 length of the wings. A pencil sketch, which I made of the 

 insect at rest, is reproduced in Text-Hg.ll. I append a short 

 description of this new species, which ] have dedicated to its 

 discoverer.
