STUDIES IN AUSTRALIAN NEUROPTERA, iv., 



Thorax brown above, with short, blackish hairs, dull 

 fulvous beneath; prothorax massive, wider than head. Legs dull 

 fulvous, densely clothed with short, dark brown hairs; tibial 

 spines straight, black, blunt, very short compared with first 

 tarsal joint (Plate xii, fig. 3), the latter nearly as long as the 

 other four joints put together. Between the claws is a large 

 empodium or jmlvillus (Text-fig. 1), formed of a single projecting 

 piece, cylindrical basally, bilobed distally, but on the dorsal side 

 only; below the lobes is seen a somewhat irregular black mass, 

 which appears to be the dried, gummy exudation from the lumen 

 of the organ. There can be little doubt that the pulvillus is 

 essentially an adhesive disc, which, with the aid of a sticky 

 secretion, enables this heavy-bodied insect to walk safely on 

 slippery surfaces, and to rest for long periods on the outside of 



foliage.

Text-fig.l. — Tarsal claws and empodium of It hone Jul m, n.sp.,(x30): 

 a, dorsal view; b, ventral view; c, nearly profile view. 



Abdomen subcylindrieal, tapering slightly towards apex; 

 in profile, segments 3-7 somewhat swollen. Colour dull fulvous. 

 Appendages: superior strong, forcipate, 2mm. long, pale brownish, 

 with short hairs; inferior OS mm. wide, rounded, dark brown, 

 hairy (Plate xii., figs. 4-6). 



Wings pale semi-transparent testaceous, with a tinge of 

 mauve towards costal border. In Plate xii., fig.l, the radius 

 and subcosta appear to be fused, but actually R stands on a 

 high ridge, with Sc sunk far beneath it, so that the two come 

 into line when viewed from above. (In /. fusca, R and Sc are 

 separately visible, owing to the greater breadth of the wing). 



The peculiar flattened head, sessile upon the large prothorax, 

 the crossed mandibles, short maxillaiy and labial palpi, and the
