428 STUDIES IN AUSTRALIAN NEUROPTERA, viii., 



men, with the largest measurements given in the above descrip- 

 tion, as allotype; loc. Woy Woy, N.S.W., Nov. 6th, 1918. 



Besides these, there are two other males in the British Museum 

 Collection, one in the Collection at Cornell Univ. (venation 

 figured by Comstock, i, fig. 170), a number in Mr. Luke Gallard's 

 collection, and thirty males and six females in my own collection, 

 all from Woy Woy. I have also a large number in alcohol, and 

 have distributed set males to many correspondents. 



Habitat: Sandy places along the coast of New South 

 Wales. Woy Woy, abundant during first half of November in 

 the bush near the Ocean Beach. Jervis Bay, abundant at same 

 date around the Naval College.* The males, which are much 

 more abundant than the females, assemble around the latter at 

 dusk, on tree-trunks or fence-posts, running actively about like 

 Cockroaches, or flying wildly round like Hepialid Moths. In 

 the air, both sexes appear of a very pale, almost whitish colour. 



Genus Heterithone, n.g. (Text-fig. 1, c-m). 

 Differs from Iihone only in the possession of two or more ap- 

 parent radial sectors in the forewing. 

 Genotype, Ithone fulva Till. 

 Habitat: Sandy places in Eastern Australia. 

 This geilus contains three species, which may be separated by 

 the following key : — 



'Dark, fuscous species of large size, with the appendages of 

 the male of enormous size, pointed apically, and almost as 



broad as long when viewed laterally H. megacerca, n.sp. 



Paler species, with males of smaller size, and their append- 

 ages of normal forcipate type 2. 



'Abdomen dull fulvous ; the wings with a tinge of mauve. 



Stradbroke Island, Queensland H. fulva (Till.). 



Abdomen pale oclneous, the wings very pale, not tinged 



with mauve. Victoria and Tasmania //. pallida, n.sp. 



Heterithone fulva (Till.). (Text-fig. 1, c-e). 

 Ithone fulva Till., These Proceedings, 1916, xli., Part 2, p.279,

* I have to thank my friend Lt. Commdr. Paymaster L. H. Mosse- 

 Robinson for this observation.
