spiracle ; an obscure interrupted blackish subspiracular line ; head

 lines oil crown : feeds gregariously in large nests of dense web, a 

 foot in diameter, amongst branches of Melaleuca genistifolia ; 

 January to March. 



Syntonarcha, n.g. 



Forehead oblique ; ocelli present ; tongue well-developed. 

 Antennae |, in $ filiform, simple. Labial palpi long, straight, 

 porrected, second joint clothed with rough projecting scales, 

 terminal joint moderate, with loosely appressed scales. Maxillary 

 palpi moderate, triangularly dilated with scales. Posterior tibiae 

 with outer spurs half inner. Fore wings with vein 1 simple, 

 cell in ^ abruptly contracted anteriorly so that upper and lower 

 margins are appressed together in disc from base to near middle of 

 wing, 2 from J of cell, 3 from much before angle, 4 and 5 approxi- 

 mated at base, 6 from a point with 9, 7 and 8 out of 9, 11 from 

 f of cell, bent upwards towards 12. Hind wings 1^ ; veins 4 

 and 5 closely approximated towards base, 7 out of 6 near origin, 

 anastomosing with 8 to middle. 



This is a very singular form, superficially perhaps more like 

 some of the Galleriadae than anything else, but quite peculiar ; 

 structurally it is undoubtedly to be referred to the Pyralididae, in 

 the neighbourhood of Gledeohia and Diploj^seustis.
