whitish or whitish-ochreous. Fore wings tolerably broad, mode- 

 rately dilated, hind margin strongly rounded beneath ; varying 

 from brownish -ochreous to dark fuscous, darkest along costa ; 

 markings very variable or obsolete ; generally a small dark 

 fuscous or blackish discal spot at two-thirds ; sometimes another 

 obliquely above it near costa, and a third obliquely below it on 

 fold ; in the most distinctly-marked specimens there are two 

 transverse cloudy blackish-fuscous lines, the first from two-fifths of 

 costa to two-fifths of inner margin, strongly angulated outwards 

 above middle ; the second rising from costa before apex, curving 

 round and running to the median discal spot, thence continued 

 to the inner margin parallel to the first ; these lines are gene- 

 rally obsolete or absent ; a row of blackish spots on hind 

 margin ; cilia greyish-ochreous. Hind wings pure white, towards 

 apex more or less sufi'used with smoky fuscous ; cilia white, 

 smoky towards apex of wing. 



$ 14" — 17". Head, palpi, antennae, thorax, abdomen, and legs 

 white ; palpi little longer than head ; anal tuft whitish-ochreous ; 

 posterior tarsi externally fuscous-grey. Fore wings elongate, 

 tolerably broad, hind margin nearly straight, obliquely 

 rounded beneath ; satiny-white, sometimes more or less strongly 

 sufi'used throughout with whitish-ochreous ; cilia white. Hind 

 wings and cilia pure satiny- white. 



Extremely variable ; the (^ somewhat resembling gigantellus 

 (^ , but darker, the ? very distinct. 



Very common at Parramatta in February and March on the 

 river, the ? resting motionless on rushes, the $ more active ; 

 both come freely to light. The larva feeds in the cylindrical 

 stem-like leaves of Juncus prismatocar^us, growing in the water.

 Wings elongate, apex of hind wings reaching beyond anal angle 

 of fore wings. Hind wings with a basal pecten. Abdomen in J"
