Antemiae in o ciliated. Palpi moderate or long, porrected, second 

 joint with projecting scales above and beneath, terminal short. Thorax 

 without crest. Forewings with 7 separate, to termen. Hindwings with 

 3, 4, 5 closely approximated at base, 6 and 7 stalked. 



A rather considerable genus of wide distribution, of which the species 

 are very similar and puzzling, and have been involved in much confusion. 

 Some of the species, and very possibly all, are attached to various species 

 of Juncus. There is often much variability, but the length of palpi, form 

 of forewings, and colour of hindwings are important and reliable characters.

$. 17-18 mm. Head and thorax light brownish-ochreous, sometimes 

 suffused with light brown-reddish, thorax sometimes mixed with grey. Palpi 

 2 J, whitish-ochreous sometimes partially suffused with light brown-reddish, 

 two oblique bands and scales of second joint beneath suffused with grey, 

 base whitish. Abdomen pale grey or whitish-grey. Forewings elongate, 

 narrow, posteriorly slightly dilated, costa slightly arched, apex obtuse, 

 termen straight, oblique ; pale brownish-ochreous, sometimes much suffused 

 with ferruginous, variably sprinkled or sometimes largely irrorated with 

 fuscous, veins posteriorly sometimes marked with fuscous lines ; costa 

 with short oblique strigulae of dark-fuscous irroration, between which on 

 posterior half are longer oblique leadeii-metallic marks, some of which 

 are sometimes continued as indistinct irregular striae across wing ; some- 

 times a broad suffused median streak of blackish irroration from base to 

 apex, or in its place a longitudinal series of several irregular black spots 

 or marks : cilia pale ochreous or grey, more or less sprinkled with black. 

 Hindwings grey- whitish, apex somewhat suffused with grey ; cilia grey- 

 whitish, round apex greyer, with grey subbasal line. 



Hamilton, in January ; three specimens. Also widely distributed in 

 Australia, but the above description is taken solely from my New Zealand 

 examples.
