262 DESCRIPTIONS OF ATTSTRALIAN MICRO-LEPIDOPTEKA, 



hind-margin ; 1 furcate at base, but lower sometimes partially 

 obsolete. Hind-wings with 8 veins, sub-costal obsolete before 

 middle ; 5 and 6 stalked, one to either side of apex. 



This genus appears to be of some extent; it is subject to 

 variation with regard to the scaling of the labial palpi, which 

 are sometimes densely rough-haired, but the gradations do not 

 admit of further division. The neuration throughout the genus 

 is uniform ; vein 1 of fore-wings is always furcate at some 

 distance from base, but the lower branch is sometimes only 

 distinct at its origin. The width of the fore- wings also vaiies. 

 The habits of the imago are retired and sluggish; in repose 

 they sit flatly appressed to the surface, with the apex of the 

 fore-wings bent upwards. Though not brightly coloured, they 

 are elegantly marked. 



The larva of one species only is known to me ; it is 16-legged, 

 without peculiarity, and feeds in the seed-heads of one of the 

 ZiliacecB ; the pupa is placed in a slight cocoon amongst refuse 

 in the seed-head.
