1598 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 
arched, apex rounded, hindmargin obliquely rounded; yellowish- 
white; a fuscous basal patch, with blue-grey reflections, not 
reaching costa, extending on inner margin to outer edge nearly 
straight, cut by a slender whitish line on fold ; a very broad 
nearly straight fuscous-grey fascia, with blue-grey reflections, from 
costa before middle to inner margin beyond middle, its anterior 
half on upper ^ bright yellow-ochreous sufifused anteriorly into 
groundcolour and posteriorly into colour of fascia ; a very fine 
denticulate silvery - white line, crossing fascia obliquely from 
middle of its costal end to above middle of posterior side ; an 
apical patch, nearly straight-edged anteriorly, extending along 
hindmargin to near anal angle, glossy grey beneath, changing 
gradually upwards into yellow-ochreous ; thence suflused into 
groundcolour, its hindmarginal edge bluish-grey ; cilia dark grey, 
on costa changing into pale ochreous, on anal angle whitish. 
Hiedwings rather deep ochreous-yellow, apex and upper half of 
hindmargin narrowly suflused with dark fuscous ; cilia ochreous- 
yeUow, on upper half of hindmargin dark fuscous. 
Bathurst (2500 feet), New South Wales; one specimen in 
November ; I have seen a second, probably from Victoria. It is 
one of the finest of the Oecophoriclas ; yet there can be no doubt 
that it is coloured in elaborate and faithful imitation of the drop- 
pings of a bird ; the alternating eflects of white shading through 
yellow into brown, the glistening film of the darker portions, and 
other details are strictly reproduced.
