156 DESCRIPTIONS OF AXTSTRALIAN MICRO -LEPIDOPTERA, 



contracted and produced to middle of hind-margin ; first dorsal 

 spot small, close to base ; second and third long, acute-triangular 

 very oblique, second sometimes confluent with first on margin ; 

 fourth before anal angle, obtuse-triangular, not oblique ; fifth on 

 hind-margin above anal angle, elongated along margin, some- 

 times confluent with fourth ; a small white spot above middle of 

 wing between second and third costal streaks ; a curved white 

 streak immediately before apex, enclosing a round black apical 

 spot ; cilia yellowish round apex, with two crimson hooks, thence 

 dark fuscous-grey. Hind-wings and cilia dark fuscous-grey. 



Somewhat less brightly coloured than /orwios^, but even more 

 elegant. At first sight the two species are very similar, and both 

 are somewhat variable, but within constant limits; for the 

 identification of this species I should lay stress upon the broader 

 wings, the frequent (but not invariable) suffusion with fuscous- 

 grey, the irregular crimson spotting of the thorax, the head white 

 rather than yellow, and the detailed differences in marking, 

 especially the presence of several additional small spots, the 

 absorption of the spot on the fold by the second dorsal streak, 

 and the termination of the dark costal streaks not on hind-margin 

 but in loops before reaching it. The species is also widely 

 distributed, and has the same habits as the last ; taken at Sydney, 

 Parramatta, Bulli, and Brisbane, from August to November, in 

 January, and March.
