476 DESCEIPIIONS OF AUSTEALIAN MICEO-LEPIDOPTERA, 



blotcli and hindmarginal band, but this blotch and suffusion are 

 often wholly absent ; rarely a minute dark fuscous dot in disc 

 before middle: cilia on hindmargin fuscous-purple, with an 

 indistinct dark grey line, towards tips yellowish, at apex and anal 

 angle wholly grey, on costa yellow. Hind wings rather dark grey, 

 lighter towards base, cilia grey. 



The bright yellow forewings distinguish this species from all 

 but Tl. paralyrgis, which has also yellow hindwings. 



Larva stout, slightly tapering at both ends ; rather light 

 purplish-grey or reddish-grey, spots minute, blackish ; dorsal, 

 sub-dorsal, and interrupted spiracular lines very irregular, slender, 

 grey- whitish ; other irregular scattered grey- whitish marblings on 

 sides ; second, third, and anal segments sprinkled with blackish 

 dots ; head greyish- ochreous, marbled with ochreous- whitish. 

 Peeds amongst spun together leaves of Eucalyptus tereticornis, 

 several larvae together forming an irregular nest of web and dis- 

 coloured leaves ; pupa in same position. These larvae are found 

 in August, and are extremely easy to rear ; the images appear to 

 emerge irregularly from August to November. 



Common round Sydney and Melbourne, but hardly ever met 

 with in the perfect state. 



Types of this species stand in the British Museum as Oecophora 

 semiruptella, AValk., 684?, but the description is obviously not 

 drawn from this species, the ground colour being stated to be 

 between brick-red and rose-colour, and all the details inconsistent; 

 some error must exist, and Walker's name must be wholly rejected 

 as unidentifiable. 



42. Hel. pliylarclia, n. sp. 



Magna, alis ant. griseis, angulum analem versus late purpureo- 

 suffusis, margine costali roseo, puncto disci saturatiore; post,
