/582 Mr. E. Eosenstock on Australian Lepidopfera. 



pubescent, dark fuscous ; palpi obliquely ascendant, black ; 

 proboscis strong, reddish amber-coloured ; thorax greyish 

 black, with lateral patches of white scales ; collar white ; 

 tegulse blackish, edged with long whitish hairs ; legs dark 

 greyish, hind tibiae and tarsi yellow ; abdomen deep yellow, 

 smoky black near base. 



Fore icings white, yellow-tinged along hind margin, with a 

 falciform blackish basal mark commencing upon costa, but not 

 reaching hind margin ; a black transverse line from costa at 

 two fifths of its lenglh, attenuated posteriorly; a well-defined 

 black circular discocellular dot, with a small blackish costal spot 

 above and an indistinct sagittate mark below ; an irregular 

 submarginal band with outward angular projections abutting 

 upon the narrow, blackish, hind marginal border. 



Hind wings pale stramineous yellow ; apex suffused with 

 black, and a small blackish discocellular spot. 



Expanse of wings 20 millim. ; length of body 7 millira. 



Philenora, n. g. 



An'ennaj of male strongly pectinated; palpi short, clothed 

 with appressed hairs, porrected, hardly projecting beyond 

 head ; face obtusely conical ; proboscis strong ; thorax sub- 

 ovate, moderately convex, with prominent collar and short 

 side tegulas ; abdomen slender, not extending beyond hind 

 wings in male, with strong anal tuft. Fore wings subtrian- 

 gular, with rounded apex, oblique outer and slightly sinuate 

 inner margins. 



Allied to Mosoda, Walk., but differing in the strongly 

 pectinated antennse, which are merely pubescent in the latter 

 genus, and in the neuration of the fore wings, vein 10 (second 

 subcostal branch) being emitted at upper angle of cell from 

 same point as 9 and the common stalk of 7 and 8, and 11 from 

 the anterior fourth of the cell ; whereas in Mosoda 10 rises 

 from the subcostal from before the angle of the cell, and 11 

 behind it from posterior third to half of cell. 



(18.) Philenora undulosa (J, Walk. 



Acontia undulosa, Walk. Z. c. xii. p. 797. 



Walker wrongly described the female of this species as an 

 Acontia. I was therefore obliged, in the absence of any other 

 corresponding Lithosiid genus, to create a new one for its 

 reception. 



The male of this species, besides difference of antennal 

 characters and smaller size, has the white ground-colour of the 

 fore wings somewhat obscured by grey, rendering the trans- 

 verse markings fainter. Expanse 22 millim.
