with traces of one basal, one antemedian and one median dark line, besides there are postmedian and subterminal 
lines flown together into a single dark line between the veins 1 and 2 before the anal angle. Distal margin

34. Genus: Ocnerla Hbn. 
To this genus, the characterization of which is stated in Vol. II, p. 131, beside the 15 palearctic species, 
also 1 Australian species not lying before us is said to belong.

Antennae brown, with pale pinkish-brown combs (7). Abdomen light reddish-orange. Legs whitish, anterior 
and middle tibiae mixed with black. Forewing triangular with an oblique, scarcely undulate, in the middle 
distinctly indented margin; ferruginous with five darker and feebly curved lines finely speckled dark grey, 
the two first being antemedian, the third postmeclian, the fourth and fifth undulate and subterminal; a blackish 
discal spot in the middle; margin partly hued darker. Hinclwing with a rounded distal margin and a long proximal 
margin, so that the anal angle appears to be extended; bright orange and with traces of two undulate, dark 
postmedian lines; the posterior third of the margin broadly brownish. — $: body and palpi ochreous-white. 
Antennae dark brown, pinnae 2. Legs brown. Forewing triangular with an oblique, almost straight border;

light reddish. The larva attains a length of as much as 73% mm, lives on Eucalyptus and pupates in February 
or March. — Pupa has a length of up to 30% mm. — Flying time January, February and April. Australia:
