closer to subcostal, discocellulars normal, 2nd radial rarely arising near 1st radial. In polyspila and privatei, 
which should perhaps form a separate genus, the foretibia has a small apical claw. A fairly numerous genus, 
exclusively Australian, the species generally rather large or of moderate size, mostly rare or of retiring habits. 
The larva, so far as is yet known to me, has an additional pair of claspers. 
(E. ochripennata Walk. (= gastropacharia Walk.) (11 as gastropacharia). Rather approaches the ochripenna- 
preceding genus in shape, though the distal margin is not at all crenulate. Colour apparently variable, the 
type more ochreous-reddish, the ab. gastropacharia browner on the forewing, more rosy on the hindwing. West 
Australia, only Walker’s types known to me. 
(E. decolorata Warr. differs from vinaria (1 k) in having the ground-colour grey, the first line of the decolomta. 
forewing reddish, only distinct on the costa, the cell-spot indistinct, the oblique line not dark-edged proxi- 
mally, an antemedian line present also on the'hindwing, purplish. Forewing beneath paler, with a much 
smaller purple posterior spot than in vinaria. Moreover, the hindwing is slightly more rounded, showing a 
rather closer approach to ochripennata, to which it may possibly be related in spite of the shorter wings and the 
presence of the purple spot beneath forewing. North Queensland. 
Ok vinaria Guen. (1 k). The type of the genus and one of the best-known species. Variable in vinaria. 
colour but distinguished by its strong vinous or purple suffusions and by the strong dark-grey lines which 
bound the pale yellowish lines on their approximated sides. Underside very variegated, the forewing beyond 
the middle with a large deep-purple spot reaching from the 2nd median vein almost to the hindmargin. The 
type form is bright vinous or rosy, the $ in general darker or more brownish than the $. — decora Walk, decora. 
is a lighter form of the prevalent in Victoria. — The larva lias 2 black horny processes on the metathorax 
and 2 smaller conical yellow protuberances on the 8th abdominal. Feeds on Hakea, perhaps also on other plants. 
Distributed from South Australia to N. Queensland. 
(E. orthodesma Lower (= pallidula T. P. Luc., pallida Warr.) (1 1). Closely related to the preceding erthodesma. 
but paler and lacking the dark-grey lines; the yellowish oblique line reaches the costal margin rather farther 
from the apex. Underside less variegated, with the markings narrower. Queensland and West Australia. 
(E. erubescens Prout. Forewing a little broader than in vinaria (1 k), hindwing less truncate at apex, erubescens. 
Fleshy-ochreous, the antemedian line and cell-mark wanting, the double postmedian pale yellowish (proximally) 
and brownish red (distally) arising at costa close to apex, faint at first but mostly very strong. Founded on 
a single $ from Manly, New South Wales, captured in March. 
(E. niphosema Lower. Founded on a £ from Perth, West Australia, taken in November. Syste- niphosema. 
matic position doubtfid, as it is said to have antennal pectinations as long as the diameter of the shaft. Wing- 
expanse 50 mm. Forewing dull ochreous-carmine, more suffused with carmine in central area, costal edge 
wholly of the latter colour; a well-defined snow-white, slightly dark-edged spot in cell; a large dusky spot on 
discocellular; a dark, slightly excurved post-median line at three-fourths; a row of subterminal dark spots. 
Hindwing with termen moderately rounded; greyish-oclireous, broadly shaded with fuscous-purple distally. 
<E. vetustaria Walk. (= digglesaria Guen.) Very distinct from all the other species known to me, the vetustaria. 
hindwing having the distal margin prominently toothed at the end of the 3rd radial. Rather dark purple- 
grey, the pale lines accompanied on their approximated sides by blackish vein-dots, a faint dark median 
line present, rather closely approximated to the postmedian. Tasmania. 
(E. quadrigramma T. P. Luc. The 2nd subcostakvein of the forewing is free (A. J. Turner, in guadrigram- 
litt.) and both wings have the distal margin dentate towards the anal angle, but the former of these characters 
is shared by subu.staria and the latter by vetustaria and Lucas’ proposed new genus Galanageia has not been adop¬ 
ted. Ochreous fuscous, suffused with light lilac; costal margin of forewing strigulated with black and suffused 
with ferruginous; cell-spot large, light bluish grey, edged with ferruginous and containing proximally a hya¬ 
line dot and a lunular ferruginous-bordered figure; an oblique ochreous, proximally darker-bordered band 
from 5 / 6 costa; terminal line ferrous, conspicuously edged with ochreous; fringe ochreous, spotted with ferrous. 
Hindwing similar, the cell-spot quadrate, cut by the ochreous band. Brisbane. 
(E. polyspila Lower (= guttilinea Warr.) (1 k). One of the smaller species of the genus. Variable, but polyspila. 
always recognizable by the white costal spots; commonly also the posterior ones are white and sometimes even 
some of those in the middle of the wing; in any case the macular character of the markings is distinctive. — 
Larva rather stout, with the head relatively small; a pair of rudimentary claspers on the 5th abdominal seg¬ 
ment; dorsal area bright red, with pale yellowish dorsal and lateral lines. — Queensland.
