92. Genus : Ompliacodes Warr. 
Palpus slender, but of moderate length. Antenna of <$ pectinate, of $ subpectinate. Hindtibia with 
all spurs, that of the dilated. Wings smooth-margined; in the venation the outstanding feature is the anasto¬ 
mosis of the costal of the hindwing with the cell, to its middle or beyond. A rather loosely-knit African genus 
(see Vol. 16, p. 42) but with an Indian genotype. 
0. directa Walk. (= gracilis Btlr.) (14 b). The only Indian species with the facies of the Syndromodes 
group of Africa — vivid green with the white markings very weak, the fringes white. Walker’s type was, 
as usual, rather badly localised (“Hindostan”), Butler’s was from Dharmsala; the species is not rare in Sikkim. 
93. Genus: Euloxia Warr. 
Palpus short, but with the 2nd joint rather strongly rough-scaled beneath, terminal joint minute. 
Antenna of with long pectinations. Hindtibia not dilated, in both sexes with 4 spurs. Abdomen not crested. 
Forewing with 1st subcostal arising from the cell, anastomosing slightly with the costal and very generally 
with the 2nd subcostal. Hindwing with costal closely approximated to cell near base, rather gradually diverg¬ 
ing. An Australian genus, perhaps nearest to the section of Hemistola in which the palpus is short and the 
antenna of the $ non-pectinate. Most of the species are rare or local and in several cases we are only able to 
cpiote the published information regarding them. 
E. argocnemis Meyr. “24 mm". Hindwing with termen slightly bent at 3rd radial. Both wings bluish 
green, without lines, fringes ochreous whitish, costal edge of forewing whitish ochreous, at base ferruginous. 
Face deep ferruginous, vertex pale, with a ferruginous line. Perth, W. Australia, only the type $ known. 
E. pyropa Meyr. Paler, with the hindwing “green-whitish”, its distal margin unevenly rounded. Dis¬ 
tinguishable from argocnemis by its orange head, discolorous hindwing and perhaps by its green forecoxa, that of 
argocnemis being silvery white. Perth; a race (?) from Victoria. 
E. beryllina Meyr. Head also orange, but with a green linear mark on each side of face and 2 green dots 
on the crown. Forewing brighter (“emerald green”); hindwing whitish green but — unlike that of pyropa — be¬ 
coming white at costa proximally. Founded on 1 $ from Geraldton, W. Australia. 
E. ochthaula Meyr. Rather smaller (“20—22 mm”), face brown, crown green, legs predominantly 
white. Forewing yellowish green, costal edge whitish buff except at base and towards apex; hindwing white, 
only faintly tinged with green. Carnarvon, W. Australia, among Eucalyptus. 
E. hypsithrona Meyr. (12 d). Unlike all the foregoing not only in its somewhat larger size and more 
blue-green forewing but especially in the presence of the two white lines, the postmedian also showing on the 
paler hindwing. Head green, between the antennae white. New South Wales: Mount Kosciusko, 5000 feet. 
E. leucochorda Meyr. (14 b) differs from hypsithrona in the very acute angulation of the 1st line of 
the forewing and the somewhat irregular shape of the hindwing. Tasmania. 
E. isadelpha Turn. “<$, 29 mm”. Closely allied to fugitivaria. from which it differs in the shape of the 
line of the forewing. This is sinuate and finely dentate, arising near the costa at about % the wing-length. 
Hindwing pale bluish green, becoming whitish towards costa and base. Antennal pectinations about 5 times 
diameter of shaft. Founded on 1 $ from Waroona, W. Australia. 
E. fugitivaria Guen. (= intacta Walk., obliquissima Walk.) (14 b). Recognizable by the single, weak, 
oblique line of the forewing and the whitish-green hind wing, which only at its margins assumes the brighter 
green of the forewing. Tasmania (the type locality) to Queensland. 
E. mcandraria Guen. (12 f). The commonest species and very distinct in its sharply white and markedly 
sinuous lines, the reddish-ochreous costal edge of the forewing, etc. Face bright red. Tasmania and Victoria. 
94. Genus: Mixochroa Warr. 
An offshoot of Euloxia, with rather small eye, stronger anastomoses of the subcostals of the forewing, 
longer approximation of the costal of the hindwing to the cell and some slight differences in shape and facies. 
Erected for the one species here given, which Turner regards as a slightly aberrant Euloxia. 
M. gratiosata Guen. (12 g) differs from all other Australian Hemitheinae in the orange-yellow hindwing. 
Tasmania (loc. typ.) and Victoria.
