G. commixta Warr. ( = epimitra Turn.). Only the $ known. Palpus very long and slender (somewhat 
over 3 times diameter of eye). Shape of cyanoconias but with the hindwing somewhat more crenulate. Whitish 
blue-green, with darker blue-green irroration and bands, the coloration much less contrasted than in the 3 pre¬ 
ceding; the few scattered metallic scales more silvery than blue; cell-marks indistinct, slightly elongate; bands 
ill-defined, rather more irregular than in cyanoconias but less so than in viridaurea; distal margin with appre¬ 
ciable dark dots at vein-ends. Angabunga River, British New Guinea, also known from Queensland and New 
South Wales. 
G. submixta Front (12 f). Structure as in commixta, shape more closely as in cyanoconias ; generally 
smaller than commixta, colour still more uniform (the ground-colour less mixed with white), cell-dots more 
sharply defined (though still green), terminal dots less so; postmedian band generally as narrow as in bicolor 
and similarly sinuous, though less extremely. Dutch and British New Guinea and Ceram. 
G. pervicax Front. Larger than submixta (26 mm), palpus rather less long, cell-dots and lines more 
strongly developed, the whitish lines rather deeply dentate, with the tips of the teeth purer white. Manusela, 
Central Ceram. 
G. smaragdina Prout. Shape nearly as in privata ; larger (29 mm) and of a lighter, brighter blue-green; 
palpus moderate, with 2nd and 3rd joint not greatly elongate; forewing with cell shorter than in privata, cell- 
dot yellow-green, postmedian yellow-green line more proximal, accompanied distally by white spots on the 
veins; costal edge speckled with purple-grey; both wings with a dark brown terminal line and buff fringes. 
Mount Goliath (the type) and Weyland Mountains, only 2 $$ known. 
G. lychnopasta Turn, is unknown to me. Nearest to calaina, the A antennal pectinations twice as long 
(about 12 times the diameter of the shaft), hindwing with the angle at the 3rd radial weak. The bluish green 
ground-colour is marked with extremely fine pale strigulation and some scattered lustrous green-whitish scales; 
lines faintly indicated in darker green, the postmedian pale-bordered distally; cell-dots fuscous, on the hincl- 
wing minute. Ebor Scrub, New South Wales. 
G. calaina Turn. Larger than centrophylla (11 d), the $ palpus longer, the cell-dots less black, the lines 
represented by white spots on the veins, the postmedian of the forewing straight. Queensland: Mount Tam¬ 
bourine. Subsequently recorded from Tasmania. 
G. centrophylla Meyr. (= angulata T. P. Luc.) (11 d). Palpus in both sexes rather short, with moderate 
3rd joint. Hindtibia of S not dilated. Not in danger of being confused with any other known species. Distri¬ 
buted from Brisbane to Tasmania. 
G. unicolor Warr. (11 g), from S. Flores, is based on 2 ^ and 1 $, all of them unfortunately entirely 
discoloured in relaxing; we figure one of the as it now appears. Structure nearly as in centrophylla, $ palpus 
a little longer; markings apparently similar but weaker, the cell-dot not blackened; the ochreous costal edge 
is in the <$<$ strongly, in the $ much more slightly, mixed with black-brown, recalling some Hemithea. Hindlegs 
lost in both the <$<$. 
G. coerulea Warr. (4 f). Palpus moderate, with moderate 3rd joint. Hindtibia of dilated. AS from 
the type locality (Upper Aroa River) are unknown, on which account I abstain from naming an apparent race 
from the Snow Mountains, of which the Tring Museum possesses 3 A (one from near Oetakwa River figured) 
and 9 $$. The name-typical $2, together with one from Sattelberg, have the white outer line thickened be¬ 
tween R 2 and M 1 ) (recalling some Anisozyga) and the terminal spots at R 3 enlarged; those from the Snow Moun¬ 
tains are similar to the A> only with a larger white spot at the tail of the hindwing. 
G. imitans Warr. (A = invidens Warr.). Larger than coerulea (4 f), apex of forewing rather more acute, 
tail of hindwing rather longer; costal edge of forewing more strongly dark-speckled. A without wiiite terminal 
dots; $ with the central white subterminal and terminal markings even larger than in that of coerulea. Anga¬ 
bunga River, British New Guinea. 
G. caudipunctata Warr. Perhaps merely a form of the preceding, almost agreeing in size and shape, 
though slightly transitional towards coerulea (4 f). $ scarcely distinguishable from that of imitans. A with the 
terminal white dots of coerulea A, including the enlarged one at tail of hindwing. Biagi and Hydrographer 
Mountains, British New Guinea. 
G. sublustris Warr. Similar to patara (11 h). Hindwing with distal margin less crenulate and tail 
shorter. The shades which accompany the white lines weaker, less yellow. Underside shining slate-grey, 
only with the costal edge of the forewing bright ochreous. Ron Island, only the A type known. 
G. patara is an outstanding species, with black face, rather elongate black palpus and bright ochreous 
underside. It is distributed throughout the Solomons and shows very interesting local variability. Unfortunately
