T. gigas Warr. is a large species with the apex of the forewing minutely produced, the markings very 
weak, the outer line, however, forming a very narrow whitish-green hand (about 1.5 mm wide). A very fine 
red-brown terminal line. Fringe white proximally, dark-grey distally. Hindtibia of $ dilated. Solomons: 
Tulagi (a small island off Ysabel) and Guizo. 
T. effata Prout. Almost as large as the preceding, similar in structure. The indistinct whitish post- 
median band is rather broader, rather more proximal, standing just beyond a minute dark cell-dot, and there 
is a second ill-defined band at the distal margin. Terminal line and fringe green. Batjan; also from Central 
Ceram. A specimen from the N. coast of New Guinea and one from Dampier Island perhaps differ racially. 
T. saturata Snell., from Celebes, is unknown to me, but appears to be similar to the preceding though 
with the $ hindtibia not dilated, the hindwing less bent at the 3rd radial, the whitish bands obsolete, a darker 
green line indicated between their positions. 
T. interalbata Prout (13 a) has the white bands broader and clearer than in effata and differently placed, 
occupying on the forewing approximately the position of the greener bands of that species. Dutch New 
Guinea. Also an example from Sattelberg in the Tring Museum. 
T. viridifascia Swinh. Another large species, with very broad white bands, on forewing 3, subbasal, 
median and subterminal, leaving 2 less broad bands and an apical patch green. N. Borneo. 
T. nivestrota Warr. (13 a) is a beautiful and unmistakable species, the white bands of the fore wing 
purer and more numerous than in any other, the abdomen broadly white dorsally. Distributed in New Guinea 
and more recently found in New Ireland. 
T. zebrata Warr. (4 f) is known by its duller grey-green colour, rounder hindwing and characteristic 
banded pattern. Its less long pectinations and less extremely oblique discocellulars show that it is transitional 
towards Prasinocyma, to which it should perhaps be transferred. New Guinea. 
63. Genus: Eretiiiopus Turn. 
Similar to Thalassodes. Hindtibia of $ thickened and without spurs, the tarsus abbreviated and densely 
rough-scaled; $ hindtibia with terminal spurs only. The known species are closely related. I have not seen 
the Port Darwin genotype (marinaria Turn., vix Guen.). 
E. retensa Prout. Closely similar to marinaria (13 a). Face perhaps rather brighter red. Hindtibia of 
slightly longer and broader. Hindwing slightly less angled; beneath without a trace of the coarse buff scaling 
of marinaria Philippines. 
E. marinaria Guen. (<$ = penicillata Walk.) (13 a). Distinguishable from nearly all Thalassodes, apart 
from the structure, by the complete absence of markings. £ hindwing beneath with coarse buff (or somewhat 
cinnamon) scaling proximally. Both the types were from Borneo; known also from Tana Djampea, Celebes 
and the Moluccas. 
E. discissa Walk, has the hindtarsus of the $ densely rough-scaled, which is not the case with the 
other species. Hindwing with a white cell-dot. Only definitely known from Lower Burma. A race, or close 
ally, from Dutch New Guinea has similar leg-structure. 
64. Genus: Prasinocyma Warr. 
A very extensive and not very homogeneous genus which is probably in need of further revision. 
Some of the species have nearly the facies of Thalassodes, from which they differ chiefly in the less oblique 
discocellulars of the hindwing. Some have the palpus almost as short as in the Australian genus Chlorocoma 
and perhaps intergrade therewith. A few rather thinly scaled species certainly intergrade with Gelasma (see 
above). The typical group, which is chiefly African, is perhaps only represented in the Indo-Australian 
Region by albicosta; but for the present we refer here all the species which show the general characters of 
the group and do not conform to the special distinctions of the outlying genera. 
Antenna pectinate in the $ but not in the $. Palpus moderate to longish, terminal joint in $ more 
or less elongate. Hindtibia with all spurs. Abdomen not crested. Frenulum short in the <$, wanting in the 
2. Scaling generally dense, coloration more or less bright green; hindwing rounded or with a short or moder¬ 
ate angle at 3rd radial, never strongly tailed; venation normal. 
P.peristicta West. Very slightly more bluish green than albicosta, rather more robust, without markings; 
hindwing with discocellulars somewhat approaching those of Thalassodes. Palawan.
