well stalked); cell-spot of hindwing transversely elongate, white, containing some dark-grey scales. Here may 
also he mentioned, with a view to stimulating research, 3 $$ in the Tring Museum, from separate localities 
in E. Java, which await their $ but may well be forms of acerbata. All are larger than the type (forewing 15 
to nearly 16 mm) and they agree together in having the 3rd joint of the palpus about as long as the 2nd, the 
2nd subcostal of the forewing stalked, their shape pretty normal, etc. Two nearly agree in coloration with 
acerbata , though the costal darkening (compare acmaea) is noticeable; one of these (from Djoenggo, Ardjoeno, 
4500 feet) has the cell-mark of the hindwing narrower than in acerbata <$, white, with some black scales about 
the radial fold (compare olivescens)-, the other (Nongkodjadjar, 4000 feet) has it as in brevipalpis (15f). The 
third 2 (Singolangoe, Tengger, 5000 feet) is lighter and brighter, without costal darkening, the cell-mark as 
in the Djoenggo 2- By the palpus, these four cannot represent races of olivescens. An extremely worn 2 from 
Trinidad, Baguio, Benguet (A. E. Wileman) may also represent acerbata, but is not worth describing. 
0. olivescens Wan. (16 b). Typically smaller than carnearia, especially in the $, terminal joint of palpus 
much less extreme, particularly in the 2, the cell-mark of the hindwing normally a black dot, usually accom¬ 
panied anteriorly by a white dash on the 2 nd discocellular, occasionally also with a minute dot posteriorly. 
Point of origin of 2nd subcostal of forewing variable, probably oftenest from the cell, at least in the $2- Queens¬ 
land. the type series from Cedar Bay. St. Aignan produces quite similar forms, at least as to the 2 22 hitherto 
known; the one $ is large, rather bright (more recalling the tone of carnearia), the underside rather strongly 
marked, with particularly prominent cell-dots. From New Guinea also, at low elevation (Kumusi River) come 
a few specimens which I cannot yet definitely distinguish from olivescens. The mountain Organopoda of that 
county are very perplexing and unfortunately for the most part have occurred only in single specimens, often 
2- Two such (Upper Aroa River and Hydrographer Mountains), together with a 2 from Bomfia, Ceram and a 
very worn $ from Vulcan Island, would certainly have passed for olivescens except that the 3rd joint of the 
palpus is longer (and perhaps longer in the Hydrographer than in the Aroa 2U but must await better material. 
f. (?) subcarnearia nov. (15 f) combines the tone of olivescens with the markings of carnearia and may re¬ 
present yet another species. Angabunga River, 6000 feet or upwards, 1 2 ' n Mus. Tring. I find a similar 2 _a b. 
can occur among undoubted olivescens (Kuranda, 1 2) and that the Javan 2$ mentioned under acerbata show 
a similar variability. 
0. hadra sp. n. (16 b). 34 mm, with 2nd subcostal of forewing well stalked, 3rd joint of palpus moder¬ 
ately elongate; 2> 32 mm, 2nd subcostal from cell well before origin of 3rd, 3rd joint of palpus 2 3 length of 2nd 
joint, or rather more. Appreciably broader-winged than olivescens, the hindwing a little more produced to the 
anal angle, the forewing with termen fairly long but little oblique, both angles well expressed. Otherwise much 
like overgrown, weak-marked olivescens, but with the forewing, in the also the hindwing, strongly suffused 
with red beneath. New Ireland, November 1923— January 1924 (A. J. Eichhorn), only one pair obtained, 
both in the Tring Museum. - rubrior form, nov., possibly only an aberration but more probably a race or even 
- as the terminal joint of the palpus appears somewhat longer — a separate species, has the upperside redder 
(less strongly suffused with grey); 2nd subcostal of forewing connate with 3rd—5tli, but this may probably 
be individually variable. New Hanover, February—March 1932 (A. S. Meek), 1 2 in the Tring Museum. 
0. orbiculata Prout (16 b), described as a race of olivescens, is larger, the 3rd joint of the palpus relatively 
somewhat longer (almost as long as the 2nd), the cell-dot of the hindwing surrounded with whitish. Mt. Goliath. 
Central Dutch New Guinea, 2 2?. 
0. cnecosticta Prout (16 b). Palpus with terminal joint long, about equalling 2rd joint. Forewing with 
2nd subcostal from the cell in the $ type, but stalked in a 2 which is believed to belong to it. Distinct from 
all the preceding forms, except possibly annulifera, in the white cell-spot of the forewing, from annulifera in 
the structure of the palpus and in the conspicuous buff terminal spots on the veins. Underside fairly well marked. 
Kinabalu, at 5500 feet altitude. 
0. orbata Warr. (15 g). Size of orbiculata, much more reddish and much more clouded with black- 
grey. Distinguished among all the known Organopoda by the cell-marks, particularly that of the hindwing. 
The termen shows, on attentive examination, buff dots at the veins, but they are very small and much less 
conspicuous than those of cnecosticta. The ground-colour is more tinged with vinaceous than in that species 
and the 3rd joint of the palpus is not as long as the 2nd. The unique type is a J 1 from Biagi, Mambare River, 
British New Guinea. perorbata Prout, a $ from Mondoktoempang, W. Bali, 2500 feet, October 1934, 
recently sent by Mr. J. P. A. Kalis to the Tring Museum, may be provisionally accorded this status. 2nd sub¬ 
costal of forewing from the cell (in Warren’s type connate), apex of hindwing somewhat more rounded; fore¬ 
wing with costa blackish-mixed to beyond %, hindwing with cell-mark slightly larger.
