4. Genus: Organopoda 
Characters nearly as indicated under Discoglypha. Apart from the elongate palpus (particularly as 
regards its more or less long, exposed 3rd joint), which holds for all except the intermediate species brevipalpis 
and atrisparsaria, it is distinguished chiefly by the much more extreme specialization of the <$ hindleg (see 
Hampson, Fauna of British India, Moths, Vol. 3, jn 451), the variable point of origin of the 2nd subcostal of 
the forewing (as in Rhodostrophia) and the small, pointed aedoeagus (that of Discoglypha, so far as tested, is 
strong, pistillate and furnished with cornuti). A genus of not many species, but probably of greater antiquity 
than Discoglypha, having a very wide distribution in the Indo-Australian Region. Genotype: 0. carnearia Walk. 
0. fulvistriga Bastelb. (15 f). J unknown. The unique $ is worn and the structure not indicated; per- fulvistriga. 
haps a Discoglypha akin to hampsoni (15 e) but duller, the median shade more dentate, on the hindwing more 
distally placed than in most hampsoni. Warren (MS) perceived a “pale spot at each end’’ of the cell-mark, 
as in D. hampsoni or some 0. olivescens. Arizan, Formosa.

nation of the 2nd subcostal of the forewing from the cell; but transitional in that the palpus is not elongate, 
its terminal joint scarcely, if at all, longer than in Discoglypha. Closely similar to carnearia (16 a) but the fore¬ 
wing has the apex slightly more acute and the cell-spot slightly enlarged, nearly always with minute white 
pupil. Kachin Hills, Upper Burma. 
0. atrisparsaria Wehrli (- brunnearia Oberth., nec Leech ) (Supp.-Vol. 4, pi. 4 b) is very near brevipalpis, atrisparsa- 
but superficially very distinct in the heavy black median shade, etc. On p. 26 of the volume indicated, I referred 
it to Discoglypha, but it certainly cannot be separated generically from brevipalpis , though the point of origin 
of the 2nd subcostal of the forewing generally differs somewhat, being usually connate with 3rd subcostal; the 
genitalia are so similar as to suggest that they are races of a single species. I therefore now accept Wehrli 's 
original taxonomy. Distributed in China, the type from E. China (perhaps Shanghai, the first locality mentioned). 
0. annulifera Bull. A true Organopoda. with long terminal joint of the palpus. Easily distinguished by annulifera. 
its pale-pupilled cell-spot on the forewing, strong black dots on the outer line and sharply black terminal dots. 
The type — unfortunately the only specimen yet known from N. W. India (Dharmsala) — is a little smoother- 
looking (less irrorated) than the following form, the cell-spot, of the hindwing scarcely larger than in brevipalpis , 
and most probably represents a separate race. - - signifera subsp. nov. (16 a). Slightly more reddish than the signifera. 
type, the markings (except perhaps the cell-ring of the forewing) coarser, the cell-spot of the hindwing much 
enlarged. Not rare in the Khasis; type in the Tring Museum. The only Ceylon specimen known to me, a J from 
Haputale, closely agrees with the Khasi form. 
0. carnearia Walk. (16 a). Dnller and darker (especially in the typical Ceylon race) than annulifera, the carnearia. 
cell-marks smaller, that of the forewing not pnpilled, the other markings weaker, the terminal dots wanting; 
terminal joint of palpus still longer. — himalai'ca subsp. nov. Somewhat brighter (a little more reddish and himalawa . 
suffused with grey than annulifera), cell-spot of hindwing generally larger, its pupil less pure white; underside 
with paler hindwing and often a conspicuous pale admixture in distal area of forewing. Khasis (common) and 
Sikkim (less common), the Khasi holotype in the Tring Museum. A few examples from scattered localities 
(Hainan, the Riu-Kiu Islands, Formosa, Sumatra, the Mentawi Islands, W. Java, Kinabalu) which seem to 
belong here suggest greater variability, with the probability of a number of separable races. 
0. acmaea sp. n. (16 a). Rather smaller than average carnearia (length of a forewing 14 mm. or barely); acmaea. 
3rd joint of palpus considerably less long than 2nd (in carnearia about equal); 2nd subcostal of forewing arising 
from cell (in carnearia generally well stalked); coloration brighter, more inclining to orange, costal region of 
forewing shaded with grey, especially in proximal part; cell-spots intenser, that of the forewing a little larger; 
underside more suffused with reddish. Mountains of Malaya, the type from Bukit Kutu, Selangor. 3300 feet, 
a second $ from Fraser's Hill, Pahang, 4200 feet; discovered by Mr. H. M. Pendlebfry. Type in the British 
Museum. 
0. subbrunnea Warr. (16 a). Smaller and paler than carnearia , the cell-spot- of the hindwing reduced, subbrunnea. 
long-oval, with a white dot in its anterior part. We figured a larger, fresher d from Sambawa, but a series since 
received from W. Celebes shows it to vary in size and tone. Closely like olivescens. palpus longer. 
0. acerbata sp. n. (16 a), a collected on Fraser’s Hill with acmaea (H. M. Pendlebury), but very acerbata. 
distinct therefrom, has the 3rd joint of the palpus as long as in carnearia, the tone of a rather dull olivescens 
(16 b), the costal region of the forewing not notably suffused with grey; distal areole very small (2nd subcostal
