changed to brownish, nearly always with a fleshy tinge. Occasional in several localities (S. India, Shan States 
and perhaps especially Formosa), the type <$ from Tainan, Formosa. aurata Wan., founded on a single $ aurata. 
from Kalao, is very likely a mere aberration of the following, but may well represent a separate local race, of 
a deeper “gilded yellow” and showing only, on the upperside, the cell-rings (larger on the hind wing) and traces 
of punctiform outer line (distal extremity of postmedian band, here nearer the termen the usual). The under¬ 
side (as often in the well-marked Indian forms) shows definite outer blotches (radial and posterior). incor- incorrupta. 
rupta Warr., provisionally regarded as a race, has the upperside “entirely devoid of darker atoms or suffusion, 
the ocelloid cell-spots distinct”, the forewing with traces of a dark postmedian line, which on the hindwing 
is marked with dark dots on the veins. Founded on a long series from Dili, Timor, “all exactly alike '. I have 
hitherto employed the name for all the variable forms which are spread over the Lesser Sunda Islands to Java, 
but it is only those from Sumba which seem at all constantly similar to the Dili series, those of some other is¬ 
lands including occasional throw-backs towards the Indian forms. Even at Dili (pace Warren) a few banded 
aberrations occur. 
14. Genus: Clsilothysmiis Him. 
(See Supp.-Vol. 4, p. 27.) 
Antenna of strongly bipectinate. Hindleg simple, in both sexes with all spurs. Forewing with apex 
acute, often produced, areole simple. Hindwing with the angles pronounced, a tooth or short tail at the 3rd 
radial; 1st median not stalked. On the early stages (of the genotype) see Vol. 4, p. 47. Range: Holarctic Region 
India to Formosa, Malaysia. 
C. comptaria Walk. (Supp.-Vol. 4, pi. 4 c). Formerty supposed to be a small Eastern form of the well- comptaria. 
known amata L. of Europe, this was proved to be quite distinct in the $ genitalia (see Supp.-Vol. 4, p. 27, 28). 
Generally duller-looking than amata , the irroration being stronger, the termen without rosy suffusion. Distri¬ 
buted in China, from Shanghai to Szechuan, besides occurring in the Ussuri district, Japan and I think Formosa. 
C. responsaria Moore (= strigulata Warr.) (16 f). Genitalia so similar to those of comptaria that one responsaria. 
is inclined to view it as the N. Indian representative there of. Very distinct, however, in the cinnamon ground¬ 
colour, above and beneath, which, indeed, distinguishes responsaria from all the other Calothysanis ; the oblique 
shade generally thicker than in most of the forms. Both the types were from the Khasis; the species occurs 
also in Bliotan and Tonkin. aganopis Prout, from S. India (the type from Malabar) is less warmly coloured, aganopis. 
pinkish buff rather than cinnamon, the oblique line pink, little darkened, the outer line inclined to break up 
into vein-dots, at least anteriorly. 
C. convectaria Walk. (16 f). Somewhat sharper winged than comptaria , the ground-colour more ochreous, convectaria. 
the costal margin of the forewing strongly darkened except towards apex. Silhet (type) and distributed from 
Sikkim to Szechuan, Tonkin and through Hainan and S. China to S. Japan, the Riukiu Islands and Formosa. 
baguionis subsp. nov. has a more fleshy tinge, the celldot of the forewing minute; the holotype and allotype baguionis. 
(especially the latter) rather small, the darkening of the costal edge perhaps less pronounced. Baguio, Benguet, 
Luzon, at 4000—5000 feet (A. E. Wileman), the typical pair from Trinidad, Baguio, at 4000 feet. 
C. nelsoni Prout (16 f). Superficially extremely similar to convectaria , sometimes scarcely distinguishable, nelsoni. 
On an average larger, of a deeper yellowish (without the fleshy tinge which generally appears in the brightest 
convectaria ); oblique line perhaps less perfectly straight; underside, especially of forewing, rather heavily irror- 
ated and suffused. Antennal pectinations perhaps slightly longer and more numerous. Genitalia remarkably 
different, as it is one of the few Calothysanis which have a well-developed bifid uncus; costa as long as valve, 
sacculus fused, etc. S. India and Ceylon, type from Madura district. 
C. oligoscia Prout (Supp.-Vol. 4, pi. 4 d) also belongs to the group with bifid uncus. Superficially it oligoscia. 
is perhaps best distinguished from comptaria by the somewhat smoother appearance of the wings, brought about 
by their less strong irroration, the slenderness of the oblique line and a slight proximal darkening of the costa 
(much less developed than in convectaria)-, costa, moreover, slightly more curved distally, angle of hindwing 
intermediate in strength between those of the two compared species; antemedian line obsolete. W. China to 
Upper Burma. — ab. pompalis Prout (Supp.-Vol. 4, pi. 4 c), a remarkable from Tse,-ku, is much more irrorated pompalis. 
and heavily marked, the antemedian line developed, but appears to agree in the genitalia with the type. 
C. correspondens Pimps. (16f). Easily distinguished by the much straighter postmedian line, especially correspon- 
of the hindwing; cell-dot of forewing generally strong. N. W. India to Tonkin, the type from Dharmsala. 
C. commixta Warr. (16 g) seems to be nearly related to nelsoni, but differs in its less yellow colour, its commixta. 
rosy fringes and rosy outer shade to the oblique line; hindwing, as in punctinervis (though on an average not
