GEROSIS; COLADENIA. By Dr. A. Seitz. 
corona. S. corona Smpr. (163 1). The spots on the forewing are quite similar as in dirae, but the band of the 
hindwing has become a large pale ochreous oval, and the under surface exhibits numerous distinct light grey 
radiary patches before the margin. From the Philippines. 
fumosa. S. fumosa Elw. (163 f). Here the hindwing above is quite brown without a white band; beneath 
the latter is almost as in dirae, but above all the spots on the forewing are smaller. Borneo. 
diversa. S. diversa Leech (Vol. I, pi. 84 e) which has been dealt with in Vol. I, p. 334, occurs also in the 
Indo-Australian Region, in the Khasia Hills in Assam. Specimens from there have the same colouring as the 
palearctic specimens figured in Vol. I, but they seem to me to be smaller on an average. 
narada. S. narada Mr. (163 f) is a common insect from the Himalaya, also known from Pegu. The cellular 
spot in the forewing crosses the whole cell-end and together with the square spots below it it forms a white 
discal band which increases in width towards the hindwing and passes over directly into the very broad band 
of the hindwing. Below the cell of the hindwing there is a thick black dot. 
bhagava. S. bhagava Mr. hardly differs above and not at all beneath from its form andamanica Wood-Mas. & Nic. 
andamani- (103 f); it is not lying before me. It is reported from Burmah and is probably allied to phisara Mr. (163 f) from 
yhi sard. Sikkhim. The latter form, however, does not only exhibit much more white in the disc of the forewing, but 
the whole hindwing is white excepting the base and marginal band, and the abdomen is above also white (except 
the base). 
moorei. S. moorei Mab. (Vol. I, pi. 84 e), described from palearctic China, and having been dealt with Vol. I, 
p. 334, with the form sinica Fldr. (— felderi Btlr.) from Central China, also occurs in the Indo-Australian Region, 
in Formosa. 
S. tethys Men. (Vol. I, pi. 84 f) is in typical specimens palearctic (Japanese), but it also occurs in 
formosana. Formosa in much darker specimens: - formosana Fruhst. nee Matsumura. 
milliana. S. milliana Swh. has remained unknown to me. 
12. Genus: GJerosis Mab. 
The genus is founded upon a very much damaged specimen. On the fore wing vein 5 rises close at the 
upper cell-angle; palpi porrect, posterior tibiae with 2 pair of spurs. 
hamiUonii. G. hamiltonii Nic. (168 c). Forewing above olive greenish-brown with 2 very irregular broad black 
discal bands being contiguous in the centre; 3 minute subapical sjiots; a similar very small spot in the 2nd 
median area; a very narrow one through the centre of the 1 st median area; before the margin an indistinct 
broad blackish band. Hindwing similarly coloured, distally strewn with greyish; from the costa near the apex 
a curved band of black spots extends to the 2 nd median branch; at the cell-end a light line. Under surface 
wine-coloured brown, disc of hindwing strewn with whitish, macular band as above. — The specimen originates 
from Sylhet and may be aberrative, in any case it has never been found again. 
13. Genus: Coladcnia Mr. 
The genus comprises about l dozen species and has been briefly characterized in Vol. I, p. 334. Only 
of one species the larva is known, being green with a black head which is indented on the frons, though not so 
deeply as in the larvae of the Tagiades. Pupa of the usual shape, without a distinct apex of the head or a 
prolonged case of the proboscis. The imagines are yielded in the hot districts already after a week or two; they 
fly in the sunshine, but are fond of resting on the underside of leaves with their wings spread out. 
indrani. C. indrani Mr. (163 f). This beautiful lepidopteron is distinguished by its bright colours, the ruddle- 
red surface of the wings exhibiting conspicuous white hyaline spots and black punctiform markings. The 
marking itself is similar to that in the common dan. From Sikkim through India to the Nilghiris. In typical 
iissa. specimens the 3 small subapical hyaline spots are situate in an oblique row. — In tissa Mr. (= laukae Plotz), 
vposaiha. from Ceylon, the most central hyaline spot is removed towards the base. — uposatha Fruhst. are lighter yellow 
specimens from Upper Burmah, whilst specimens from Tenasserim are said to resemble again the type. The 
imagines seem to occur rarely everywhere. 
dea. C. dan. This species has already been dealt with in Vol. I, p. 334, and figured in its palearctic (larger) 
fatih. form dea Leech from West China (pi. 84 f). — fatih Roll. (163 f) is the form distributed from North West India 
to the Panjab. Likewise larger and also paler than typical dan. — In India, as far as its north-western part, 
dan. typical dan F. occurs, distinguished from the very similar Javanese form eacus Latr. (= dichroa Plotz) (163 g) 
cacus. occurring besides in Bali by a softer brown colour and larger discal hyaline spots on the forewing. —
