1889. ] INDIAN LEPIDOPTERA. 403 
Hab. Nilgiri Hills, northern slopes 3500 feet, June 1888. Two 
female specimens received from Mr. Hampson, and a pair from Mr. 
Lindsay. 
Distinguishable from the only other known species of this genus, 
M. ceylonica, by the pointed anal angle of the hind wings and by the 
uniform colouring of the front and hind wings in the female, whereas 
in the female of M. ceylonica the hind wings are entirely yellow. 
LITHOSIINE. 
Cossa RUMA, 0. Sp. 
Fore wings violet-brown, with a broad marginal band of paler 
colour, a suffused yellowish space at the base of the wing, extending 
to nearly the middle of the hinder margin and occupying more than 
the lower half, and a large pale yellow streak in the centre of the 
costa; the coloration of the fore wings varies somewhat in different 
specimens, the yellowish basal space being sometimes absorbed into 
the ground-colour of the wing, and in some specimens the yellow 
costal streak is reduced to a large spot. 
Hind wings pale greyish ochreous-yellow unmarked. 
Wings below of the same colour, but slightly darker; fore wings 
with the central space violet-brown. Front of head, palpi, body 
below, and legs ochreous; antennz and body above violet-brown ; 
abdomen palest, and in some specimens suffused with ochreous. 
Expanse of wings 13 inch. 
Hab. Mahableshwar (May 1887). Nilgiri Hills, 6700 feet (June 
1887). 
I have a number of examples taken by myself at Mahableshwar, 
and eight received from the Nilgiri Hills from Mr. Hampson. 
This is a larger insect than C. dasigera, the type of the genus, 
and is distinguishable from it by the fore wing having the inner pale 
area traversed by an outwardly oblique violet-brown fascia which 
extends from the base of the costa, whereas in C. basigera the pale 
basal area extends uninterrupted to the middle of the costa. 
ARCTID. 
PANGORA RUBELLIANA, 0. Sp. 
Allied to P. distorta, Moore. 
Fore wings dull slate-colour, markings pure white, a large crown- 
shaped patch running into the wing from the base, with two well- 
separated black spots in a line on its lower part, a large distorted 
central band, excavated on the costa, on the hinder margin of the 
wing and on both sides in its centre; a black spot above the outside 
central excavation, and a small black point above the excavation on 
the hinder margin; four large spots on the outer margin, one divided 
by the vein just below the apex; a smaller longitudinal spot just 
below and not touching the margin, another in the centre, also not 
ee the margin, and a much smaller spot on the margin just 
elow. 
Hind wings deep bright red, a bifid slate-coloured spot at the end
