ground colour much darker, the discal purple line much more prominent, the 
purplish-grey border of the other form entirely absent, and the series of ocelli 
surrounded by a purple line. Every gradation is before me between the two 
extremes. Mr. Hamilton obtained a very long series of it in the spring, below 
Shillong in Silhet; the greater portion were, as they should have been, of the dry- 
season form, but a few were of the other extreme, and these he picked out, together 
with intergrade specimens between the two extremes, and sent them to me. The 
prevailing form of this species is therefore Khasicina in the dry season and true 
Malsarida in the wet season; and the occasional appearance of the one form or the 
other cut of its proper season will not upset the main fact of the occurrence of two 
distinct well-marked forms corresponding to the seasons, the dry and the wet, into 
which the Indian climate may be primarily divided. 5 ' 
Distribution. —The wet-season form has been taken in the Khasia Hills in 
August. The late Mr. W. S. Atkinson obtained it at Cherra Punji. Specimens 
from Sibsagar, in Assam, are in the Indian Museum, Calcutta. Mr. J. Wood-Mason 
(J. A. S. Bengal, 1887, 350) records “one male from Cachar, taken on JNTemotha 
Peak in September. 55 Mr. L. de Hiceville (J. A. S. Beng. 1888, 274) records “ the 
capture of numerous specimens by the Rev. W. A. Hamilton below Shillong in Silhet, 
remarking also, that it may be considered to be a rare species, as it appears to be 
strictly confined to Assam, though it is probably common enough in the spots 
where it is found at all. 55 An example from the Naga Hills is in the collection of 
Mr. P. Crowley. 
Of the illustrations of this species on our Plate 72, fig. 1, la, represent a male 
of the wet-season brood, and fig. lb, that of a male of the dry-season brood.
