hindwing distinguishes it from the nearest ally, M. mineus, Linn., the 
former having the posterior three only in line, the latter the posterior four. 
The species is widely distributed in India in the plains in suitable localities 
and is found almost throughout the year. The larvae are described by 
Davidson and Aitken, feeding on grasses and also on rice. Betham 
records the attraction mohwa refuse and jaggery have for these, as for 
other butterflies, in India ; the attraction presumably lies chiefly in the 
spirituous matter left in the refuse, just as the rum is the attraction in the 
entomologists “ sugaring ” mixture. We figure the curious pupa and 
imago of Orsotrioena meda, F., found on rice in the very moist areas of 
India.

Lethe euro fa , Fabr., is the large dark brown butterfly common in the 
plains of North India ; the upperside in the male has two white spots 
on the forewing, in the female has a broad white oblique band ; in both 
sexes there is a series of black ocelli on the lower surface of the wings 
towards the margin, with light lines on the inner and outer margins. The 
larva and pupa are described by Davidson and Aitken ; the former is 
green with a single short horn on the head and feeds on dwarf bamboo 
(Journ., Bombay N. H. Soc. V, p. 350). 
Ypihima contains one widespread species (Y. hubneri, Kby.) out of the 
22 known as Indian, as well as two which occur in the plains, /. baldus, 
Fabr., and Y. inica , Hew. They are smaller dusky butterflies with
