Descriptions of New Reterocera from India. 285 
Castniidae is the Neotropical and Australian regions. It 
is obviously a later development of the OastniidsSj having 
lost the many primitive characters found in that family, 
such as vein Ic of the fore wing and the closed cell of 
each wing with strongly developed nervules in it ; the 
proboscis also having become aborted ; the way the sub- 
costal veins of the forewing are emitted is also different 
in the two families.
