Tl. "General Summary. As the result of the work of the author pre- 
viously S aici sien or now being communicated, the number of species re- 
corded f ta 
de India has been ie neeesohared augmented. Total number up 
o date rset y other observers is 30, those obser by the writer 
are 4], wo of which had been reported by pr us workers. Th

bution, as also due to a desire on the part of the writer not to base new 
species on minor structural differences. A more extended survey of 
these forms from different parts of India would be desirable.
