Ceylon. 



Q) The species was forwarded from Ceylon by Mr. E. E. Green, and the following; par- 

 ticul«rs are taken from the interesting notes he has furnished regarding it. The iusect is to 

 be found in its various stages of growth swarming within the clasping sheaths of the leaves 

 of the Indian corn plant {Zea mays). In wet weather it is accompanied by a sooty fungus 

 which has not been noticed at other times. It is also attended iiy ants. The eggs ri,re 

 bnried in the tissues of the plant on the inside of the sheathing leaves, the orifice being 

 concealed by a deposit of white woolly secretion. The effect upon the plants depends vipon 

 the period at which they are attacked. If attacked when young, they are stunted and 

 weakened. Older, well-established plants do not suffer so much.
