AN EXHIBIT COLLECTION OF ECONOMIC 

 INSECTS IN THE INDIAN MUSEUM. 



By EDWARD BARLOW. 



The collection here noticed has been prepared for exhibition in 

 the Indian Museum, with a view to illustrate the life histories of 

 some of the more important "economic" insects, both injurious and 

 useful, in the various stages of their development. It refers solely 

 to Indian species, and is as complete as it has been possible to make 

 it from the materials, and within the limits of space available, in the 

 Museum, 



The insect pests are arranged not in any natural order, but in 

 accordance with the plants which they attack : thus the insects that 

 attack tea and coffee are placed together, then those that attack 

 cereals, and so on. 



Wherever necessary, the actual exhibits have been supplemented 

 by enlarged illustrative drawings. 



The collection is exhibited temporarily in a series of cases run- 

 ning the whole length of the southern side of the Bird Gallery. 



The following is a list of the exhibits : — 



I. — Insects and mites that attack tea and coffee plants. 



1. Andraca bipunctata, V^\k.=.trilochoideSy Moore (Bombycid 

 moth).— Reported as defoliating tea bushes both in Cachar and in
