This account forms the first number of “Notes on Economic 
Entomology,” issued by the Indian Museum Authorities, and is so 
interesting that it is considered desirable to give extracts from it, 
especially as the wheat weevil causes very great injury to Indian 
wheat, both as regards quantity and quality, and is in many respects 
similar to the grain weevil, Calandra granaria, which does so much 
harm to wheat and other corn in British granaries. 
Mr. Cotes states, that in the latter part of June, grains may be seen
