MEDICAL ENTOMOLOGY 



INDIAN SPECIES OF ANOPHELES 



The Indian species of Anopheles have been more thoroughly studied 

 than those of any other country, and in James and Listen's Monograph, 

 the second edition of which has recently appeared, the worker will find 

 an accurate guide to the identification of the known species. Stephens 

 and Christopher's pioneer work on the larvae of the Indian species is 

 also worthy of note. The descriptions which follow are, in the main, 

 taken from the works of the above authors. Many of the papers 

 published in Paludism have also been consulted. The synoptic table 

 prepared by Major Christophers, I. M.S., which is issued by the Central 

 Malarial Bureau, Kasauli, will be found most useful, and is the easiest 

 one to work with.
