THE LARVA AND NYMPH 



The Larva 



The larvae of mosquitoes, more especially of 

 Culex, are well-known objects. They can be seen 

 by holding up to the light almost any specimen 

 of water that has been left undisturbed for some 

 days, but especially water which contains mace- 

 rating leaves.
