Notes on the Commoner Species 139 



ally spotted wings, and the long black legs of Anophe- 

 les enable any one to distinguish them at a glance. 



Many specimens die during hibernation, especially 

 if the temperature fluctuates frequently. 



The three malaria-carrying species of Anopheles 

 are prolific breeders and greedy feeders, often void- 

 ing blood while sucking. Nevertheless, blood is not 

 necessary for either mating or laying. A male and 

 a female crucians, reared from larvae collected by 

 Dr. Dupree, were placed, on emergence April 21st, 

 in a large cage with dried figs and a shallow saucer 

 of water. On the 28th there were a number of 

 eggs, but there is no record of their hatching. 



Crucians is not recorded as depositing more than 

 one batch, but pnnctipennis and maculipcnnis will 

 ovulate several times. The following is the record 

 of a specimen of A. pnnctipennis, which was kept for 

 19 days in the laboratory:
