Mosquitoes are insects of peculiar interest on account of the relation 

 between Anopheles and malaria and ^des calopus and yellow fever. The 

 latter insect occurs only rarely in a few sea ports in California and the 

 disease is unknown here. Malaria however is wide spread in the central and 

 northern sections coincident with the distribution of the Anopheles. In the 

 San Francisco bay region two species of salt marsh mosquitoes, ^des quaylei 

 and squamiger are at times very annoying. Very successful control measures 

 have been employed. (See California Bulletin Number 178). The two most 

 common fresh water mosquitoes in the same region are Culex tarsalis and 

 Culiseta incidens.
