CULICIDA: (Gnats or Mosquitoes). 
The discovery of the dissemination of malaria and other diseases through 
the agency of mosquitoes has led to an increased study of the taxonomy, . 
anatomy, and bionomics of our native species. 
The following is probably the most useful paper for purposes of identifica- 
tion :— .

mologist, xlv. pp. 191-195, 217-220, 260-264 (1912).

dealing with the species of the whole world. Such are—
