cl, division of amoebula to form enhsemospores ; e, liberated enhaemospores ; 
f, growth of enh8emosix)re into a crescent at expense of corpuscle ; g, male, and 
7i, female crescent ; i, male cell with projections, which lengthen, and are 
eventually set free as spermatozoa ; fertilisation of ovum by spermatozoon ; 
7i, fertilised egg as the active motile vermicule ; /, enlarged vermicule, after boring 
through the stomach wall of the mosquito, forming the sphere ; m, segment of 
sphere at maximum stage of development, containing countless needle-shaped
