In addition to the three complete rings there are one or two small patches of

This completes our study of the adult insects, and we must now learn
about the eggs, larv and pup.
The eggs of
Anopheline
mosquitoes.
(1) The eggs of Anopheline mosquitoes are laid separately, and when
deposited on water they quickly separate from one another and float as
isolated eggs scattered irregularly on the surface of the water. They are tiny
rod-shaped bodies which cannot be seen plainly except with the aid of a
magnifying glass. If one of them is taken up in a spoon or on the edge of
a piece of blotting paper and transferred to a drop of water on a glass slide
