Family 2. CULICID/E. MoSCJuiiOfS. StingilKJ GlldiS. The males neither sing nor sting, but dance ; and 

 their food is unknown. They are easil>- recognized by their feather-like feelers. The feelers of the females are 

 hairy though less feather-like. Their eggs are laid in a boat-shaped mass on the surface of stagnant water on 

 which it floats. In a few days these hatch and the larv;e wiggle out on the water side of the boat, grow rapidh , 

 and have a breatliing tube on the joint before the last of the tail. When full grown the\- change to pupa, and at 

 the same time they develop two breathing tubes on the chest part, and lose that of the tail. After a few da\s (he 



pupa hursts on the back, and the mosquito crawls out and ritles on the cast ofl' skin till its wings are hardened 

 enough to fly away. A mosquito's mouth is compo.sed of six pieces and a sheath: three fine needle-pointed hairs 

 form the underlip, two stronger ones with barbed points, the upperlip ; these five form a tube enclosing the 

 tongue. The mosq'iito diflers from the following families not only in the veins of the wing, but also by having a 

 long fringe on the hind edge, and scales on tlie veins.
