To take up the study of mosquitoes intelligently it is necessary to know a little of their position among insects. Entomologists in considering the subject divide from the nearly related Arthropoda, the Hexopoda true insects, and these are again divided into various orders, of which Hemiptera, Lepidoptera, Diptera, Coleoptera, etc., are perhaps the better known among the laity. Of these our present study takes us to the ORDER DIPTERA true flies. The members of this order have only two wings these are borne on the mesothorax. The metathorax is furnished with a pair of knobbed threads, the halteres. The mouth parts are formed for sucking. The metamorphosis is complete. The Diptera are divided into two suborders, Orthorrhapha and Cyclorrhapha, of which we have to do with the former. The Orthorrhapha are again divided into long horned Nematocera, and short horned Brachycera the Nematocera into True Nematocera, and anomalous Nematocera. Among the former, as aquatic nematocerous insects we find the mosquitoes, i. e. Family CULICIDAE.
