In medical entomology the Culicidae are in a dominant position because the carriers of the most frequent and feared tropical diseases (malaria, yellow fever, etc.) belong to this group. In accordance with this importance, ever since the discovery of the part they-play as carriers, their systematics and biology have been to an increasing degree the object of scientific research, so that today one can say that they are the best known family within the order Diptera. The systematics of this family has reached a certain peak and completion through the summarizing works of Martini (1931) and Edwards (1932). However, the complete speciation is not fully understood even up to this day. New species are still being described, especially from South America and the Pacific territory. The knowledge of the biology of the different species is still full of loop-holes in spite of many known details. It has been best worked out for some of the Anopheles species. Here we feel the limiting influence of applied science which pays attention to the" important" species (the carriers) but frequently ignores the" unimportant" harmless species. In con-nection with the questions of distribution, breeding habits and susceptibility for certain parasites and the problems of combating them, the Culicidae have been used for physiological experiments, but our knowledge even in this field is very incomplete.
