4.SUBFAM. CULlCINyE, Theobald 



This in the largest subfamily and contains a number of diverse genera. They can easily be seen 

 to belong to this group, by the short 9 palpi and long (f palpi. They most nearly approach the 

 Toxorhynchitinae in this respect, but the longer first submarginal cell at once separates them. 



Characters. — Head clothed with all flat scales (Stegomyia) or a mixture of flat, narrow-curved 

 and upright forked ones. Palpi long in the (f , either clavate (Theobaldia, etc) or acuminate (Culex, etc); 

 in the 9 short and composed of 3 to 5 segments. Proboscis straight and moderately thick. Wings with 

 moderately long fork-cells, the first submarginal as long or longer than the second posterior cell in the 9 ; 

 scales of various forms in the different genera. Ungues of the 9 's equal, simple or uniserrated ; of the tf's 

 the fore are unequal, simple uni-or biserrated. The chief distinguishing characters are (1) the palpi 

 and (2) the venation. 



The subfamily contains 3o genera.
