Culex. DIPT ERA. 221 



The larvae of the Culices are very frequent 

 in {landing waters •, their bodies are compofed 

 of nine fegments, which diminifh in fize and 

 length from the head towards the extremity of 

 the body •, the laft of thefe fections is furnifhed 

 with a kind of ftigmate, through which the larva 

 breathes, frequently riling, for that purpofe, 

 to the top of the water. The head of the 

 chryfalis is fo much bent under the bread, that 

 the thorax appears to be the mod advanced 

 part of the body ; the ftigmates are placed upon 

 the back of the thorax \ the fegments of the 

 abdomen diminifh in fize towards its extremity, 

 the laft terminates in a kind of flat tail or fin, 

 by means of which the infect fwims or moves 

 itfelf in the water. 



The Culices generally frequent woods and 

 watry places ; they are known by the name of 

 Midges. 



Scopoli informs us, that where large quanti- 

 ties of them are found, the foil is generally 

 marlhy, and the air unwholfome. 



The females are very troublefome, and fling 

 fevereJy, which the males are feldom obferved 

 to do.
