Genus V. Culex. 

 Linn. Syft. Nat. page iooi. 



The mouth of the Culex is formed by a 

 flexible (heath, enclofing fetae, or briftles, 

 pointed like flings. 



According to Scopoli, the bridles of the rof- 

 trum in this genus are four in number, and two 

 of them are longer than the others ; the fheath 

 is long and porrecled, and the palpi are incum- 

 bent upon the bafe of the roftrum. 



The antennae of the female Culices are fili- 

 form, thofe of the males feathered. The thorax, 

 in both fexes, is gibbous, and the abdomen atte- 

 nuated, growing fmaller from its bafe to its ex- 

 tremity; this part, in the females, is generally 

 longer than the wings; in the male, on the 

 contrary, it is much fhorter : the wings, in 

 both fexes, are extended horizontally along 

 the abdomen. The Culices have no ftem- 

 mata ; they very much refemble the fmaller 

 Tipula^, from which, however, as GeofTroy ob- 

 ferves, they may be eafily diftinguifhed by their 

 mouth, which, on comparing the characters 

 given to the two genera, or the infects them- 

 fclves, will appear to be formed very diffe- 

 rently.
