 in the larvae of Culicidse, situated either round the 

 fin-like processes of the abdominal segments,

 it inosculates in the torulus, often subglobose,

Bursa copulatrix. — An evagination of the vagina, 

 into which tlie penis of the male is inserted in 

 copulation. (In the Lepidoptera the bursa 

 copulatrix is peculiar, in that it is not a simple 

 evagination of the vagina, but a tube, open at 

 both ends, one end leading into the vagina, 

 the other into the surface of the body ; so that 

 here the female genital organs have two pores, 

 that into the bursa serving for copulation, 

 whilst the vaginal opening proper allows only of 

 the escape of the eggs.) (L. hursa, a purse, and 

 from copiilare, to join.)
