ANATOMY OF THE HONEY-BEE 193 



Closely associated with the reproductive organs 

 of the female is the sting; this is a barbed dart con- 

 nected with a poison gland, whose use is well known. 



In the abdomen of the male there is a pair of 

 organs, the testes, in which the spermatozoa are deve- 

 loped. These correspond in position to the ovaries 

 of the female, but are much smaller. From each 

 testis there extends a tube corresponding to the 

 oviduct, this is the vas deferens. The two vasa 

 defer entia unite and form the single ejaculator duct. 

 Each vas deferens is enlarged just before it joins 

 the ejaculatory duct, forming a reservoir for the 

 accumulation of spermatozoa; these reservoirs are 

 termed the seminal sacs. Appended to each seminal 

 sac there is a large glandular sac, which adds mucus 

 to the seminal fluid. Near the outer end of the 

 ejaculatory duct there is a pouchlike enlargement 

 into which the spermatozoa pass. Here they are 

 massed into a compact body, known as the sper- 

 matophore, which is transferred to the female at the 

 time of pairing. The terminal part of the repro- 

 ductive organs of the male, the intermittent organ, 

 has several appendages, which are firmly grasped 

 in the opening of the reproductive organs of the 

 female and are torn from the male when the two 

 pairing individuals separate. This causes the death 

 of the male. The male has no sting. (Plate XXVI,
