56 Elementary Zoology. 



The reprodttctive organs are elaborate. In the male the 

 testes lie imbedded in the fat body. From them arise two vasa 

 defereniia, which open into the wider and muscular ejaculatory 

 duct. At the junction of the two are the vcsiculcR semmales, 

 termed collectively the " mushroom-shaped gland." The 

 genital aperture, which is upon the last segment, just below 

 the anus, is provided with a complex series of chitinous out- 

 growths, the gonapophyses. 



In the female each ovary consists of eight tubes, which 

 unite to form the oviduct ; the two oviducts open together 

 upon the eighth sternum. Further back, upon the ninth 

 sternum, opens the spermatheca, which consists of a pear-shaped 

 pouch and a narrow coiled tube ; the latter seems to be the 

 equivalent of a second spermatheca. On the following seg- 

 ment open the much-branched colkterial glands. The female 

 is furnishedj as is the male, with gonapophyses.
