 and pale orange. The dorsolateral expansions of the venti-al and 

 dorsal abdominal plates are but slightly indicated in (lie last

The testes of the maie arc entireîy separated from cach olher, 

 and lie one on each side of the abdomen, with the ctils of the

 globose. 



The female bas 8 tnbes in each ovary (OV. fig. 11). The nrinary 

 tnbes (UT) arc 4 in number, bulbous at their bases, where they open

 rior portion including the vagina and génital orifice. Though I 

 bave termed it bursa copulatrix, it perhaps functions also as a 

 réservoir for eggs at the time of ovipositing. Opening dorsally into 

 the posterior part of the bursa (or vagina) are two large, tubular 

 colleterial glands (CG), uniting in, a common duct at their ba es. 

 Thèse glands lie one on each side along the abdomen, and at the 

 time of egg-laying are pale yellowish.
