THE FEMALE GENERATIVE OBGANS. 107 



which I strongly suspect it does, this is only represented by its four lateral 

 appendages. 



The intromittent organ is l-30th of an inch in length, which corresponds 

 with the distance between the external opening and the neck of the bursa 

 in the female. 



The relations of the crest and palpus -like appendages during the sexual 

 act, are, probably, as follows : The crest is brought into relation with the 

 interior of the last joint of the ovipositor, distending the extremity of the 

 oviduct, whilst the palpus-like organs are in relation with its lateral 

 surfaces externally. 



The palpus-like organs are apparently sensory. They are hollow, 

 slightly curved, and terminated by thin rounded spoon-shaped blades 

 the concave or posterior border is furnished with a single row of stiff hairs. 

 The base presents a welUmarked articular surface formed of two parts at 

 right angles with each other. 



Section XXI. The Female Generative Organs. 

 PLATE X., Fios. 17. 



The female generative organs (Plate X., fig. 1) consist of 

 the ovaries and their ducts, the common oviduct, the bursa, the 

 seminal receptacles, the albumen glands, and the ovipositor. The 

 ovaries are circular discoid masses of ova, situated at the sides of 

 the abdomen, and largely supplied with tracheal vessels from the 

 second abdominal spiracles. They consist of numerous follicles 

 which terminate the oviducts, each follicle containing a series 

 of ova, one behind the other, in various stages of development. 

 The follicles are so arranged that the ova are packed side by 

 side with their long diameters vertical to the surfaces of the 

 disc of the ovary. The oviduct commences upon the inner surface 

 of the disc by the union of the follicles, and the outer surface
