burfuce towards the convex isidc of the shell, and its ventral surface to- 

 wards the flattened side. The anterior end of the maggot lies very 

 close to the pointed end of the egg-shell where the micropyle ( PL 1]\ 

 ß(j. 7 VI ) opens, and its posterior hroader end lies in the rounded end 

 of the egg-shell. The anterior end is at times projected through the 

 opening of the micropyle, and it is possible that the maggot in this 

 manner takes the sticky envelope as a food. If we examine the tiny 

 maggot ( n. II, fi(j. 8 ) taken out of the egg-shell it will he seen that 

 each of its segments is provided at its posterior border with a single 

 transverse row of brown setiw 



On the anterior portion of the vagina ( I'l. II, p(j. 3 c) near the 

 junction of the two oviducts, are attached two kinds of appendages — 

 seminal receptacles and tubular appendages or cement glands. The 

 seminal receptacles [FL II, ßg. 3 d ; fig. 5) are three in all. Each of 

 them is a club-shaped blind tube, its free broader end which forms a 

 sort of sac, being oval in shape, and dark brown in color on account of 

 its chitinous nature (PL II, fig. Ö a). The entire surf ice of this oval 

 sac is marked with fine wrinkles. One end of this sac opens into a 

 long chitinous tube ( FL II, fig. ah) Avhich in its turn opens into the 

 anterior portion of the vagina. The sac together with the slender tube 

 is enveloped with a delicate cellular layer (FL II, fig. 5 c). 



The tubular glands or cement glands ( PL II, fig. 3 c) are two thin- 

 walled slender tubes placed a little further down the vagina than 

 the seminal receptacles. They are fibout 16 mm. in length, being 

 thickly marked on their surface with irregular wrinkles, and are en- 

 veloped with a thick layer of glandular cells each containing a large 

 nucleus. 



The posterior portion of the vagina is usually widened and very 

 extensible in nature. It is covered with numerous branches of trachea 

 which are given off from the spiracles opening on the 4th, 5th and Gth
