to allow for its expansion during the passage o£ an egg. Another series o£ 
muscles (m*) are found, arising from tlie lateral walls of the spcrmatheca and 
terminating ar-ound the common oviduct at a short distance from its base. 
The common oviduct enters the " ovipositor " between the hi' muscles. 
When the ovipositor is in repose — as depicted in PL 32,- — it consists of 
two sheaths, the outer or basal portion (ots), which is a transparent tube 
lightly chitinized, and the inner sheath or distal portion (ins), which is a con- 
tinuation of the outer sheath. The two portions join at the point where the 
common oviduct enters. The surface of the distal portion of the " ovipositor "

is covered with recumbent brown chitinized setse, which extend as far as the 
bursa copulatrix {be, text-fig. 3). The apex of the "ovipositor" (text-fig. 3) 
is stoutly chitinized, and consists of paired rounded basal pieces (fip), between 
which is the vaginal orifice {vo). Arising from each of the basal pieces is a
