The accessory glands (A.G. Fig. 14) we a pair of 
white almost round organs, separated from each other in the 
mid-ventral line by a small space through which the enero 
duct passes. These glands are in contact with the ejaculatory 
duct for adistanceof 3mm. When rendered transparent each 
gland presents a honeycomb appearance, the wall of the comb 
appearing darker than the rest. In sections large cells are 
visible with distinct nuclei and granular cytoplasm. Nothing 
is known at present regarding the function of these glands. 
The testis on each side opens into the corresponding vas 
deferens (V.D.) which is white and swollen at its origin where 
it partly covers the base of the testis, and runs as a narrow 
tube along the front border of the accessory gland towards the 
median line of the body. Subsequently the vas deferens 
curves at a right angle and after passing backwards for about 
a millimetre, the ducts of the two sides meet and continue as 
the single ejaculatory duct along the mid-ventral line between 
the accessory glands where the duct is thick walled with a red 
streak. Beyond the accessory glands, the duct narrows again, 
traverses segments VI and V II and enters the base of the penis 
in segment [X. 
The oedeagus or penis (OE. Fig. 14) is a globular brown- 
ish powerful organ lying below the rectum. Its walls are 
strengthened by chitinous pieces, as described in connection 
with the external genitalia. Two of these pieces project be- 
yond the opening of the penis and are curved at their ends, 
which with two others, the ‘ laterals’ (L), are probably used for 
dilating the vagina. 
Female Organs (Fig. 15): consist of ovaries, oviducts and 
accessory glands. 
The ovaries (Fig. 15, OV.) are white flat masses lying below 
the alimentary canal, one on each side. Their size depends on 
the stage of ripening of the eggs. When the latter are fully 
developed, they fill up the whole abdominal cavity, sometimes 
extending into the thorax as well. Each ovary — of 
seven tubules (Fig. 15 OV. TB.), not eight, as is usual among 
the Orthoptera (cf. Cockroach, Miall and Denny); thetubules are 
held together by fat tissue and tracheae so as to form a flat 
plate. Each tubule is about 4 mm. long and presents a beaded 
appearance owing to the contained eggs which distend its 
elastic wall. It tapers in front, then suddenly narrows con- 
siderably (terminal chamber) and unites with the extremities 
of other tubes to form a slender, solid filament, which passes 
body. High up in the tubule, the narrow lumen is occupied by 
clear protoplasm. Further below, where it is wide, large round- 
ed masses of protoplasm appear, which gradually take up the 
form of eggs. These arrange themselves in a single row of 12 
13 and give the characteristic beaded appearance. The
