162 REporT OF THE DEPARTMENT OF BOTANY OF THE 
The ventral surface of the cephalo-thorax and abdomen bear 
characteristic short spines, placed regularly in pairs. These are in- 
dicated in Plate XIV, fig. 4. 
The legs are five-jointed and strongly haired, the longest hairs 
being always on segments 2, 4 and 5. The first pair of legs have 
each a single hooked claw; the claws on the other legs are paired 
and provided with a stalked suction gland. The epimera have a 
strong chitinous protection and meet along the median. 
Adult—(Male.) Body broadly egg-shaped; narrowing in the 
front while behind at the genitalia it is produced blunt and cone- 
shaped. Length about 160 microns, the greatest width 60-80 
microns. 
Rostrum very small, a round knot-like structure without mouth- 
parts. Cephalo-thorax similar to that of the female, but more 
broadly rounded. It bears four pairs of hairs, the first pair being 
very small and placed near the forward margin, the second ten 
microns long and the third twice as long as the second and nearer 
to the lateral margins. ‘These three pairs are situated behind each 
other in lines almost parallel with the lateral margins. The fourth 
pair are almost directly behind the third pair, 53 microns long and 
very stout. 
The cephalo-thorax and abdomen are separated by a transverse 
constriction. About 1624 microns behind this are a pair of stout 
hairs 33 microns long, situated near the lateral margin, while be- 
tween these and about 17 microns from the median are two shorter 
hairs. Just anterior to legs IV is a constriction behind which the 
body narrows cone-shaped to the genitalia. Legs I to TII are 
similar to those of the female. Legs IV are much thicker, in- 
curved, and each bears a terminal sickle-shaped claw. Short hairs 
are borne on each segment while on the last two are blunt spines. 
“he terminal segment has a single, long hair at the base of the 
claw. 
The ventral surface has characteristic, small spines the location 
of which is shown in Plate XIV, fig. 2. 
Gravid female-— The difference between the gravid and non- 
gravid female is in the enormous size of the abdomen. This swel- 
ling extends backward from the cephalo-thoracic constriction and 
does not include the thorax as in some other forms. When ex- 
tended, the abdomen may become 80 to 100 times as large as the 
unimpregnated female or even larger. During the extension of the
