edge. Posterior dorsal shield again bell-clapper- 
shaped, but reaching far more forward, reaching the level of 
trochanteres I, anteriorly sharp, gradually becoming wider 
backward. Anterior lateral shields wholly ventral. 
Middle lateral shields absent. Posterior lateral 
shields very narrow, a little convex outward and concave 
inward, posteriorly touching the widest part of the posterior 
dorsal shield; anteriorly reaching the level of trochanteres IV. 
Hairs: the same as in the protonympha, but behind the 
pair of minute hairs on the same level as the anterior point 
of the posterior shield there is a second pair of fine and short 
hairs. As to the copulation hole and tube see here 
below in the description of the female. 
Ventral side (Fig. 35). Epimera like in the proto- 
nympha. Shields like in the protonympha, except that the 
coxal plates IV are not represented inward of the epimera IV. 
The anal split is flanked by two unwrinkled parts, which 
may be considered as anal covers. Hairs: the posterior 
(proximal) end of the sternum is flanked by a pair of minute 
hairs; inside of the posterior parts of coxae III a pair of 
ditto; further backward, on a line with the anterior parts of 
coxae IV a pair of ditto; and on a line with the posterior 
parts of coxae IV a pair of ditto; finally on each anal cover 
one ditto, and the valves themselves flanked by a pair ofthin 
hairs, slightly longer than the valves themselves. Lateral hairs 
like in the protonympha. 
Mandibles large, seen with a dorsal view they project 
forward as a pair of cones. 
Maxillae normal. 
Legs normal; all the legs shorter than, or subequal to the 
greatest width of the body. 
Female (Fig. 36, 37). Length, measured on about 30 
individuals, from 640—-760 x. Colour light brown on the
