Ventral side (Fig. 22). Epimera I thick, curve, 
joined to a sternum. Epimera II thin, as long as epimera I, 
more curve, especially in their proximal part, and directed more 
towards the median line than backward. The coxal plates II 
are limited posteriorly by a thin epimerite, curved backward, 
and touching most probably the ventral demarcation with their 
proximal end (like in the female). Epimera III and IV shorter 
than I and II, far backward, curved forward, especially in 
their proximal part; epimera III submarginal ; epimera IV sub- 
medial. Shields. I could not observe them, but most probably 
‘the coxal plates are distinct. Hairs. A pair of rather long and 
thin hairs aside of the posterior end of the sternum. A pair of 
shorter ones, marginal, outside of epimera III. A pair of longer 
ones inside of coxal plates III. A pair of shorter ones inside of 
coxal plates IV, aside of the anterior end of the genital aper- 
ture. Four pairs of short hairs on the anal valves and one pair of 
ditto aside of the anus. Genital aperture between legs IV. 
Penis, short, stylet shaped, its pointed end backward. Genital 
suckers distinct. Anus touching the posterior edge of the body. 
Mandibles (Fig. 24) short, stout, large; upper jaw 
triangular, with sharp triangular end-incisor, distinct canine 
and indistinct molar. Lower jaw very crooked, stout, with large 
base, with small end-incisor, small canine and backwardly 
directed low pointed molar. 
Maxillae (Fig. 22). Their coxae, trochanteres, femora, 
and genua fused together without any trace of junction. 
Inner malae almost parallelogrammical; lingua triangular; tibia 
nearly three times longer than tarsi; these are provided with 
a distal and external minute (olfactoric ?) rod and a distal 
and internal minute bullet shaped appendage. 
Pseudostigmatic hair (Fig. 23) in the armpit of 
legs I, a nodded wide and flat hair, with only about ten hair- 
like branches radiating from the distal half; the lengths of 
which increase distalward.
