MALE RE 
Male. (Fig. 40, 41). Length 590 4. Colour brown. 
Shape long-oval. Texture: posterior dorsal shield trans- 
versely »moirée« ; all the other hard parts smooth (with 
numerous pores, of course); soft parts finely wrinkled. 
Dorsal side (Fig. 40) nearly wholly protected by two 
shields. The prosoma was shoved in the metasoma, partially ; 
so I could not discern accurately the posterior limits of the 
anterior shield nor the anterior ones of the posterior shield, 
but I think I have well interpreted the facts and represented 
them rightly in my figure 40 by means of a — — — line. 
Anterior dorsal shield for the greater part better 
chitinized than its posterior part; the demarcation between 
these two parts is represented by a dotted line running from 
the trochanteres II first backward, then inward. Between the 
two long prosomatic hairs a light, less chitinized line runs 
over the smaller hairs; this I have represented again by a 
dotted line. Anteriorly two longitudinal chitinous ridges, some- 
what diverging backward. Hairs. A pair of thick vertical 
hairs, extending scarcely before the mandibles. The pair of 
prosomatic hairs is long; they extend to trochanteres IV. The 
pair of hairs inward of these long ones is much shorter, it 
does not even reach the posterior edge of the shield. On the
