lothorax and trapezoidal abdornen. The line of demarcation between 

 cephalothorax and abdomen is distinct, and slightly curved back- 

 ward, situated alrnost one tbird of the whole length. Ventrally 

 (Fig. 20) I did not observe other particularities than those of 

 the younger stage, except that the chitinizations were slightly 

 stronger and more distinct. Length of larger, younger form about 

 240 M.; of smaller, final form about 224 M. 



Male (Fig. 21 — 29). Length from 400 to 480 M. — Colour 

 pale straw-coloured chitinous parts and legs slightly rosé ; generally 

 with black particles in the intestinal track. Shape elongate, conical 

 anteriorly, with excavations for the reception of legs 1 and 2 ; 

 widest just behind legs 2, then generally slightly constricted, 

 to become again wider-backward, but not so wide as behind 

 legs II ; finally rounded posteriosly. Yet exceptions are not rare, 

 so that the shape is in no case a good characteristic. So I have 

 drawn a specimen which has a beautiful oval form (Fig. 21). — 

 Texture finely punctured, except at the coxal plates. 



Dorsal side (Fig. 21). Twelve pairs of hairs are visible, arranged 

 in 6 transverse rows of 4 hairs each, most probably belonging to 

 6 segments. Of the first row of 4 hairs corresponding with legs I, the 

 inner pair is far forward and so close each other, that their basal 

 chitinous rings tough each other. This characteristic is not mentioned 

 by any former observer. The outer pair at a level with trochanteres II. 

 The second row, corresponding with legs II, is placed a little behind 

 the level of trochanteres II ; the inner pair slightly nearer the 

 median line than the edge of the body; the outer pair just behind 

 trochanteres II. The third row slightly curved forward, correspon- 

 ding to legs III, is situated in the middle of the body; the inner 

 pair just as far from the median line as the edge of the body; 

 the outer pair close to the margin. The fourth row, correspon- 

 ding to legs IV, slightly curved forward ; the inner pair nearer 

 the median line than the edge of the body; the outer pair close 

 to the edge, and just above legs IV. These 4 rows of hairs may 

 be called the smaller ones, whereas the two folloioing rows are 

 much larger. The Jifth row, curved forward, behind the legs IV,
