convex ; abdomen tapering backwardly from legs III ; posterior 

 portion of abdomen with oblique sides ; posterior edge a little 

 excavate in the middle. — Textur e like in the larva. 



Dorsal side (Fig. 9). S h i e 1 d s. Anterior dorsal shield 

 extending from the front-edge to the prosomatic hairs, trapezoidal, 

 nearly twice longer than wide , wider posteriorly ; lateral edges 

 straight , posterior edge slightly convex. Behind trochanteres II 

 a pair of small Shoulder - shields. — Hairs. Vertical hairs 

 (Fig. 11) close together, very thin , reaching beyond the tips of 

 the mandibles. Prosomatic hairs behind the posterior corners 

 of the anterior shield ; the long ones slightly longer than the 

 shield ; the shorter ones minute. A little behind the shoulder- 

 shields a pair of short hairs. On a level with femora III a pair 

 of short hairs on equal distance from the median line and the 

 edge of the body. In the posterior angles of the abdomen a 

 pair of short hairs. On the posterior margin of the abdomen a 

 pair of still shorter hairs, and quite on the posterior edge three 

 pairs of hairs of which the outmost are the longest, longer than 

 the greatest width of the body ; then a pair of shorter ones, 

 slightly longer than half of this width ; finally inmost a pair of 

 very short hairs. 



Ventral side (Fig. 10). Epimeral wide apart ; exten- 

 ding forward to the head ; epimera II parallel to epimera I, 

 running forward to trochanteres I along the edge of the body ; 

 epimera III short, straight, slightly convergent forwardly ; epimera IV 

 short , proximally nodded inwardly. Shields. Oatward of 

 epimera III there is a small triangulär extracoxal plate, on which 

 the lateral hairs are planted. Hairs. Inward of the proximal 

 halfs of epimera II a pair of short hairs. Inward of epimera III and 

 a little distant from them a second pair of short hairs. On a line 

 with trochanteres IV near the median line a third pair of ditto. 

 A fourth pair of ditto flanks the anterior end of the anal split, 

 and a fifth pair is planted on the posterior margin of the abdomen. 

 On the two extra-coxal plates III the two lateral hairs are planted, 

 of which the longer ones exactly on the edge of the body, whilst 

 the smaller ones, extremely fine and short , a little more inward 

 and forward. Genital suckers. I found but one pair, 

 exactly before the pair of short hairs on the same level with 

 trochanteres IV. Anus touching the edge of the abdomen. 



Mandibles normal. 



Maxillae normal, with triangulär under-lip. (Fig. 10), 

 blunt outer malae , and two-jointed palpi , each Joint bearing a 

 ventral and a dorsal short hair. 



Legs (Fig. 9). The anterior legs already show the ventral
