Nymplia. — Length 520 ,«. — Colour white, or pale. — Shapé 

 like that of nymphs of other species, but somewhat broader, 

 especially on the abdomen. — Dorsal side. (Fig. 5). The anterior 

 dorsal shield is nearly triaugular in shape, with its top forward 

 and with convex sides; it is scaly and provided with 4 rows of 

 little hairs ; the two marginal rows are of 4 hairs each, the two 

 inner rows of 7 hairs each; further indistinct pits (Erosions- 

 gruben Kolenati) are visible. The posterior dorsal shield is broad 

 pentagonal with its top forward and provided with 12 little 

 hairs; its breadth is about s / 3 of that of the anterior shield. 

 Tb ere are 4 distinct intermediate shields, nearer to the anterior 

 than to the posterior dorsal shield ; they are placed nearly in a 

 quadrangle; each of the foremost pair is as it were fused from 

 two smaller shields. Behind these distinct intermediate shields there 

 were 4 dull unwriukled spots visible, which I consider as rudimental 

 intermediate shields. The unprotected skin of the dorsum is provided 

 with little hairs, especially on the sides, where they form almost 

 two marginal rows. 



Ventral side. (Fig. 6). The sternal shield is small subheptagonal 

 with top backward, and provided with 6 hairs. The anal shield 

 is small, triangular, truucated anteriorly, cribrated posteriorly. 

 Around this shield there are many little hairs. Peritrema usual, 

 short, (Fig. 6.). 



Epistoma (Fig. 5 ) projecting far forward, reaching almost the 

 middle of the 3d joint of the maxillar palps, with almost parallel 

 sides and denticulated truncated top. 



Maxillar palps with apendage ventrally of the lst joint. (Fig. 

 6 and 7). Legs short, about as long as the width of the body. 

 On the outer side of coxae 1 and 2 a minute comb is visible, 

 both when the auimal is viewed dorsally and ventrally (Fig. 5 

 and 6). On the coxa 3 a similar comb is visible on the fore- and 

 hind side (Fig. 6 ). On coxa 2 there is a chitinous spine directed 

 forward (Fig. 6). 



Male. Length from 575 — 640 p. — Colour very pale;. with 

 a common pocket magnifying glass, however, the honey-coloured
