of hairs (one pair more than in the protonympha). — Stigma 

 dorsal, outside of the most posterior dorsal hair, on the level 

 between legs 3 and 4. — Periirema wholly dorsal, diverging 

 till the level between legs 2 and 3 , and then converging to 

 the level of legs 1 and 2 — Ventral face (Fig. 23) like that 

 of the protonympha , but with a pair of hairs between the sternal 

 shield and coxae 3, and with 11 pairs of hairs l)etween coxae

 Dorsal side protected by two dorsal shields , which are coalesced as 

 to form one. Together they form an elongate hexagonal shield, 

 blunt, with two sides forward, pointed backward. Six pairs of hairs, 

 of which the two foremost pairs are planted iii the margin of the shield. 

 Stigma and peritrema like in tlie deutonympha. — Ventral side 

 (fig. 25). Sternal shield shield-shaped with a prominent anterior 

 top and two anterior rounded corners , and with 5 pairs of hairs. 

 Under the anterior top the genital opening. Between the sternal 

 and anal shields 2 pairs of hairs. Anal shield with 4 pairs of hairs and 

 flanked by two pairs — Legs (Fig. 24) short , thick . almost regularly 

 with 6 rows of hairs, two rows of minute hairs ventrally, 2 rows 

 on the sides, and 2 rows dorsally. The dorsal hairs of femur and

 Shape very singular: the fore-half Spinturiiix-Wke , the hinder-half
