the smaller ones are very short and fine and are planted more 

 inward and forward. 



Mandibles normal. 



Maxi 11 ae normal, with a pair of coxal hairs (Fig. 13), 

 a triangulär under-lip, blunt outer malae, and two jointed palpi, 

 of which each Joint bears a dorsal and a ventral hair. 



Legs (Fig. 12). The ventral triangulär outgrows of genu 

 and tibia I and II are still more developed than in the proto- 

 nympha. The tarsi I and II are sligthly S - shaped. Legs I: 

 genu dorsally with proximal thorn and distal hair, ventrally with 

 middle long fine hair ; tibia with distal tactile hair ; tarsus dorsally 

 with curve olfactoric hair in the middle of the proximal half, 

 one ditto distally and a very short distal hair ; laterally with 

 two distal fine and short hairs ; ventrally with a short and fine 

 hair in the middle of the proximal half. L e g s II : femur ventrally 

 with a long fine hair in the middle ; genu dorsally with a proximal 

 thorn and a distal very short hair ; tibia with a distal tactile 

 hair ; tarsus like tarsus I. L e g s III : genu and tibia each with 

 a distal tactile hair ; tarsus with 3 inner short and fine hairs, 

 one outer and distal ditto and one dorsal and distal ditto. 

 Legs IV : tibia dorsally and distally with a tactile hair ; tarsus 

 like tarsus III. Praetarsi long , wide , curve ventralward ; 

 ambulacral suckers small. 



Female (Fig. 14—15). Length 264—320 /<. — Colour 

 slightly darker than the dentonympha. Shape elongate, nearly 

 twice longer than the greatest width ; with triangulär portion 

 between the anterior legs ; widest before legs III ; from this point 

 slightly becoming narrower forwardly, sooner becoming narrower 

 backwardly, posteriorly almost rounded. Texture of the shields 

 smooth and finely porate, of the weak skin fine wrinkled. 



Dorsal s i d e (Fig. 14). Shields. Anterior dorsal shield 

 trapezoidal, twice longer than its greatest width ; widest posteriorly, 

 where it is twice wider than anteriorly ; lateral edges straight, 

 only slightly concave posteriorly ; posterior edge slightly convex. 

 Shoulder-shields triangulär, with rounded inner posterior angle. — 

 Hairs. Vertical hairs close together , fine, extending slightly 

 beyond the tips of the mandibles. Long prosomatic hairs longer 

 than the greatest width of the body, proximally thick, gradually 

 becoming extremely fine towards the free end, planted in the 

 posterior corners of the anterior shield. Short prosomatic hairs 

 minute, inside of the long ones. Close behind the shoulder-shields 

 a pair of stiff bristles , sharply pointed and as long as the half 

 of the width of the body. On a line before the trochanteres III 

 a pair of ditto , between the edge of the body and the median
