and slightly broader than the femnr; the anterior outline is distinctly concave, 

 while the posterior is moderately convex. The hand, which is distinctly broader 

 than the tibia and much longer, is twice as long as broad and much shorter than 

 the finger; the convexity of the anterior side is much better marked than that of 

 the posterior; the immovable finger is provided with about 20 well separated 

 marginal teeth, which begin near to the base; the movable finger has in the lii'st 

 place about ten low and more or less indistinct „teeth" and in the distal half ten 

 others, like those of the immovable finger. 



Coxae (fig. 1 h). — At least the second pair of the coxae bears remarkable 

 hairs, arranged in an original manner (cf. p. 68) 



Legs (figs. 1 l-ni). — The hairs of the legs are long and jjointed; near the base 

 of the first tarsal joint of the fourth pair of legs an exceedingly long and slender 

 "tactile" hair is found (fig. 1 m); the arolium has a very long stalk, decreasing 

 towards the small sucking cup. The two first pair of legs are very delicate and 

 slender, compared with the much more powerful last pair. The Itasal part of the 

 first pair of femurs is almost twice as long as and much deeper than the tibial 

 part; the tibia is a trifle longer than the tibial femoral part, but distinctly shorter 

 than the undivided tarsus, which is again twice as long as the former and even 

 longer than the basal femoral part. The femur of the fourth pair of legs is very 

 powerful and about twice as long as deep; its trochantin is half as long as the 

 whole femur; the femur is twice as deep as the tibia, which is again a little 

 longer than the second tarsal joint, but much shorter than the two tarsal joints 

 combined; the first of these is scarcely half as long as the second. 



Colour. — The antennae and palps are pale yellowish brown, with fingers 

 darker; the céphalothorax is yellowish green with darker lateral margins. The 

 abdomen is more or less pale yellowish with darker greenish sclerites. 



Measurements. — Full grown specimen from Lem Ngob. Céphalothorax

J*. Abdomen (fig. 1 b). — The three first tergites, especially the second and 

 third, are shorter than the following; the three first bear apparently only two pair 

 of lateral hairs, the following three or four pair; the eleventh in addition to these 

 a pair of "tactile" hairs. The pale inconsj)icuous sclerites of the three first tergites 

 are almost as long as the tergite proper; those of the following are mucli shorter 

 than their tergites and the hairs are placed behind their posterior margins. The 

 last (VI— X) sternites are like the corresponding tergites divided into an anterior
