Pedipalpi, Ricinulei, and Opiliones. 41 



on second pair. Femora of first pair (fig. 4 c) conspicuously 

 curved upwards with the lower margin rather concave excepting 

 towards the base, of second pair feebly curved, while the two 

 other pairs are straight (fig. i e). Tibiae somewhat longer and 

 deeper than the patellae, in the anterior pairs about half as long 

 again as deep, in fourth pair proportionately a little longer. 

 Tarsi of first pair (fig. 4 c) slightly less deep than the tibiae, 

 and the "solea" occupies little less than half of the lower mar- 

 gin of the tarsus. 



The upper side of the body with numerous extremely short, 

 thick, fusiform or rather clavate hairs which increase a little 

 in number posteriorly, so that they are closer on the posterior 

 abdominal tergites than on the cephalothorax ; the ventral 

 surface has a number of normal hairs which are longer and thicker 

 on the coxae than on the abdomen, where they are short 

 and very thin. The legs, excepting their tarsi, have a number 

 of very short, fusiform hairs on the upper surface and normal 

 hairs on the lower side of the joints, while the tarsi have only 

 normal hairs which on the lower side are longer than on the other 

 joints excepting of course the solea of first pair which is 

 densely clothed with very short and thin hairs. The palps 

 have the three distal joints well haired, while the hairs on their 

 femoral part are shorter and less numerous, and the trochanter 

 has only some hairs on the most distal part; the first joint of 

 the antennae has a very moderate number of hairs. 



Sexual differences well developed. In the female the tar- 

 sus of fourth pair of legs normal, shaped as the preceding pair; 

 in the male the fourth tarsus (fig. i e) increases nearly gradu- 

 ally conspicuously in height from rather near the base to beyond 

 the middle, and it is above at the middle produced into a 

 moderately large, nearly regularly conical, slightly curved 

 process which is somewhat longer than deep at the base 

 and directed backwards and considerably upwards; this
