hairs by the anus, another between the first and second 

 epimera, a third between the third and fourth epimera, 

 and a fourth near the hind edge of the vulval plate. 



Legs rather short, the two hinder pairs scarcely 

 extending beyond the plumose hairs ; all the pairs are 

 of nearly equal thickness. Caroncles (PL XI, fig. 14) 

 large and rounded. Tactile hairs of first pair of legs 

 nearly twice the length of the tarsus ; those of second 

 pair about the length of the tarsus. There are the 

 following curved, slightly pectinated hairs on the legs, 

 viz. one on each coxa except the fourth pair, one on 

 each femur except the third, one on each genual except 

 the fourth, and one on each tibia. There is also a 

 small, curved, rod-like projection with a small globular 

 head in the middle of the anterior edge of each tibia of 

 the first two pairs, just under the tactile hair. There 

 are also a few fine hairs on the legs. 



MALE. 



The male is much smaller and more active than the 

 female ; the cephalothorax is longer in proportion to 

 its width, and the abdomen less square and less 

 flattened. 



The Plumose Hairs (PI. XI, fig. 18). The number 

 of what may be considered peripheral plumose hairs is 

 the same as on the female ; but they are not all so 

 truly peripheral as in that sex, and their character is 

 very different ; they are somewhat longer than those 

 of the female, but not nearly so wide ; they have the 

 rachis almost similar to that in the hairs of the female, 

 but the barbs diminish in length much more gradually 

 from near the base to the point ; they are parallel and 

 almost straight, standing forward and outward ; they 

 never turn forward at an angle near the tips in the 

 manner so characteristic of the female. There are 

 four pairs of similar hairs on the notogaster ; some of 

 these lying over some of the peripheral hairs causes 

 quite a bunch near the hind margin. All the plumose
