the base; it is nearly three times as long as broad. The front margin is straight, the 

 hind margin is feebly curved at the apex; it is not serrated but the hairs fringing it are 

 thicker, stouter, and more spine-like, than the hairs covering the sides of the joint. All 

 the preceding joints, as well as the metacarpus, are richly covered with hairs all around; 

 the hairs fringing the front margins of the joints are much longer than the hairs on 

 the sides and along the hind margins, being very slender and soft, curved at the apex. The 

 dactylus is stout, curved, half as long as the metacarpus; along the middle of the hind, 

 concave margin it is armed with about a dozen bristle-like spines. The base of the 

 dactylus forms a thick heel, at the hind corner of this heel there is a circular hole, the 

 outlet for the glands which are richly developed within the other joints of the leg. 



The second pair (PI. VIII, fig. 10 and 11), reach a little beyond the apex of the 

 tibia of the third pair. The femur is somewhat shorter than the four following joints 

 together, a little narroAver at the apex, and more than three times as long as broad at 

 the base. The genu is more long than broad. The tibia is longer than the genu, narrow 

 at the base, with bulging sides; the hinder loAver corner is rounded, not at all produced. 

 The carpus, without the carpal process, is much shorter than the two preceding joints 

 together; the front margin is convex, as long as the front margin of the metacarpus, the 

 hind margin is nearly straight. The carpal process is strongly developed, longer than the 

 rest of the joint; the hind margin is straight, closely set with a great number of very short 

 spines; the front side is narrowly hollowed, gouge-shaped, both the edges or margins are 

 closely set with numerous short spines; the apex is rounded, armed with a long, strong 

 terminal spine, as in the first pair; the front margin, with the terminal spine, is just as 

 long as the hind margin of the metacarpus. The metacarpus is almost linear, more than 

 three times as long as broad; the front and hind margins are straight, the hind margin 

 is closely set with short, spine-like hairs. The hair-covering of all the joints is similar 

 to that in the preceding pair. The dactylus is more strongly curved than in the first 

 pair, but armed in the same manner; it equals a third of the metacarpus. Glands as in 

 the preceding pair. 



The third and. fourth pairs (PI. VIII, fig. 12) are equal in length and similar in 

 shape. The femur is only a little longer than the femur of the second pair, the upper 

 half is narrow, the lower half more dilated, the joint being twice as broad at the apex as at 

 the base; at the front margin there is a long, narrow groove for the reception of the next 

 following joints when the leg is bent upwards. The genu is considerably more long than 

 broad. The tibia is as long as the genu. The carpus is somewhat longer than the 

 tibia, the hind margin is straight, not serrated. The metacarpus is as long as the carpus, 

 and only a little narrower; the front margin is feebly curved, the hind margin is straight, not 

 serrated, but closely set with short, spine-like hairs. The hair-covering is more rich on 

 the first four joints than on the metacarpus, especially is the lower part of the metacarpus 

 comparatively naked, and the hairs upon it are shorter. The dactylus is curved, smooth, 

 about a fourth as long as the metacarpus; at the base it shows a broad heel, with a cir- 

 cular hole, the outlet of the glands. The glands are richly developed within all 

 the joints.
