to the third, but otherwise essentially similar in structure (PI. 2, 

 fig. I and PI. 3, fig. 2 — 6). The coxaj are mentioned above. 

 The trochanter is stout, cut off" from the femur by a rather oblique 

 articulation; both on the upper and the lower side is found a 

 group with 4 — 9 small sense pits (fig. 2, 4 and 6, s); on the lower 

 side of the two posterior pair of legs 4 or 6 of them are arran- 

 ged in a row, the others lying a little apart; on the upper side 

 and on the first pair the arrangement is somewhat more irregular. 

 The femur is stout with the one side considerably arched. The 

 tibia has a very peculiar shape, it increases strongly in thickness 

 from the base towards the middle, and on the ist pair a little 

 before, on the 3rd pair a little outside the middle begins a pecu- 

 liar plane, owned to the circumstance that the tibia on the outer 

 side is cut off very obliquely, so that its distal end becomes 

 slender; the margins along this long, a little excavated and more 

 membranous plane is trimmed all around with long setae. Spurs 

 are wanting. The tarsi contain 3 joints, the 2 first of which (PI. 

 3, fig. 3 and 5) are strongly expanded, almost circular, the 3rd 

 is slender, somewhat clavated, articulated at the middle of the 

 upper side of the foregoing joint and ending with 2 uniform claws; 

 empodium is wanting. In the tarsi of the ist pair (fig. 3) the 

 basal joint seems to be somewhat broader than in the 2 other 

 pairs, but besides the 2 broad joints in all the tarsi are mem- 

 branous on the interior side and along the lateral margins on the 

 upper side in such a way that they become soft cushions, which 

 are able to be much extended in living specimens, while they 

 collapse very much in specimens preserved in spirit and especially 

 in exsiccated specimens. The inferior side of these 2 joints is 

 closely studded with the usual fine and short fixing hairs (such hairs 

 are found in the same w'ay f. inst. on the 3 basal joints in the 

 tarsi of Cerainb]'cidit)\ the 3rd joint is studded with similar hairs 

 on a small area near the apex (fig. 2). — About the endowment 

 of the legs with set^e and hairs the figures give a sufficient idea, 

 e. Abdomen. In i^roportion to the thorax this seems to 

 be somewhat longer and a little more slender in the male (PI. 2, 

 fig. 2) than in the female with youngs (fig. i). In both sexes 

 it is somewhat longer than head and thorax together; the tergite 

 of the ist segment is short bending downwards laterally and a
