ide; coxa small, negligable. Leg II (fig. 6) has threes 

 plumose hairs on lower side of tarsus, about five fine bristles 

 near tip, three bristles on dorsal side, and a weekly plumose 

 hair on outer side; tibia with two plumose hairs on lower 

 side, and a fairly long bristle on dorsal side; genual with 

 a weekly plumose hair on under side at the distal end and 

 a long bristle on dorsal side at the proximal end. This 

 bristle is bowed downward and posteriorly into the form 

 of a hook. Femur blade-like, equal in length to tibia and 

 tarsus, curved almost at a right angle, with a curved 

 bristle on dorsal side at apex of the curve and a long one on 

 postero-ventral surface, each with a few barbs, a decided 

 tooth on ventral surface near proximal end; coxa very 

 much reduced, with a single bristle directed parallel to 

 femur. Leg III (fig. 7) three plumose hairs on lower 

 surface of tarsus, four fine bristles at tip, four on dorsal 

 side and one on outer side; tibia with a plumose hair on 

 lower side, an outer lateral bristle and a long dorsal one; 

 genual small, with an outer bristle and a shorter dorsal 

 one; femur triangular, blade-like, with lower edges gently 

 curved, a weekly plumose hair on lower edge and a fairly 

 long curved bristle above rising from a distinct notch; 

 coxa gourd-like in outline but flat, the neck on one side, 

 a long bristle arising from the lower surface. Leg IV (fig. 8) 

 with very slender tarsus having three fine bristles near 

 tip, three plumose hairs on the lower side, one bristle 

 on outer side and two bristles on dorsal side; tibia with 

 two plumose hairs on the ventral side on distal half, a 

 long bristle near posterior-most ventral plumose hair and 

 one long bristle on dorsal side ; genual elongate and with 

 two long bristles on dorsal side, the anterior-most being 

 the longest; femur broad, bladelike, suddenly constricted 

 at each end to form the articulation, a very thick, rough, 

 spike-like bristle on dorsal side and a bristle on lower side; 

 coxa large, blade-like, rounded above into a lop-sided lobe, 

 ridged along base from which there arises a fairly long, 

 slender bristle, posterior end produced downward to form 

 an articulating head.
