The front leg, Fig. 11, is little more than half the length of the succeeding legs, but is more robust. It bears three stout spurs on the inner angle next to the tarsus and one isolated spur on the distal margin. On the inner margin of the basal segment of the tarsus there is a single row of short stout spines. The inner surface of the tibia bears numerous very short spines, The inner surface of the femur is sparsely armed with short triangular teeth. The coxa, on its inner margin, has a few short spines and over its entire snrface has rows of fine, short hairs me thase described for the frons. The two succeeding legs (fig. 12 shows the hind leg), differ from the front leg in being longer and less robust and in having fewer and weaker short spines. Each of these legs has but one tibia1 spur.
The Abdomen is cylindrical and almost uniform in circumference throughout its length.
The humps on the first segment are not aeatly developed. The lateral
humps bear an area of short curGed spines whose points are directed forward. The
gills are distributed on segments 2-8, above and below the lateral line, as diagrammed in Fig. 10. The lateral line, near the ca11daI margin 01 the seventh abdominal seg- ment, ends at the beginning of a fleshy raked he, Fig. 16, which crosses the suture between the seventh and eighth segment and, inclining upward, extends to the caudal margin of the eighth segment. Each side of this fleshy line is armed with curved, bifurcate spines directed backward. The a d hooks and the arrangement of set= on the last abdominal segments are shown in Figs. 16 and 17, Pupa: Length, 13 mm.
Mandible Fig. 20. Tarsi flattened and fringed on each side by a row of black swimming hairs. Lateral line black. A narrow black line
parallels the lateral line beneath, to the caudal margin of the eighth segment, where the two converge. A narrow black line above the lateral line contains the spiracles. Abdominal segments 2-9 with paired tufts of hair near their caudal margins above. On the caudal margin of the first abdominal segment there is a pair of lobes, Fig. 18, covered with sharp spines.
Above these lobes are sparse backward-pointing teeth. The chitinous plates of the abdomen are shown in Fig. 18. The posterior end of the pupa is represented in Fig. 19.
