On the distal tarsi, rings are well developed at the base of all the segments; on the fore- and midiegs, the distal tarsal segments often without light rings.

On the 8th tergite (in which the backward extended lobe with the short spines is absent) and on the gonocoxite, some setae bear the typical form of straight nail-like spines. Two more similar spines seen at the apex of the lateral lobe of the gonofurca. Fourth instar larva. This has relatively indistinctly branched*inner frontal setae (not more than 5 branches); median frontal setae usually with not less than two branches (2-4). The comb has more than 120 scales. Median seta posterior to the comb (9) is shorter than the saddle. Distal teeth of the pecten set very widely apart and des- cend without a specific order beyond the center of the siphon almost to its distal one third. Seta 5 at the base of the lateral valve of the stigmal plate flabellate. Setae anterior to the common base of ventral. Fig. 80.
