Hypopygium shown in Fig. 84. Spines absent on the lobes of the 8th tergite. On each lobe of the 9th tergite, 7-11 setae (average 9). On each lobe of the gonofurca 3-5(more often4) slighdybent heavy setae. The form of the phallus approaches a rectangular parallel tubal struc- ture with a heavily sclerotized transverse distal margin. Fourth instar larva. Antennae shorter than the head; antennal tuft comparatively poorly branched (16-31, average 22 branches). The me- dian frontal seta moderately long; the ratio of its length to that of the head is 115-125% (average ). The comb usually with not less than 80 scales (65-90, average 75). The median seta posterior.
