The data below + are the values of the Standard Error. as: 0.070,0.035-0.045, 0.050 for the basal part and 0.080-0.090 for the unguis, without secondary rhinaria on the third joint. Processus terminális 1.6-1.8 times as long as base of joint V, and 1.1-1.3 times the length of joint III. Tip of rostrum generally reaching to the middle of hind coxae; ultimate rostral joint about 0.085-0.090 mm long, 1.1-1.4 times as long as second joint of hind tarsi. Siphunculi, very small, about 0.045-0.050 mm long, about 0.05-0.08 of body length. Cauda semi-circular, very small, about 0.025-0.035 mm long, bearing 2 hairs, about 0.3 times as wide at base as its length. Hind tarsal joint II about 0.065-0.080 mm long. First tarsal joints with 2, 2, 2 or 2, 2, 1 hairs. (Measurements see In Table 2.) The second instar larva: In life yellow in colour. In mounted oval about 0.946-1.085 mm long. Dorsal sclerotization as in the first instar larvae. Antennae, siphunculi and cauda pale in colour. Transverse rows of imbrication on abdominal tergites absent. Antennae usually 5-jointed, about 0.4-0.6 times as long as the body. Length of antennái joint from the third to the fifth as: 0.1200.180, 0.060-0.070 and 0.060 for basal part and 0.110-0.145 for processus terminális, usually without secondary rhinaria on the third joint and with about 1-4 hairs. Processus terminális 1.82.4 times as long as base of joint V, and 0.6-1.2 times the length of joint III. Tip of rostrum generally reaching to the top of hind coxae; ultimate rostral joint about 0.095-0.100 mm long, about 1.0-1.2 as long as second joint of hind tarsi. Siphunculi, cylindrical or slightly tapering, about 0.070-0.080 mm long, about 0.06-0.08 times as long as body length and about 0.7-0.9 times the length of second joint of hind tarsi. Cauda semi-circular, about 0.040-0.050 mm long, bearing 4-5 hairs, 0.4-0.5 times the basal width. Legs bearing numerous fine hairs. Hind tarsal joint II about 0.085-0.100 mm long. First tarsal joint with 3, 3, 2 hairs. (Measurements see in Table 2.)
