bearing numerous fine hairs. Hind tarsal joint II about 0.100-0.110 mm long. First tarsal joints with 2,2,2 hairs (Measurements see Table 2). The third instar larva: In life yellowish green in colour. In mounted specimens body wide oval (fig. 7), about 1.612-1.736 mm long. Frons sinuated, median frontal tubercle a little higher than lateral frontal tubercles. Head, pronotum, antennae, legs, siphunculi and cauda sclerotized; brown, other thoracic tergites and the abdominal ones colourless. Transverse rows of imbrication on abdominal tergites absent. Marginal tubercles absent on mesothorax; mesosternal processes conspicuous semi-globular. Tergite VIII bearing 6 hairs with filamentary apices, placed in a row on posterior margin part; about 0.070 mm long, 2.7 times as long as basal diameter of antennái joint III. Antennae usually 6 jointed, about 0.5-0.7 times as long the body. Length of antennái joint from the third to the sixth as: 0.130-0.220, 0.120-0.170, 0.100-0.145, 0.085-0.100 for basal part and 0.270-0.355 for unguis, usually without secondary rhinaria on the third joint. Processus terminális 2.7-4.1 times as long as base of joint VI, and 1.2-2.7 times of the length of joint III. Third antennái joint divides during moulting, giving the third and the fourth joint. Tip of rostrum generally reaching beyond the hind coxae; ultimate rostral joint about 0.170-0.195 mm long, about 1.3-1.6 as long as second joint of hind tarsi. Siphunculi conical and smooth, with a circular incision below the flange, about 0.190-0.220 mm long, about 0.11-0.14 times as long as body length and 1.5-1.8 times length of second joint of hind tarsi. Cauda semi-circular about 0.060-0.070 mm long, about 0.5 times as long as its basal width, bearing 4-6 hairs. Legs bearing numerous fine hairs. Hind tarsal joint II about 0.120-0.130 mm long. First tarsal chaetotaxy: 2,2,2 (Measurements see Table 2). The fourth instar larva: In life yellowish green in colour. In mounted specimens body wide oval (fig. 8), about 1.808-2.093 mm long. Dorsal sclerotization as in the third instar larva. Marginal tubercles absent on mesothorax; mesosternal processes semi-globular

. Tergite VIII bearing 6 hairs about 0.080-0.090 mm long, 3 times as long as basal diameter of antennái joint HI. Antennae 6 jointed

; about 0.5 to 0.7 times as long as the body. Length of antennái joint from the third to the sixth as: 0.200-0.250, 0.145-0.190, 0.110-0.150, 0.090-0.105 for basal part and 0.305 to 0.385 for unguis; usually without secondary rhinaria on the third joint. Processus terminális 2.9-3.7 times as long as base of joint VI, and about 1.2-1.9 times of the length of joint ül. Tip of rostrum generally reaching to the middle of hind coxae; ultimate rostral joint about 0.180-0.195 mm long, about 1.4-1.6 as long as second joint of hind tarsi. Siphunculi conical and smooth, with faint traces of several imbrication, with a circular incision below the well developed flange, about 0.210-0.250 mm long, 0.10-0.14 times as long as body length and about 1.6-2.1 times length of second joint of hind tarsi. Cauda semi-circular, about 0.070-0.080 mm long, about 0.5 times as long as its basal width, bearing 6-7 hairs. Hind tarsal joint II about 0.120-0.130 mm long, first tarsal chaetotaxy: 2,2,2 (Measurements see Table 2). REFERENCES BURGER, H.C .
