consisting of about 58-82 ocelli. Frons sinuated, median frontal tubercle a little higher than lateral frontal tubercles. Antennae usually 6 jointed, about 0.43 to 0.82 times as long as the body, with joint I and II dark. Flagellum from the pale joint III gradually darker towards the base of joint VI; processus terminális gradually slightly paler towards apex. Length of antennái joint from the third to the sixth as: 0.310-0.440, 0.170-0.297, 0.130-0.210, 0.090-0.130 for the basal part and 0.310-0.496 for the unguis, respectively, Processus terminális 2.3-5.5 times as long as base of joint VI, and 1-1.6 of the length of joint III. The third joint with about 0-4 secondary rhinaria and with 9-15 hairs (fig. 2). Tip of rostrum generally reaching to the middle of hind coxae; ultimate rostral joint about 0.190-0.230 mm long, 1.3-1.9 times as long as second joint of hind tarsi. Head and thorax sclerotized and pigmented; brown in colour. Legs, compound eyes, siphunculi, cauda, and genital plate brown. Transverse rows of indistinct imbrication on abdominal tergites anterior to the siphunculi. Metanotum fused with abdominal tergites I to VI forming a brown patch (in life black), tergites VH and VIII free; dorsal shield quite smooth. Marginal tubercles absent on mesothorax; mesosternal processes conspicuous, semi-globular. Marginal tubercles absent on metathorax and abdominal tergites; and spinal tubercles absent on abdominal tergites VII and VIII. Tergite Vin with 6-7 hairs, mostly with filamentary apices, placed in a row on posterior margin of sclerotic part of this segment; longest of these hairs 0.090 to 0.100 mm long, 3-3.3 times as long as basal diameter of antenna! joint III. Longest hairs on antennái joint III 0.0100.012 mm long, 0.33-0.40 times as long as the basal diameter of this joint. Siphunculi brown, conical shaped, and smooth with faint traces of several imbrications, with a circular incision below the well developed flange, '0,230-0.341 mm long, about 0.11-0.17 of the body length, about I. 6-2.8 times the length of second joint of hind tarsi. Cauda tongue-shaped, about 0.100-0.124 mm long, bearing 7 hairs about 0.8 times as wide at base as its length. Legs bearing numerous fine hairs. Hind tarsal joint II about 0.120-0.140 mm long. First tarsal joints with 2,2,2 hairs (Table 1). From Table 1 we can see that there were remarkable variations in the lengths due to the different host plants and localities (Measurements see Table 1). II. The larval instars in Nagykovácsi The first instar larva: In life yellow in colour. In mounted specimens body cval (fig. 3), very small about 0,640-0.825 mm long. Frons sinuated, median frontal tubercle a little higher than lateral frontal tubercles. Head and pronotum sclerotized; meso- and metanotum membraneous. Transverse rows of imbrication on abdominal tergites absent, membraneous. Antennae usually 4 jointed (fig. 4), about 0.3-0.5 times as long as the body. Length of antennái joint from the third to the fourth as: 0.080-0.145, 0.045-0.060 for the basal part and 0.070-0.130 mm for the unguis, without secondary rhinaria on the third joint. Processus terminális 1.5-3 times as long as base of joint IV, and 0.8 of the length of joint III. Tip of rostrum generally reaching to the past of hind coxae; ultimate rostral joint about 0.075-0.110 mm long, 0.8-1.5 times as long as second joint of hind tarsi. Siphunculi cylindrical, very small, about 0.040-0.060 mm long, about 0.05-0.09 of the body length. Cauda semi-circular, very small, about 0.030-0.035 mm long bearing 2 hairs about 0.5 times as wide at base as its length. The larva in this Instar has six well developed legs, bearing numerous fine hairs. Hind tarsal joint II about 0.070-0.085 mm long. First tarsal joints with 2,2,2 hairs (Measurements see Table 2). The second instar larva: In life yellowish green in colour. In mounted specimens body oval (fig. 5), about 1.116-1.488 mm long. Frons sinuated, median frontal tubercle a little higher than lateral frontal tubercles. Head, pronotum, antennae and legs sclerotized; other thoracic tergites and the abdominal ones colourless. Siphunculi and cauda brown. Transverse rows of imbrication on abdominal tergites absent. Antennae usually 5 jointed (fig. 6), about 0.4-0.75 times as long as the body. Length of antennái joint from the third to the fifth as: 0.150-0.270, 0.070-0.110, 0.0700.090 for basal part and 0,170-0,270 for processus terminális, usually without secondary rhinaria on the third joint. Third antennái joint divides during moulting, resulting in a third joint and the fourth joint, the latter club-shaped. Processus terminális 1.8-3.8 times as long as base of joint V, and 0.6-1.8 times of the length of joint III. Tip of rostrum generally reaching beyond the hind coxae; ultimate rostral joint about 0.140-0.170 mm long, about 1.3-1.7 as long as second joint of hind tarsi. Siphunculi short, conical, about 0.120-0.170 mm long, about 0.08-0.15 times as long as body length and about 1-1.7 times length of second joint of hind tarsi. Cauda semicircular, about 0.050-0.055 mm long, bearing 4-6 hairs, 0.5 times as long as basal width. Legs
