Third larval instar (Fig. 4): Oval, light brown with brown and yellow markings. White tubercles present on antennái joint II and on legs. Head about as long as wide. Antenniferous tubercles with tooth, pre- and postocular tubercles represented by some granules. Antennae thick, dark-brown fourth joint the longest. Pronotum flattened with narrow serrate lateral margin, collar region not visible. Median and lateral carinae visible, latter only on hind half of disc. Mesonotum wider than pronotum with serrate lateral margins. Hind border uniformly convex. Metanotum the widest, hind border strongly sinuated medially . Abdominal scent gland openings on segments III to V clearly visible. White tubercles along hind border of abdominal tergites. Connexival plates each with narrow lateral margin, strongly serrate only on post­erior segments. Pointed margin of segment IX surpassing apex of segment VIII. Glabrous areas on tergites 2:1:1, on s terni tes 1:2:1. Rostrum not reaching fore border of mesoster­num. Legs short and thick. Total length 2. 7-3. 4 mm , relative length of antennái joints I to IV as 10:21:13:25. Fourth larval instar (Fig. 5-6): Oval, yeUowish brown with sharp light yellow and brown or reddish brown markings. White tubercles on antennái joint II and on legs. Head ab­out as long as wide. Antenniferous tubercles with strong tooth, preocular tubercles blunt, postocular tubercles represented by granules. Antennae thick, second joint the longest. An­tenna brown, tip of joint II and apical 3/4 of joint III yellow. Pronotum with posteriorly point­ed serrate lateral margins, on o^ not reaching hind border (Fig. 5), but reaching it on male (Fig. 6). Fore border sinuated with marks of neck region. Median and lateral carinae as on third instar. Hind border of pronotum on male slightly rounded with medial tubercles reach­ing posteriorly, on female without such tubercle. Mesonotum with signs of scutellum and with wing pads not reaching hind border of metanotum. Lateral margin rounded, serrate Metanotum with lateral margin serrate and widening posteriorly, hind border sinuated. Ab­dominal scent gland openings clearly visible. White tubercles along hind border of abdominal tergites. Connexival plates each with more widened serrate lateral margin, posterolateral angles of these rectangular or acute angled on posterior segments. Lateral margins of seg­ment IX not reaching tip of lateral margins of segment VIII. Glabrous areas on tergites 2:1:1, on sternites 1:2:1. Rostrum reaching or slightly surpassing fore border of mesosternum. Legs thick. Total length: 3.7-4.9 mm, relative length of antennái joints I to IV as 13:35:21:31. Fifth larval instar (Fig. 7, 8): Male narrow, female broad oval, yellowish brown with sharp light yellow and reddish or dark brown markings. Antennái joint II and legs with white tubercles. Head about as long as wide. Antenniferous tubercles with strong pointed tooth. Pre- and postocular tubercles developed, latter blunt, both with granules. Pronotum with wide serrate slightly rounded lateral margin not reaching hind border on female. Median and lateral carinae strongly elevating, latter reaching beyond middle of pronotum anter­iorly. Fore border with expressed neck region on female. Hind border in male with median tubercles, those of female almost straight. Mesonotum with scutellum well visible, on male narrower than on female. Wing pads developed reaching 1/3 of second abdominal tergite. Lateral border of wing pads serrate. Wing pads of metanotum reaching beyond anterior border of second abdominal tergite. Abdomen broad on female, narrowing posteriorly on male. Abdominal scent gland openings well visible. Connexival plates each with developed serrate lateral margin, posterolateral angles rectangular or acute angled on posterior seg­ments. White tubercles more dense on wing pads and on connexival plates. Lateral margin of segment IX not reaching tip of those of segment VIII. Glabrous areas on tergites 2:1:1, on sternites (2)1:2:1; meaning that the lateral areas are oval and sometimes two centres are visible. Rostrum reaching fore border of mesosternum. Legs thick. Total length: 5-7. 2 mm, relative length of antenna! joints I to IV as 12:39:20:25. Author's address: Dr. T.
