Fig. 2. Relative growth of second and fourth antennái joints (length of joints compared with width of head) DESCRIPTIONS OF THE LARVAL INSTARS II TO V Second larval instar (Fig. 3): Long oval, light brown with yellow markings. Head about as long as wide. White tubercles on antennái joint II and on legs. Antenniferous tubercles blunt with smaU hardly protruding tooth. Pre- and postocular tubercles not visible. Antennae thick, brown joint IV the longest. Pro-, meso- and metanotum with hardly serrate lateral margins. Median carinae visible on pronotum, lateral carinae represented by few white tubercles. Hind border of metanotum sinuated. White tubercles sparse on tergites. Abdominal scent gland openings clearly visible. Connexival plates with increasingly widely serrate lateral margins posteriorly, rounded on posterior segments. Lateral margin of segment IX strongly surpassing tip of that of segment VIII. Spiracles VIII laterodorsal. Glabrous areas on tergites 2:1:1, on sternites 1:1:1. Rostrum reaching hind border of mesonotum. Total length 1.5-1.7 mm, relative length of antenna! joints I to IV as 8:15:11:22.
