The distal part (1/15 ) comprises an area with annular ligaments (Figs. 7, 8), tapering to the point- ed and perforated tip (Figs. 9, 10). The estimated number of pores per hair is about 400; their diameter reaches um. The hairs are inserted in raised cupolae, from which they may be detached (Fig. 11).

. Bonn zoological bulletin. Zoology. Fig. 1. Larva of Streblote panda, last instar. Left: at rest, right: disturbed, showing the two urticating crevices. ated longitudinally from the base onwards over 14/15 of its length (Fig. 7). The distal part (1/15 ) comprises an area with annular ligaments (Figs. 7, 8), tapering to the point- ed and perforated tip (Figs. 9, 10). The estimated number of pores per hair is about 400; their diameter reaches um. The hairs are inserted in raised cupolae, from which they may be detached (Fig. 11). Different types of integumentary structures are associat- ed with the urticating apparatus: - Some thirty white scales, mm long, are lined up along the posterior edge of each urticating pocket (Fig. 12), whereas dark scales are spread over the rest of the segment (Figs. 13, 14). The white scales, which have the form of a strongly elongated tennis racket (some visible in fig. 3), are covered with longitudinal ribs made up of overlapping elements resembling roof tiles (Fig. 15). This structure is analogous to that of scales found on butterflies' wings. Five-six nonporous sensilla chaetica, mm long, are found on the pair of white D1 verrucae in the anterior area of the meso- and metathorax (Figs. 16, 17). Other sensilla chaetica, mm long, are found among the urticating hairs (Fig. 18). Sensilla filiformia, mm long, are found in lat- eral tufts on the meso- and metathorax (Fig. 16).
