PLATE 39 Egg of Mouralia tinctoides. enlarged x 36 First instar, immediately after emergence: Length, mm. Head, large, jet black, strongly bilobed; width about .38 mm., which is about twice the width of the average body segment. Body, cylindrical, sub-translucent. Color, ivory white. The first segment is topped by a prominent shield-shaped scutellum bearing two setae each side of the median line. There are three black papillae lateral to the scutellum, each bearing a seta. The body has five rows of setae each side of the median line. On the typical segment these are placed as follows: One placed anteriorly on the segment close to the median line. The next lateral seta is posteriorly placed on the segment. The third, laterally placed is anteriorly located, and the fourth, posteriorly located. The fifth is again anteriorly placed on the segment. Thus each segment alternates in its position in the usual typical manner. Each seta arises from a black tubercle. Legs, black. Prolegs concolorous with body. There are four pairs of prolegs, the anterior two being small and non- functional. Anal prolegs concolorous with body. Duration of the first instar, four days. Second instar, twenty-four hours after first moult: Head: .56 mm. wide; translucent ivory, with a number of blackish-brown spots over the crest and upper cheeks. Mouth parts, dark brown. Ocelli, black. Body, translucent ivory; cylindrical, the green food sub- stance showing through and giving the larva a slightly green tinge. Over the head and body the numerous black papillae give rise to colorless setae. Legs: Terminal two joints, black; proximal joint concolor- ous with body. 170.
