New York State Museum; Science; Science. a b > [~ Fig. 36 Cincticornia sobrina. a, dorsal aspect of the third abdominal segment of the pupa; b, lateral view of the same, enlarged (original) heavily chitinized triangular spines (figure 36), the entire surface being uniformly dotted with the same. Terminal segment broadly rounded, with a roundly triangular area bounded by an irregular chitinous thickening, the posterior lateral angles marked by con- spicuous rounded chitinous processes. Female. Length 3 mm, stout, pale yellowish, the thoracic horns long, slender, curved, the wing cases extending to the third abdominal segment, the leg cases to the fourth, the dorsum of the abdominal segments with a treble row of short, stout, heavily chitinized spines on the basal third, the row on the last segment being double, the posterior two-thirds of the abdominal segment with the surface thickly dotted with minute triangular points. The exuviae differs markedly from those of Asphondylia in the peculiar ornamentation on the dorsum of the abdominal segments. There is also a marked sexual difference, the antennal sheath of the male having about sixty distinct annulations, approximately one to each circumfilum. The dorsum of the abdominal segments in the male is entirely covered with the stout, chitinous spines observed in the opposite sex only on the basal third of the segments. Male. Length 3 mm. Antennae extending Fig 3y ^nctic to the second abdominal segment, sparsely ' nia sobrina Fifth haired, light yellowish; 14 segments,#the fifth antenml ment of with a length two and one-half times the male> enlarged (ori. diameter, and 4 circumfili; terminal segment ginai) slightly reduced, tapering to an obtusely rounded apex. Palpi; the first segment irregularly subquadrate, swollen distally, the second one-half longer, subrectangular, the third.
