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 ^ n ctic 

 to the second abdominal segment, sparsely ' n i a 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 g i na i) 

 slightly reduced, tapering to an obtusely 



rounded apex. Palpi; the first segment irregularly subquadrate, 

 swollen distally, the second one-half longer, subrectangular, the third
