Exuviae. Male. Length 4 mm, stout, pale yellowish white, the 

 wing cases extending to the third, the leg cases to the fourth, and

 each of the abdominal segments is rather thickly coyered with long,

Fig. 36 Cincticorniasobrina. a, dorsal aspect of the third abdominal 

 segment of the pupa; h, 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 triangtilar 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 

 segm.ent, 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 segm.ents in the m-ale is entirely 

 covered with the stout, chitinous spines 

 observed in the opposite sex only on the 

 basal third of the segm.ents.
