c? ? . Palims lav,s;;(>, prominent, first segment slightly, second more or less 

 distinctly angulate laterally at ajjex, third very small. Head and thorax with a 

 mesial crest. Eye small, laslicd. Antenna long, reaching beyond apex of cell in 

 (J, slender, not clnbbcd, gradnally narrowed to a long hook, end-segment short. 

 Hindmargin of mernm of mid- and hindcoxa not augnlate. Abdominal spines at 

 tiie edges of the segments weak, elongate, those on tlie sternites esijecially weak, 

 partly modified to scales ; seventh sternite of ? trapezoidal, its apex not mem- 

 branaceons and not spinose. Tarsi slender, hindtarsus at least half as long again 

 as cell of hindwing measured along SC! ; midtarsus with comb — i.e., tlie proximal 

 spines of the fourth row somewhat prolonged and thin. Distal margin of forewing 

 irregular, sinuate or lobed at apex, lobed or angulate at R^ ; SO" and R' of hindwing 

 from upper angle of cell, R^ central or below centre of cell, D' transverse, D^ 

 oblique, lower angle of cell acnte, D^ about half the length of D'' or not much 

 shorter than D^ 



cJ. Ninth tergite asymmetrical, more or less twisted. Tenth tergite flat, hairy, 

 apically truncate or sinnate, about four times as long as broad in middle (PI. XLIII. 

 f, 4. 5) ; sternite much longer than tergite, curved downwards, produced into a 

 long, sharp point, edges of proximal half somewhat raised, especially in middle of 

 segment ; this single process is the result of asymmetrical development. ( 'laspers 

 large, not quite symmetrical ; a j)atch of numerous small friction-scales ; harpe of 

 right and left side unequal, the right ,one the longer, the left produced into 

 a long, cylindrical, distally acuminate process (PI. XLVI. f. 9), or the left process 

 reduced, the right one always prolonged (PI. XLVI. f. 12. 13). Penis-sheath ending 

 in a short dentate process, or cariniform at end (PI. LIII. f. 21. 23. 24. 37). ■ 



?. Vaginal orifice in a large cavity. ■ 



Early stages not known. 



Ihth. Trojiical and Subtropical America, exclusive of the West Indies, from 

 Mexico to Southern Brazil. 

 Seven species. 



The obliteration of the left process of the tenth sternite of the c? and the 

 asymmetry of the ninth tergite are peculiar features to which we have referred in 

 the Introduction. i
