SOUTH AFRICAN BAGWORMS. 607 



on one side densely ciliated ; antenna? of female shorter than 

 half of costa, serrate and ciliated; fore tibiae without a 

 process ; mid tibias with end spurs, inner spur slightly shorter 

 than outer ; hind tibiae with very long mid nnd moderate 

 hind spurs; tarsEe with long smooth scales. 



Fore wing of male about twice as long as broad; costa 

 and inner margin nearly parallel ; costa gently arched ; 

 apex well rounded ; termen ublique, slightly arched ; tornus 

 rounded ; inner margin first straight, then well curved 

 towards base. 



Fore wing in female lunger, nearly three times width of wing. 



Vein la forms a fork with lb of over one-third of Ih ; Ih 

 much curved towards upper median at two-thirds; Ic faint 

 and only present for about half, never reaching termen ; 

 lower median slightly curved upwards; cell nearly two-thirds 

 of wing; 2 from beyond seven-eighths of lower median; o 

 from lower angle ; 4 and 2 from nearly the same distance 

 of lower angle ; 5 from nearer 4 than 4 from 3 and curved 

 at middle ; 6 from two-thirds disco-cellular, which is a little 

 ourved betweeii 5 and 6 ; 7 from near upper angle or from 

 areole ; areole formed l>y 8 or by stalk of 7, 8 and stalk of 

 9, 10; 9 and 10 from areole, either stalked or free ; 11 from 

 near and before middle of upper median ; 12 parallel to 11 ; 

 fork of veinlet in cell very long, from half to one-third (in 

 O. stygialis the upper part of the fork is absent). 



Hind wing triangular, rather longer in female than in 

 male ; costa arched at middle; apex rounded ; termen gently 

 hollowed at between 2 to 6 ; tornus well rounded; inner 

 margin slighth^ hollowed out; vein le rather faint; cell half 

 of wing ; 2 from two-thirds of lower median ; 4 from lower 

 angle ; 8 from middle of 2 to 4 ; 5 from one-third, 6 from 

 two-thirds of disco-cellular ; 7 from upper angle ; upper 

 median curved beyond middle ; 8 somewhat parallel to costa. 



The type of this genus is unknown to me and comes from 

 Delagoa Bay.
