 from before middle. 



Hindwing with a cubital pecten, vein 2 from 2/3, 3 from angle, 

 4 separate from 3, remote from 5 at base, 6 and 7 stalked. 



Male genitalia: Tegumen weak, higher than broad, top obtuse. 

 Uncus absent. Tuba analis moderate, developed, supported by a 

 transverse band (subscaphium). Valva characteristic, triangular, 

 outer angle produced, with a long pencil of bristles (Spc2), with a 

 strong triangular blade at its foot, a large patch of bristles in disc 

 (Spci) ; cucullus thinly bristled, sacculus narrow, complete. Aedeagus 

 very short, anellus broad, cup-shaped. 



Type species: Bubonoxena sjpirographa, new species. 



A speciaUzed genus, belonging to the Olethreutini, with a charac- 

 teristic neuration. The nearest genus is Syntozyga Lower from Aus- 

 traha. There seems also to be a connection with Bactra Stephens, 

 and with the Eucosmini.
