OENOCHBOMINAE. 



1. Ozola ramifascia sp. nov. 



3 ? . 42 — 46 mm. 



Head, collar, patagia, tegulae and part of pectus orange, the face 

 with a transverse dark band below middle, the palpus dark-mixed on 

 outer side. Thorax, abdomen and legs dark-drab to blackish, the 

 venter paler, with some ochreous, somewhat mixed with orange. 



Fore wing narrow, but not falcate, termen smooth, blackish ; the 

 costal edge as far as the band dotted, or minutely strigulated, with 

 white ; an oblique white band from costa somewhat beyond middle 

 to hind margin close to tornus, its anterior end 2 — 3 mm. wide, its 

 posterior 3 — 5 mm. (usually broad), its proximal edge straightish, its 

 distal usually with minute irregular teeth and a rather stronger one 

 at (behind) K 2 ; a small tapering branch from its proximal edge at 

 M 2 to SM 2 ; a small, usually less pure white patch on hindmargin 

 just proximal to (generally confluent with) this branch ; a terminal 

 line of the ground-colour ; fringe almost concolorous. Hind wing 

 with the band narrower at costa, broadening rapidly, branching at 

 or before M 2 , but with its proximal branch the broader, reaching the 

 abdominal margin a little beyond the middle, its distal branch variable, 

 rarely reaching hindmargin, occasionally rudimentary. 



Underside the same.
