posteriorly bounded by a transverse obtuse ridge which is highest in the centre ; 

 in wildei, moreover, the post-vaginal plate is flat, slightly concave, and smooth, 

 not wrinkled except laterally. 

 We have two subspecies : 



(a) 0. phalaris phalaris (text-fig. 1). 



Literature as above, the female figured in the Revision and the male figured 

 in Seitz belonging to this subspecies. 



A very deeply coloured geographical race, recognised by the deep chestnut 

 colour of the dark portions of the underside, both on body and wings. 



Length of forewing : <J, 56-58 mm. ; ?, 58-61 mm. 



Hah. Dutch and British New Guinea, a series of both sexes, some col- 

 lected by Meek and others by Pratt. Type from the Nmay valley in the 

 Arfak Mts., 3,500 ft., Nov. 1908 to Jan. 1909.

Fia, 2 — O. wildei. 



Fia. 3 — 0. a. celebenaia. 



(b) 0. phalaris carycina subsp. nov. 



$. PaUidior, magis ochracea, linea obliqua costali antemediana ante cellulae 

 angulum posticum posita. 



Long. al. ant. 56 mm.
