showing through as slight green shadows on the upperside ; an additional 

 narrow dark patch more or less developed on the hindwing beneath, between

Fergusson Island, October — December 1894 (A. 8. Meek), type S and 2 $? ; 

 Milne Bay, British New Guinea. December 1898 — Februaiy 1899 (A. S. Meek), 

 (J, 2 ?? ; Kumusi River, N.E. British New Guinea, low elevation, August 1907

15, Hemithea wuka Isabella subsp. nov. 



?. Forewing slightly broader still than in w. wuka Pagenst. ; postmedian 

 line rather more excurved ; some greyish shading in distal area, indicating faintly 



the position of the blotch beneath ; terminal dots and fringe yellower. Hhid- 



wing with similar distinctions, the outward projection of the postmedian line 

 still more pronounced. Forewing beneath with subterminal blotch or half- 

 band from tomus almost to R' and very faint shadow-band anteriorly. Hind- 

 wing beneath with the usual apical blotch long and strong, a tornal blotch 

 nearly as on forewing. 



Isabel Island, Soh luons. June 4 — July 9, 1901 (A. S. Meek), type in coll.

 narrowly white. Palpus in $ with third joint longer than in the ussuriaria group. 

 Thorax above green. Abdomen paler.

 scarcely touching C, yet approaching much more closely than in the ussuriaria 

 group ; dull green ; costal edge very narrowly ochreous, with fine blackish 

 dots ; lines white, very fine ; antemedian indistinct or obsolescent, slightly 

 excurved in cell and incurved about M ; postmedian at nearly two-thirds, verj' 

 gently curved anteriorly, then almost straight or with an exceedingly slight 

 inward cun-e in its posterior half ; cell-dot not or scared}' discernible ; no 



terminal line ; fringe unmarked. Hindwing shaped about as in subexpressa 



Walk, and contracta Warr., the abdominal margin being considerably elongate, 

 the tail at R' well developed ; antemedian line wanting, postmedian slightly 

 or scarcely sinuous, very feebly bent at R'.
