Hypochrosis prouti, sp. n. 



<$ 2 . Head, thorax, and abdomen palish grey, the latter 

 with laterals and venter yellow. Both wings pale grey with 

 a central oblique olive-green stripe. In the primaries the 

 stripe is straight and above it is a wedge-shaped black costal 

 spot, and nearer the apex is another similarly placed and 

 shaped spot, but smaller ; up to the first spot the costa is 

 finely yellow. In the secondaries the green stripe is waved 

 and is edged externally by a very definite black stripe 

 about the same width as the green one. 



Expanse, <$ 42, 2 50 mm. 



Hab. Ekeikei, Mount Kebea, British New Guinea, 4000 

 and 6000 feet respectively ; March and April (A. E. Pratt).

Ectropis cessaria, ab. ochreocosta, ab. nov. 



£ . Head and collar umber-brown, prothorax ochreous 

 grey, rest of thorax and abdomen brown. Primaries burnt- 

 brown with the costa very broadly ochreous gi'ey, almost up 

 to the apex ; a trace of a median line and of a spotted post- 

 median one, a subterminal row of creamy dots terminating 

 at the apex in a fine short curved dash. Secondaries burnt- 

 brown with a submedian dark line and a dark spot at the 

 end of the cell, beyond which is a broadish, indefinite, darkly 

 irrorated, creamy band ; a trace of a dotted creamy line in 

 the subterminal area terminating in a creamy anal clash.

Paradromalia ambigua, ab. intermedia, ab. nov. 



<$ . Head, thorax, abdomen, and both wings dull brown 

 finely irrorated all over, with a marginal creamy patch 

 just above the tornus and another on the inner marginal 

 side of it on the primaries, whilst in the secondaries there is 

 a faint trace of a creamy postmedian line, more pronounced
