( 3o3 ) 



line at two-thirds, irregularly dentate ; luniilate vertical to vein 4, inwardly obliijue 

 to submediau fold, then again vertical to inner margin ; snbmarginal line flesh- 

 coloured, strongly dentate, edged on both sides with deep blackish-brown suifusion ; 

 marginal spots black ; fringe flesh-colour, mottled with dark beyond vein-ends ; 

 cell-spot linear, black. 



Hindwiiu^s : with the blaek-s off used basal area angularly edged and nearly 

 reaching outer line, connected with it by black-brown scales which are produced in 

 a denser shade across marginal field to the hindmargin ; cell-spot black and linear ; 

 snbmarginal line more obscure. 



Underside of forewings ochreous along costa, rnfous at base of cell, rufous and 

 j)urplish-grey below ; a broad black margin with series of white submarginal 

 spots ; ajiex jialer ; cell-spot oval, black, followed by a sijuare white blotch ; 

 bindwings dull yellow, with small dark cell-spot ; the marginal border without 

 submarginal spots. 



Head, palpi, and abdomen rufous-grey ; thorax much mixed with brown-black 

 scales. 



Expanse of wings : 52 mm. 



Two ? ? from British New Guinea ; one in good condition from S. Joseph 

 Eiver ; the other, somewhat worn, from River Aroa (Weiskej. 



This species appears to be the counterpart in New Guinea of Guenee's 

 Australian species emiliuria, in which the black tints are still further developed. 



30. Hypochroma viridicoma interrupta subsp. nov. 



A much handsomer form than the type from Tugela ; the green and pnrple- 

 brown tints more intense and sejMrate ; the whole basal two-thirds of forewing 

 green as far as the outer line, which is pnrjile, not dark green, followed by a pale 

 green line ; the inner line is formed of distinct purj)le patches between the veins ; 

 outer area wholly suffused with purple-brown, except the space reaching from vein 3 

 to halfway between 4 and 5, which is green like the basal and central areas ; the 

 submarginal line is formed of silvery white and green scales. The hindwings are 

 mainly purple, except the green sub-basal tufts, the green line following the dark 

 outer line, and the green space above vein 3 across the marginal area as in forewings. 

 Below, the extreme apex only is greenish white, not broadly white as in the type 

 form, and the discal spots are roughly 8-shaped. 



One ? from Florida, Solomon Islands, January I'jiil (Meek), expanding 4,smm. 



Subfamily GEOMETRINAE. 

 37. Acrortha flexicosta Warr. (Nov. Zool. III. p. 361). 

 The type described was from ('eylon. I have lately seen a very perfect example 

 from the Khasia Hills. To the original description may be added : costa of fore- 

 wings dotted with fuscous and pale grey ; middle segments of abdomen on dorsum 

 black-brown, the rest reddish tinged. 



The genus is an offshoot of Hemilhea, distinguished liy the peculiar slicing oft' 

 of the costa at apex. 



3s. Gelasma cynthia Warr. 



The species was described from a single i from the island of St. Anna (Nov. 

 Zool. VI. p. 23). It appears to be fairly common in the Solomon Islands, Florida,
