New Geometridae from Central Ceram 295 



white than above and with a narrow bluish-white circumscription 

 which makes it appear larger. Hind wing with white costal patch, 

 otherwise blue to beyond end of cell and to tornus ; a brownish-grey 

 distal border, separated in its broad anterior part from the blue colour 

 by an ill-defined patch. 



Central Ceram : Manusela, 6,000 feet, October to December, 1919. 



The exact systematic position somewhat doubtful. 



26. Milionia dispar sp. nov. 

 <? ? . 31—35 mm. 



Structure of the preceding, the female antennal ciliation very short; 

 E 1 of fore wing separate or connate, not stalked. Head and body 

 coloured as in the preceding, the yellow abdominal patch of the female 

 much duller (reddish-buff), and extended to anus. 



$ . Wings shaped nearly as in the preceding. Fore wing brownish- 

 black, shot with blue at base ; a large orange patch proximally to 

 middle, its main portion roughly oval but flattened anteriorly, (at C), 

 running rather obliquely outward (so that its distal edge crosses M near 

 the end of the rather long cell), nearly reaching to SM 2 ; variable 

 extensions of this patch proximally ; a slender, strongly curved orange 

 band well beyond cell, reaching from SC 5 to fold ; fringe whitish. 

 Hind wing broadly black apically and terminally, shot with blue on 

 abdominal margin ; a large orange patch from base, reaching costally 

 to beyond two-thirds, posteriorly to fold, its distal extremity 3 — 4 mm. 

 from termen ; fringe whitish. 



Underside similar, the distal borders in places suffused with 

 brownish. 



? . Wings similarly shaped. Fore wing with the orange parts 

 much paler (whitish-buff), ampler, the extensions of the proximal blotch 

 reaching the base ; termen broadly suffused with orange-brown, leaving 

 irregular dark streaks on the veins. Hind wing with the orange parts 

 of the male similarly lightened, the apical and distal border entirely 

 dull orange. Both wings predominantly dull orange ; fore wing with 

 costal edge, discal band and abdominal margin irregularly dark blue- 

 grey, proximal area in one example whitish-buff; bind wing also 

 paler proximally, a large triangular area at abdominal margin, dark 

 blue-grey.
