290 Netv Geometridae from Central Ceram 



? more uniformly rufous. 



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

 four $ $ , four ? ? . 



Nearest to dissociata Warr. (Nov. Zool. iv, 73, Luzon), distinguish- 

 able at once by the anteriorly more excurved postmedian lines, especially 

 the first one. Like that species, it is evidently variable, especially in 

 the $ ; two are redder than the described type, less unlike the ? 

 form, the fourth is a very beautiful aberration with the pale parts 

 almost clear white — ab. albifusa ab. nov. 



19. Xanthorhoe hedyphaes sp. nov. 

 c? . 32 mm. 



Structure of the preceding. Head and body darker greyish, the 

 irroration being predominantly blackish, the rufous elements weak and 

 dull (red-brown). Thorax above in part olive-green. Abdomen above 

 with paired black spots. 



Fore wing green, with the markings blackish ; basal patch less 

 oblique-edged than in callisthenes, with a rather deep indentation on M, 

 posteriorly much mixed with green ; some dark and whitish costal 

 irroration between this and the median band ; median band constricted 

 in middle, the antemedian line being deeply excurved ; postmedian 

 rather strongly lunulate-dentate ; enclosed area variegated, somewhat 

 mixed with red-brown anteriorly, then with green (including a small 

 black cellmark) ; a black longitudinal mark in posterior half of cell, 

 and between R 2 and B 3 , behind this some white irroration, finally a 

 green admixture at hindmargin ; distal area mostly clear green, but 

 with a variegated (predominantly red-brown) patch at costa and some 

 clear white, dark-edged subterminal dots or dashes in the anterior part 

 (as far as B 3 ) and again near tornus ; apical dash and terminal line as 

 in callisthenes ; fringe rufescent, with dark spots opposite the veins. 

 Hind wing grey, with traces of alternately paler and darker wavy (or 

 somewhat punctiform) lines in outer part; terminal line and fringe 

 paler and less marked in anterior part than posteriorly. 



Both wings beneath more as hind wing above, but with moderately 

 distinct cellspot and postmedian line.
