280 New Geometridae from Central Ceram 



Probably nearest to albimacula Warr., from Obi, but very distinct, 

 curiously recalling the totally unrelated Hyposidra albifurcata Warr. 

 (Nov. Zool. iv, 119), from the Philippines. 



2. Pingasa porphyrochrostes sp. no v. 



$ . 48 — 50 mm. ; 53 — 56 mm. 



Face ochreous-browu, above very slightly darker and more reddish 

 than below, but without any indication of the blackish transverse band 

 of lariaria. Palpus nearly as in lariaria, in the ? with the third joint 

 rather larger. Head and body whitish, the collar and forecoxa tinged 

 with brown, the abdominal crests mixed with brown on their sides. 

 Legs largely brownish or infuscated. 



Fore wing shaped as in lariaria or with termen very slightly less 

 oblique ; coloration nearly as in lariaria, but with the irroration less 

 coarse, particularly in the proximal and median areas, where they appear 

 more whitish ; antemedian line nearly as in lariaria ; cellmark rather 

 smaller and less angular, in the ? usually quite weak ; postmedian 

 with corresponding distinctions. 



Fore wing beneath in the $ very strongly, in the 2 very faintly 

 suffused with orange (posteriorly more pinkish), from base to cellmark, 

 which is here stronger than above ; a very broad distal border, shaped 

 as in lariaria or slightly more sinuous-edged proximally, but very 

 strongly suffused with purple in the $ , and with slight purple reflections 

 in the ? . Hind wing in the $ with well-developed black cellspot, in 

 the ? with slight or moderate indications of the same, occasionally 

 fairly strong where the discocellulars meet the cellfold ; $ with proximal 

 orange shade as in lariaria, ? with only very feeble suffusions to dis- 

 tinguish it from that of chlora; distal border in $ as purple as that of 

 fore wing, in ? sometimes almost without purple reflections. 



Manusela, 6,000 feet, October to December, 1919, 3 $ $ , 7 ? ? . 



The ? might easily be passed over for slightly aberrant chlora except 

 for the lack of black frontal band, but the $ underside is totally dif- 

 ferent. I suspect it may be a race of manilensis Prout (Nov. Zool. xxiii, 

 193) provisionally described (overlooking the coloration of the face) as 

 a race of lariaria. The large size, less irrorate upperside and distinc- 

 tively coloured underside, however, prevent my definitely associating 

 porphyrochrostes with manilensis at present. The colouring of the 

 upperside readily distinguishes the 2 from another similar species, 

 subpurpurea Warr.
