462 Geometridae from Dutch New Guinea and Mefor Island 



10. Anisozyga polyglena sp. nov. (pi. XXIV, fig. 6). 



$ , 36 mm. 



Face white, the upper half soiled with red-brown. Vertex white 

 with some brown and black scales. Palpus brown, beneath white, on 

 outer side (except third joint) with a black stripe. Antennal pectina- 

 tion short (little over 1). Thorax and abdomen white, the tegulae, 

 patagia and anterior segments of abdomen spotted with green, the 

 posterior segments with black. Legs mostly white. Pectoral hair- 

 pencil white. 



Fore wing with termen scarcely waved, venation normal, E 1 about 

 connate; rainette-green (Eidgway, pi. xxxi, i), with fine white irrora- 

 tion and strigulation ; cell-mark white; costa to 3 or 4 mm. broadly 

 whitish with heavy admixture of black, then more narrowly whitish, 

 less dark-mixed, distally pale-brownish with a little dark irroration ; 

 lines white; antemedian at about 5 mm., rather irregular, thickened 

 at both ends, proximally accompanied at hindmargin by a brown-black 

 patch ; postmedian at nearly two-thirds, mostly slender and rather weak, 

 but irregular, dentate outward on the medians, thickened into a large 

 white spot at hindmargin ; subterminal nearly 2 mm. from termen, 

 connected therewith along most of the veins ; some large conspicuous 

 purple-black (through the lens brown-black, irregularly irrorated with 

 violet-whitish) spots in distal area, namely one at costa (followed by 

 a small one nearer the apex) and one at hindmargin proximal to the 

 subterminal (the latter reaching the postmedian) and two distal to it 

 between E 3 and M 2 ; fringe pale, tinged with green proximally, with 

 brown distally. 



Hind wing with termen moderately dentate ; venation normal ; cell- 

 mark small and weak, dark-green ; antemedian only expressed by the 

 inner marginal spot ; postmedian fairly strong, central ; deeply inbent 

 between E 2 and E 3 ; subterminal partly obsolete; no black spots 

 proximally or at abdominal margin, the distal ones between E 3 and M 2 

 as on fore wing, the apical ones more numerous, more irregular, forming 

 a constellation of four large and some smaller (partly confluent) on 

 a large white apical patch. 



Underside white-green, with the white markings indistinct, the 

 black ones mostly strong, the apical on hind wing enlarged into a patch, 

 the median ones on the same wing also enlarged, also confluent.
