New Geometridae from Central Ceram 291 



hedyphaes, the thorax almost without green admixture, the black dorsal 

 spots in abdomen less strong (in the paratype almost obsolete). 



Wings similar to those of hedyphaes, except as noted below. 



Fore wing nowhere clear green, only in the subbasal area, and in a 

 narrow band beyond the median shaded with brownish olive ; basal 

 patch more uniformly mixed with red-brown, less deeply indented at 

 M ; an ill-defined band in the succeeding area ; median band shaped 

 more nearly as in callisthenes but less broad, especially at hindmargin, 

 where it is not, or scarcely, half so broad as at costa ; its colour is less 

 variegated than in hedyphaes, the black longitudinal shade weak; the 

 white defining lines broader ; the white subterminal line continuous, 

 though rather irregular, weakly lunulate-dentate, accompanied proxi- 

 mally and distally by irregular brown shadings, and proximally between 

 the radials by well-developed black spots ; a small white spot at mid- 

 termen ; terminal line broken into sharply-defined pairs of black dots. 

 Hind wing with a pair of fine grey central lines indicated, recalling 

 those of callisthenes ; postmedian lines excurved behind middle. 



Underside rather more heavily dusted than in hedyphaes, at least 

 on hindwing ; postmedian of both wings excurved at or behind middle. 



? . 34—35 mm. 



Slightly darker, median band of fore wing considerably broader.

21. Bordeta posticigutta sp. nov. 



$ . 46 — 47 mm. 



Face and palpus blackish-brown, palpus paler beneath. Antenna 

 with fascicles of cilia slightly over 1. Thorax above blackish, 

 beneath orange-yellow. Abdomen orange-yellow, with narrow black 

 belts posteriorly on the second to fourth tergites and confluent patches 

 on the fifth to seventh, joining an anal one. Femora and tibiae in 

 part (chiefly beneath) orange. 



Fore wing not narrowed, venation not distorted, cell about half, 

 SC 1 ' 2 coincident, connected by a bar with stalk of SC 3 " 4 ; black-brown ; 

 markings white, very slightly sprinkled with pale orange-yellow 

 scales ; a small or moderate, rather oblique patch in cell near its 

 end, posteriorly crossing M, on which, however, it is sometimes dotted 

 with blackish ; a narrower, usually longer patch from C to R 3 or M 1 ,
