460 Geometridae from Dutch New Guinea and Mefor Island 



7. Tanaorhinus imipuncta Warr. meforensis subsp. nov. 



$ . 



Smaller than the name-type, fore wing with the median area 

 concolorous or nearly so. Hind wing with the postmedian pale line 

 obsolescent anteriorly, apparently thicker and more dentate than in 

 the other races, rather thick and ill-defined posteriorly. 



Hind wing beneath with the postmedian line weak or almost 

 wanting. 



Mefor, August 15 to September 10, 1920, three $ $ . 



To some extent intermediate between rafflesi Moore and tmipuncta, 

 suggesting that the latter may prove a race of the former. 



8. Dioscore ancyla sp. nov. (pi. XXIV, fig. 9). 

 $ , 39—43 mm. 



Palpus with the third joint quite short, mostly concealed. Antennal 

 pectination short, the longest branches scarcely 3, more than one- 

 half the shaft non-pectinate. Frenulum with the club small. Head 

 and body green, the abdomen posteriorly mixed with white, beneath 

 mixed with white. Hind tibia with hair-pencil moderate, mostly white. 



Fore wing with W stalked ; celandine - green (pi. xlvii, b, in 

 Ridgway), costal edge of fore wing inclining to pea-green, terminal 

 area in distal half pale nile-blue ; a deeper green cell-dot ; a greatly 

 incurved white line from apex to hindmargin at about 3 mm. from 

 tornus, proximally edged with yellowish-green ; fringe yellowish-green. 

 Hind wing rather elongate tornally, distal margin faintly waved, little 

 convex, least so between SC 2 and M 1 ; M' about connate ; concolorous 

 with fore wing, at costal margin paler mixed ; cell-dot minute ; post- 

 median line straight, nearer to termen at abdominal margin than at 

 costa. 



Fore wing beneath with the pea-green shade extended, embracing 

 most of the wing proximal to the postmedian line, only behind M and 

 M 2 remaining pale, at hindmargin almost white ; cell-dot weak ; 

 postmedian line weak, anteriorly almost obsolete, but developing a 

 white apical spot. Hind wing with the line moderately distinct, 

 especially its green element, which curves slightly away from tornus 

 at its posterior end. 



Nomnagihe, 25 miles south of Wangaar, 2,000 feet, January- 

 February, 1921, three $ $ .
