470 Geometridae from Dutch New Guinea and Mefor Island 



submedian fold or at tornus, in the former- case with a thread-like 

 marginal continuation to tornus ; fringe black, shot with blue. Hind 

 wing black, basally and posteriorly with blue reflections, which are 

 less vivid but more diffused than those of diva Roths. ; fringe less 

 black, with slight blue reflections. 



Underside nearly the same ; hindmargin of fore wing paler — more 

 greyish or brownish proximally, then more yellow; hind wing with a 

 short metallic-blue costal streak at base. 



Weyland Mountains : 5,000 feet, June, 1920, one ? ; Mount 

 Kunupi, 6,000 feet, November, 1920, one ? ; November-December, 

 1920, two $ <? , one 2 ; December, 1920 to January, 1921, three $ $ , 

 three ? ? , including the holotype 8 , and allotype ? ; Menoo River, 

 3,500-5,000 feet, December, 1920 to January, 1921, five $ $. 



Distinguished at once from diva by the much shorter antennal 

 ciliation, as well as by the less broad black apical region ; from rubra 

 not only by the tone but also by the form of the black apical region, 

 which does not, as in that species, run basewards along the costa. A 

 short series from the Wandammen Mountains also collected by the 

 Pratts, has hitherto been mixed in Mr. Joicey's series of rubra, which 

 is at present only known from the Angi Lakes. 



23. Milionia semirutila sp. nov. (pi. XXIII, fig. 6). 

 ? , 38 mm. 



Eye not hairy. Head and body black, the abdomen more greyish, 

 especially beneath and posteriorly, towards the extremity mixed with 

 a few dull orange scales. 



Fore wing not greatly elongate, costal margin gently curved, termen 

 scarcely oblique anteriorly ; cell not quite one-half ; black with a broad 

 oblique orange-red band, occupying about one-third of costa (scarcely 

 proximal to the centre), of uniform width throughout, reaching ab- 

 dominal margin but separated from termen (from M 2 to tornus) by 

 a black thread ; fringe black. Hind wing black, with a slightly less 

 broad orange-red submarginal band, separated from termen by a very 

 narrow black border, which is broadest at about SC 5 to R 3 but tapers to 

 a point at tornus ; fringe black. 



Underside the same. 



Weyland Mountains, Dewaro Village, 3,500 feet, June, 1920. 



Perhaps in some measure transitional to the genus (or section ?) 

 Automolodes Warr., but with the hind wing quite differently shaped.
