466 Geometridae from Dutch New Guinea and Mefor Island 



December, 1920 (five 3 3), December, 1920 to January, 1921 (type and 

 two other 3 3 , allotype ? ). 



Differs from vestigiata, apart from the lines, in the rather longer 

 palpus, absence of white dorsal dots of abdomen, larger size and perhaps 

 slightly brighter colouring; from sororcula Warr., and fraterna Warr., 

 in the palpus, the dotted lines, the fringes, etc. Occurs also with 

 vestigiata at Mount Goliath : one 3 and two ? ? had been put aside 

 at the Tring Museum for investigation. 



17. Prasinocyma pratti sp. nov. (pi. XXIV, fig. 4). 

 3 , 38—39 mm. 



Face slightly loose-scaled, green. Palpus If, third joint nearly half 

 second oint ; ochreous, mixed (especially proximally) with green. 

 Antenna ochreous. Vertex and occiput green. Thorax above green, 

 beneath white, in front of fore coxa green. Fore leg above largely 

 black-grey, pale at extremities of joints ; hind leg whitish-ochreous, the 

 tibia only moderately dilated, the hair-pencil rather slender. Abdomen 

 above green, beneath white ; each segment with a triangular ochreous 

 dorsal spot, its apex directed forward, its anterior part, finely dark- 

 edged, its posterior becoming whiter. 



Fore wing with apex acute, termen subcrenulate, SC 1 free, M 1 

 almost connate ; green ; costal edge deep ochreous, dotted with blackish ; 

 cell-dot deep-green; lines pale-ochreous ; antemedian 4 mm. from base, 

 deeply lunulate outward in cell, in submedian area, and behind SM 2 , 

 thickest at ends of the lunules ; postmedian zigzag, from SC 5 about 

 3 mm. from termen to hind margin about 4 mm. from tornus, obsolete 

 between a spot on SC° and one on R 1 , thence with the outward teeth on 

 the veins, a deep inward curve between M 2 and SM 2 ; fringe ochreous, 

 deeper proximally than distally and with black-brown dots at ends of 

 veins and of submedian fold. Hind wing with termen crenulate, slightly 

 angled at E 3 ; SC 2 very shortly stalked, M 1 about connate : nearly as 

 fore wing except costally, but with antemedial line wanting. 



Underside whitish green, unmarked ; costa of fore wing and fringes 

 as above. 



Mount Kunupi, Menoo Valley, Weyland Mountains, 6,000 feet, 

 December, 1920 to January, 1921, two 3 3 . 



A rather anomalous species, with somewhat the facies of a Dioscore.
