NEW FORMS OF BUTTERFLIES FROM THE SULA IS., 

 AND THE ISLANDS OF OBI, ARU, AND TENIMBER. 



By J. J. JOICEY and G. TALBOT. 



PIEEIDAE. 



1. Elodina aruensis sp. nov. 



We cannot assign this form to any known species at present, but 

 it must certainly be a race of one of the similar New Guinea or 

 Moluccan species. It much resembles namatia Fruh., from Waigeu. 

 8 . Upperside chalky-white. Fore wing with black-brown distal 

 area as in namatia, but only reaching vein 2 ; inner edge as in namatia, 

 but the tooth on vein 4 is less produced, the edge between 4 and 6 

 being more oblique. Basal dark area narrower than in namatia. 



Underside of fore wing with smaller dark subapical band, not 

 reaching" vein 3, and fading out on the costa. Basal yellow suffusion 

 as in namatia. Hind wing with basal half of costa pale yellow, more 

 marked than in namatia. 



Length of fore wing : 24 mm. 



Aru Islands, March to May, W. J. C. Frost, two 8 8 . 



2. Elodina egnatia Godt. tenimberensis subsp. nov. 



Close to the race angulipemiis Luc. from Australia. 



8 . Fore wing with the marginal brown reaching nearer the tornus 

 than in angulipennis. The tooth on vein 4 is much less pronounced, 

 but is sharply angled, and the edge of the apical area is more oblique 

 from vein 3 to costa. 



Underside of fore wing with larger and paler brown subapical 

 patch, somewhat quadrate and with a narrow prolongation to vein 3. 

 Base with only a slight yellow suffusion. Hind wing with costa pale- 

 yellow on basal two-thirds, no trace of postdiscal markings, and a 

 yellowish tinge on the submedian area. 



Length of fore wing : 18 mm.
