300 On new Ileterocera from Dutch New Guinea. 



just beyoml vein 2 ; base metallic greenish blue as far as the 

 band. Hind wing below as above, but the blue extends 

 farther and leaves a narrower distal margin than above. 



Head, thorax, and abdomen dark blue. 



Sexes simihir, except that the S bears on coxa of fore leg 

 a thick fringe of MJiite hair. 



Length of fore wing, ^ 17, ? 19 mm. 



Types from Angi Lakes. Arfak Mountains, GOOO feet, 

 N. New Guinea, March 1914. A series. 



Buzarn calodesrna httinuirgo, subsp. n. 

 {VI XIL fig. 10.) 



? . Differs from cahdesma, Rotiis., in the extended red at 

 base of costa of fu-e wing nearly filling the basal two-thirds 

 of cell, leaving only a narrow streak of black at its base. 

 The yelli'W band is deeper in colour and nearly straight on 

 its outer edge, and is widened proxinially to just below origin 

 of vein 2. At apex of wing tlie fringe only is yellow. On 

 the hind wing the marginal band is about three times as wide 

 as in calodesma, being 4 mm. broad. Below, the band on 

 fore wing is broader than above. 



Length of fore wing 29 mm. 



Type a ? from Momi River, N. New Guinea, March

Purohusis feVuvt, sp. n. (PI. XII. fig. 11.) 



cJ . Ground-colour of whole insect chrome-yellow, veins 

 and other markings chestnut-brown. 



Upptrsidt'. — Fore wing with only the costa, apical area, 

 and outer margin for a breadth of 4 mm. of the ground- 

 colour, the rest being creamy buff, limited distally by the 

 first of four transverse lines ; the first of these begins at a 

 quarter of costa from apex, curves at vein 7, is straight to 4, 

 and lunulate to inner margin at three-quarters from base ; 

 the second line parallel to first and much thicker, the third as 

 thick and straighter, the space between it and second being 

 twice the width between this and first line ; the fourth line, 

 faint on costa, is marked by a curve in middle of cell, a short 

 bar, more j)roximal, below median of cell, and a straight line, 

 more distal, from 1 c to inner margin, where it joins the 

 second line. Base of cell suffused with chestnut-brown, and 

 a square spot of same colour below it near base. A thick 

 line from base along inner margin and touching fourth line. 

 Interspace between discocellular, third line, and vein 4 

 suffused with chestnut-brown ; the third line joins the second
