tallies precisely with one of the aberrations received from Kiriwini, Trohriand Islands. 

 In view of the wonderful variability shown by these examples, I have thought it. well 

 to give a brief description of the four principal aberrations, premising that Meyrick's 

 type-form is pale ochreous, with fuscous irrorations. 



ab. fasciata ab. nov. 



S. Ground-colour as in type-form ; a broad blackish fascia occupying the space 

 between median and postmedian lines of forewings, and extending somewhat beyond 

 the latter ; in the hindwings forming a still broader blackish central fascia ; basal 

 line of forewings and submarginal line of both wings strongly marked with blackish; 

 in the forewings opposite the cell two black streaks connect the submarginal line with 

 the hindmargin ; abdomen with blackish band corresponding to the band of hindwings. 

 In several of the whiter forms, otherwise agreeing with Meyrick's description, the 

 hindwings have a distinct greyish or fuscous central fascia, but the dark markings in 

 general are not so pronounced as in the aberration /M6ci«i«. 



ab. semialba ab. nov. 



c?. Forewinfjs : entirely suffused with blackish fuscous, e.xcept a blotch at apex 

 and on middle of hindmargin, and a semicircular space from base of costa to inner 

 margin beyond middle, which are pale with fuscous specklings ; submarginal line only 

 distinct and edged with ]ialer. 



Himhvinc/s : witli only the apical region blackish; the lines only clouded with 

 lilack. 



One S from Fergusson Island. 



ab. rufigl'isea ab. nov. 



¥. F(yreu!ings : wholly dull grey, with a reddish tinge, the veins dusted ochreous 

 and fuscous ; space between first line and median shade whitish ; cell-spot prominent, 

 (lull grey, with whitish scales in centre ; a dark fuscous submarginal blotch below apex. 



Hindwiiiijs : the same, but the whole basal third white; fringes of both wings 

 whitish. 



One ? from Kiriwini, Troliriand Islands. 



ab. suffusa ab. nov. 



¥. Forewings: wholly sufl'used with dark reddish grey; a yellowish jiatch at 

 liase ; the first line preceded and the second followed by an irregular Iiand of yellowish 

 and blackish .scales, the vein.s being yellow towards hindmargin. 



Ulndivings: the same; fringes of botii wings dull grey. 



Abdomen grey ; thorax and head whitish gre}'. 



One 5 from Kiriwini, Trobriand Islands. 



This aberration, except in point of size, answers well to the description of 

 Meyrick's 5 callicrossa ; hut nearly all the examples under consideration are from 

 48 to 50 nmi. in expanse. 



The undersides nf all the above forms agree, being pale or dull smoky cinereous, 

 with large black cell-spots and blackish submarginal shade, leaving apex and spot 

 in middle of hindmargin of forewings and the whole hindmargin of hindwings paler. 

 The pale shades are, as a rule, more developed in the ? than in the <S.
