69. Xanthomima partita sp. nov. 



Fornri Ill/a : l)lack, with three bright yellow lilotches ; <a narrow one on inner 

 margin from near base to beyond middle, broadening outwards ; an irregular 

 trapezoidal one, nearly or (|uite touching costa beyond the black basal patch, 

 separated by an obli(|ne black central bar from the transverse elongated third, 

 which has its outside edge curved, its lower end blunt-jwinted and its upper end 

 flat, stopj)ing short at the subcostal vein in the i and continued close to costa 

 in the ? . 



Ilindicimjs : yellow, with hindmargin uniformly broadly and costal edge 

 narrowly black ; a straight, thick, black bar from jnst above anal angle to costa, 

 median in the ? , slightly postmedian in the c? ; base of wing narrowly black. 



Underside exactly similar. Abdomen and base of patagia j'ellow ; head, 

 thorax, and rest of patagia black ; pectns and legs dull black. 



Expanse of wings : S, 4s mm. ; ? , 52 mm. 



Four SSi two ?? from Gnailalcanar, Solomon Islands, April — May I'.tOi 

 (Meek). 



In the ? ? the black horizontal bar above inner margin, which in the SS is of 

 uniform thickness, is much attenuated outwardly, and the yellow blotches on each 

 side are proportionally enlarged ; in one cJ the u|iper blotch is narrow and flattened, 

 the costal margin being broadly black. 



In A', disrupta Warr. from Alu, to which it is closely allied, the black hind- 

 marginal border is traversed by an interrupted yellow streak, and the trapezoidal 

 blotch is ])ear-shaped, being continued to middle of base ; all the black markings 

 are much narrower, and the yellow more largely developed. 



Subfamily BISTONINAE. 

 7(J. Phthonandria confusa sp. uov. 



Foreicings : ochreons grey, covered with dark atoms and striae ; costa strigulated 

 with blackish, and with blackish spots at the origin of the lines, which are very 

 obscure ; a curved inner line at one-fifth ; an' outer line at two-thirds of costa, bent 

 at vein (i, then oblique to middle of inner margin, where it nearly touches a dark 

 median shade passing over the blackish cell-spot ; an indistinct waved submarginal 

 line ; fringe concolorous, with slight blackish spots between the veins at their base. 



Hindwings : with thick antemedian shade, continuing the median of forewings, 

 and obscure jwstmedian and submarginal lines or shades. 



Underside paler, without lines ; the cell-spots and costal markings alone distinct. 

 Head, thorax, and abdomen speckled grey, the abdomen somewhat darker. 



Ex])anse of wings : .56 mm. 



One ? from ( 'hitral. 



The species is jilaced in I'hlhonaiidria ju-ovisionally : at first sight it would 

 appear to belong to the Scotopteri/ginae ; but the forehead is flat, the tongue 

 altogether absent, and the antennae (?) bipectinated, the pectinations stiff and 

 short, ending in a short bristle. The hindmargins of both wings are slightly 

 crenulate, and the nenration normal; veins lU and 11 of forewings coincident.
