Sysstema gen. nov. 



Forciriiif/x : ainjile, triangnlar ; costa noarly straiglit, convex at. apex : apex 

 ronnded ; hindmargiu oblir^neh' curved. 



llinihriiu/s : ronnd, with ronnded liindinargin and rather prominent anal angle. 



Antennae of <S bipectinated to tlirec-fonrths, the branches long ; palpi porrect, 

 hairy, terminal joint short and liardly visible ; tongne and frennlnin present ; 

 no fovea. 



yrnrafinn : forewings, cell half as long as wing ; discocellnlar vertical ; tirst 

 median nervule at two-thirds, second and third from end of cell ; radials normal : 

 7, 8, 9 stalked; 10 and 11 coincident. Hind wings with costal approximated to 

 subcostal for nearly one-half cell ; and 7 from end of cell ; 3 close before 

 lower end. 



Type : S. seniieiirHktta Moore (Ei/pifhec/a). 



In this genus I include also deiitilinea '\\a,rT.,al6ibasisllini)s,n.,concinna Warr., 

 and ulhipieta Warr., placed together in one subsection by Hampson, and said to 

 have vein lii of forewings stalked with 7, >*, 9; but this I do not find to be the 

 case in the examples I have seen. 



Subfamily SEMIOTHISINAE. 



137. Acadra ancillata sp. nov. 



Foreu'iiH/.-i : whitish, dusted with olive-ochreous and fuscous, and with greyish 

 suffusion in places ; the lines dark brown, oblique ontwards from costa, bluntly 

 angled below it and oblique to inner margin ; first from costa at one-fifth to near 

 base of inner margin ; second from middle of costa to one-third of inner margin ; 

 third from two-thirds of costa to middle of inner margin, broad and straight, the 

 first and second being tine and waved ; followed closely by a darker, more diffuse 

 shade, which runs to hindmargin below apex ; snbmarginal line indistinct, indicated 

 by a brown costal spot; a small pale spot beyond the angle of third line ; each of 

 the three lines is accompanied on the inner side by an obscure grey shade or line ; 

 a marginal row of dark brown dashes ; fringe pale, chequered with brown ; cell-spot

Hind wings: with straight dark brown antemedian line, preceded by an olive-

Underside white, coarsely speckled with dark brown ; a dark brown central

 and veins yellowish. In the $ the postmedian line of hindwings is preceded and 

 followed beyond the cell by spots of black scales. Head, thorax, and abdomen 

 whitish, varied with greyish ochreous. 



Expanse of wings : 30 mm. 



A pair from Goodenough Island, December 1896 (Meek).

Forewings : whitish ochreous, thickly and rather coarsely speckled with fuscous; 

 first line from a brown costal blotch at nearly one-fonrth, bent in cell, then oblique
