black blotches, which may Ijccome confluent aud more or less reproduced ou the 

 Ibrewiugs as well. The trausverse darker striae are at times (|uitc absent, while in 

 other cases they darken the whole of the wiugs. In a few instances a dark basal 

 streak runs along the subcostal and is more or less forked in tlie cell. In two 

 examjiles the ground-colour is ditfercnt, being a mixture of pinkish grey, reddish 

 fulvous and olive brown. The hiudmargin of forcwings in the J is bluntly bent at 

 vein 7, then straight to anal angle ; in the ? strongly gibbous throughout ; the 

 single ? has the ground-colour yellow. 



21. Dirades albilinea sp. nov. 



Porewings : dull brownish grey, with numerous minute dark dots and striae ; 

 costa dotted, ochreous and fuscous ; a dark grey snflusion on inner margin deeper 

 towards anal angle, before which on inner margin is a blackish blotch, externally 

 white-edged ; a snbmargiual row of minute black dots with white scales internally; 

 fringe iron-grey. 



Hind wings : browner ; the basal area speckled with whitish ochreous aud 

 brownish, and edged by a conspicuous sinuous white line from one-third of costa to 

 two thirds of inner margin; marginal area be^-ond the line olive-brown, towards anal 

 angle dark grey; an indistinct submarginal line of dark purplish lunulcs from upper 

 tooth to anal angle. 



Underside pale dull grey, with fine striations ; hindwings lighter. Face and 

 palpi dark brown. Thorax and abdomen pale ochreous grey ; vertex and shaft of 

 antennae white. 



Expanse of wings : Is mm. 



One t? from Milne Bay, British New Guinea, January 1899 (A. S. Meek). 



Though a, Birades in nenration, this species presents several points of difference: 

 though an undoubted cj, the submedian fold of hindwings is coloured and scaled 

 like the rest of the wing, and bears no tuft of hair whatever. The apex of furewings 

 is truncate from vein S to 7, the hiudmargin between veins and 7 being slightly 

 prominent, thence sinuous to anal angle ; the inner margin has a strong incision 

 beyond middle, and the anal angle is deeply lobed ; hindwing with small teeth at 

 veins 4 and 7 ; the antennae have short close clavate teeth. 



22. Dirades erectinota sp. nov. 



Like conifera Moore, but greyer, with the dark chocolate mark on inner margin 

 more pointed and recurved at its apex which reaches vein 2. The tufts of hair in 

 the furrow of hindwings silky ochreous. 



Two c?c?, one ? , from Iton Island, July 18!.I7 (Doherty) ; one ¥ from Dorei, 

 June 1S97 (Doherty). 



23. Dirades vespertilio sp. nov. 



Forewing&: dull brown, becoming dark grey towards costa ; first line at one- 

 third, curved below costa, second at two-thirds, parallel to hiudmargin, aud partially 

 double ; tlie included space, as well as the base, much clouded with blackish, 

 especially along the costa ; outer line with a pale edging ; apical area whitish grey, 

 with black speckles and a black costal spot ; fringe iron-grey ; the hiudmargin very 

 narrowly dark brown, with an obscure row of dark marks ou its iimer edge.
