first from one-fonrtli of costa cnrved to base of inner margin ; outer line from 

 three-fouvths of costa, dentate-Innnlate, much incurved below middle and joining 

 median sliade at middle of inner margin ; snbmarginal line pale, Innnlate, the 

 Innnles filled in with black forming a distinct line ; marginal spots and cell-spot 

 black. 



Uindivings : with antemedian diffuse darlc shade ; postmedian strongly marked 

 black dentate-lunnlate line, and a black snbmarginal line bent beyond cell ; cell-sj)ot 

 black ; the postmedian line is followed by a distinct broad fnlvons tint. 



Underside dingy whitish grey without speckling ; the cell-spots, outer lines 

 and snbmarginal shade indicated. Head, thorax, and abdomen like wings ; second 

 joint of jialpi blackish, the tips ochrcous. 



Expanse of wings : 46 mm. 



One (? from Yokohama, June 1896. 



The species bears much resemblance to Serraca infixaria Wlk., but it has no 

 series of hairs on the underside of hiudwings along the submedian fold, and the 

 cell-spots are simple, not annular ; a characteristic whicli also distinguishes it from 

 A. ratotaria Swinh. Tiie palpi are laterally flattened and upcurved in front of face; 

 veins 10 and 11 of forewings coincident throughout. 



Didymoctenia gen. nov. 



Distingnished by the antennae of tlie <S which are armed with a pair of closely 

 contiguous fine and long ciliations on each side of each joint, the ciliations them- 

 selves finely ciliated both laterally and apically. In the forewings veins 10 and 11 

 are coincident ; and a fovea is i)resent. The scaling of the underside is smooth and 

 glossy, as in Myrioblephara, to which genus it seems allied. 



Type : D. exmperata "Wlk. (Boarmiu). 



29. Ectropis (?) praepicta sp. nov. 



Forewings : whitish, thickly peppered with fine black atoms ; costal edge 

 finely ochreous ; lines olive-fulvous, marked by black dashes on the veins, and 

 starting from large black costal spots ; first from nearly one-third of costa to 

 one-fifth of inner margin, bent below costa, preceded by a similarly curved and 

 broader fulvous band ; median from two-fifths of costa etnbracing the cell-spot, 

 bent inwards on the median vein, then vertical ; outer line from two-thirds of costa 

 to two-thirds of inner margin, denticulate and outcnrved in middle, followed by a 

 fulvous band ; submarginal line whitish, irregularly lunulate, the lunules filled up 

 with Vilack, that between veins 3 and 4 forming an oblong black blotch reaching 

 outer line ; marginal area fulvous-tinged, except between veins 3 and 4 ; a row of 

 black marginal lunulas ; fringe grey, with a reddish tinge ; the cell-spot consists of 

 raised velvety black scales. 



Hiruhcings: with single antemedian and double postmedian lines ; the lunules 

 of the submarginal filled in with olive-fulvous ; cell-spot small, black. 



Underside blurred cinereous, with the cell-spot and outer lines dark, blackish 

 on the veins ; darker submarginal shades on both wings ; apex of forewings pale ; 

 costa of forewing yellowish with black striae and spots ; fringe white with black 

 base. Head, thorax, and abdomen wliitish dusted with grey, the thorax rather 

 darker ; metathorax with black ring ; face white with a black bar at top and across 

 the middle ; palpi externally blackish, white underneath.
