New Geometridae and Dioptidae in Joicey Collection 263 



series in coll. Tring Mus. merely labelled " Japan." Probably not 

 uncommon but overlooked on account of its close superficial 

 resemblance to minute biselata or invalida. The only hitherto known 

 Japanese species of the section Xenocentris is effuvaria Christ. 



Subfamily Laeentiinae.

 closely lamellate, pubescent. Legs mostly darkened, extremities of 

 joints white. 



Fore wing rather elongate, costa arched posteriorly, apex moderately 

 sharp, termen slightly curved, oblique; E 1 connate or just separate; 

 glossy ; basal patch and median band black-brown with a slight vinous 

 admixture, margined by white lines ; the subbasal white line excurved 

 in middle, slightly indented at SM 2 ; succeeding area white, transversed 

 by three irregular, incomplete, in places confluent lines which arise from 

 two black-brown costal spots, the first line remaining black-brown, the 

 other two mostly vinous, with slight dark irroration ; antemedian line 

 at about one-third with a small proximal projection at M and strongly 

 oblique inward from fold to SM J ; celldot moderately large, black, 

 surrounded or followed distally by some pale scaling ; postmedian at or 

 beyond two-thirds (median area variable in breadth), very acutely pro- 

 duced on R, 3 , strongly incurved or inbent behind, the band consequently 

 much constricted behind M 2 ; area beyond postmedian white, trans- 

 versed by two lines analogous to those preceding the antemedian, but 

 with the distal the darker ; distal area mostly dark-coloured, especially 

 proximally to the subterminal, which is slender, slightly interrupted, 

 cut by a conspicuous oblique white posteriorly dark-edged streak from

 line broken into short dashes ; fringe weakly chequered, and with a 

 whitish line at base. Hind wing elongate costally, termen slightly 

 vinous ; pale, with a fleshy or vinous tinge, the markings of underside 

 feebly indicated. Fore wing beneath more suffusedly marked than
