3. Sypna nocturna spec. nov. 



Differs from S. tenebrosa Wlk. ia beiug deep dark brown with a purplish 

 tinge and traversed by wavy purplish lines ; the snbmarginal line thicker and 

 blacker thronghont; reniform stigma slightly marked with ochreous ; outer line 

 donblo, regularly lunulate, distinct throughout ; snbtermiual spots black dotted 

 ■with pale. 



Ilimlwing : deep brown to base, the costa alone paler ; the lines obscured ; the 

 pale yellow mottling of the fringe in apical half more strildng. 



Head, thorax, and abdomen dark brown. 



Underside as in tenebrosa. 



Expanse of wings : 65 mm. 



4 (?(?, 3 ? ? from Kinabalu, N. Borneo (Waterstradt) (type) ; 1 S from the 

 Penrisen Mts., Sarawak, June 1892 (Everett); 1 ? from Pengalengan, Preanger, 

 Java. From Gunung Ijau, Perak, a bine-scaled form has been received — ab. 

 decorata ab. nov. — in which not only the inner and outer edges of the antemedian 

 band, but the band itself, except along costa and inner margin, are suffused with 

 bluish scales ; but there is no blue visible in the hindwing, nor along the rows of 

 snbterminal spots, though these are externally much yellower and more distinct 

 than in the type form. 



4. Perigramma triangulifera spec. nov. 



Forewing : ochreous grey, dusted with darker ; inner line pale, edged on both 

 sides with dark, waved and more oblifjue outwards than that of circumducta Led., 

 to which it is most nearly allied ; stigmata grey-white ; the orbicular wider, especially 

 above, both sides ontcurved, not oblique ; reniform smaller, not projecting below 

 vein 4 ; a black triangle in cell before the orbicular, and a dark hourglass-shaped 

 blotch between the two stigmata ; the pale blotch below the white median vein 

 reduced to a very shallow semi-elliptical mark ; a black triangle with the apex 

 touching vein 1 below submediau fold at base ; the fold and space above it at 

 base white ; outer line very indistinct ; the median area only slightly blackish, 

 not well defined between the two lines, as in circumducta ; subterminal line pale, 

 inwardly edged with blackish at costa and beyond cell. 



lUndwimj : grey with diffuse dark grey cellspot and obscurely marked 

 subterminal shade. 



Head, thorax, and abdomen grey, the face and vertex browner. 



1 t? from Tjutju-ho, 400 kilometres north of Wladiwostock, 1009 (W. Man) ; 

 somewhat wasted and with the fringes worn ; sent along with a typical i of 

 circumducta ; in the new sjiecies the basal and costal areas of forewing are both 

 much paler. 



5. Sideridis sericea spec. nov. 



Forewing: silky pale greyish ochreous, slightly tinged with pale brown; the 

 veins pale ; the costal streak pale ochreous thinning to a point at apex ; a black 

 snbbasal costal dot and one at base of cell; inner line obliijue from costa to sub- 

 median fold, then inwardly oblicjue, marked by a black dot on costa, in cell, and 

 on the fold, and one on vein 1 nearer base ; outer line excurved beyond cell, marked 

 by black dots on veins, which are really the teeth of a lunulate-dentate line; 

 black terminal dots between the veins ; a fine white dash at end of mediaa
