of abdomen, being yellow. The yellow border of hiudwing above is more than 

 half filled up along the margin with elongated lunulate blotches of black between 

 the black veins, which on the underside are much reduced, and form only spots 

 iu the anal half of wing ; the inner margin of hiudwing, like its base, is whitish 

 bine, not yellow, as in aurilimbata. The hiudmargin of hiudwing is bluntly but 

 decidedly angled at middle. In the forewiug the lowest dark purple basal streak 

 runs up to submcdian fold, where it touches the extremity of the oblique streak 

 from costa, and then curves down and joins the lowest blotch of the snbmarginal 

 fascia before anal angle ; all the purple markings of forewing, as in aiirilimbatu, 

 are broad and well developed. 



Expanse of wings : 82 mm.

S. Dysphania deflavata spec. nov. 



This Sumatran insect diti'ers from all the forms referred to maldi/dnua Guer. 

 and its allies by the entire absence of yellow scaling on the wings, both above 

 and below, except a small patch on the underside of hiudwing above anal angle, 

 the yellow of the pectus, femora, and underside of abdomen being likewise reduced. 

 The hiudmargin of hindwing is, as in the last species, bluntly elbowed at middle ; 

 the sinuous postmedian dark fascia is much narrower, in the hindwing, iu 

 particular, being reduced to a mere sinuous belt. In the forewing the pnrple line 

 from base of inner margin is faint, and joins on vein 2 the oblique line from 

 costa, but there is no dark line from base either along costa or median vein ; 

 neither is there any dark purple line at the extreme base of hindwing. The 

 abdomen is dull cream-colour, with faint brownish belts, the anal segment 

 brownish yellow. 



Expanse of wings : 78 mm.

Generally speaking, Sumatran forms appear to dilFer intrinsically from those 

 of other islands.

 9. Metallochlora circumscripta spec. nov. 



Forewmy : apple-green ; costa flesh-coloured ochreous, with a few minute 

 black specks ; an obscure paler green snbmarginal line, apparently curved inwards 

 towards costa, and traces of a curved inner line ; cell-spot ferruginous, with black 

 scales at middle ; a pale whitish yellow ribbon-like marginal band ; the margin 

 with slight lunular marks of dark brown scales between veins ; fringe pale 

 flesh-colour. 



Hindwing : similar. 



Underside paler green, with the pale marginal line showing through ; forewiug 

 with costa ochreous, speckled with black, and a small brownish blotch at apex. 



Face and palpi externally red-brown ; vertex dull greenish ; thorax and base 

 of abdomen green ; rest of abdomen yellowish green, the dorsum with five metallic 

 bronzy red-brown plates.
