 Syntomis -wimberleyi, n. sp. (Plate XLIII. fig. 11.) 



Blackish brown ; spots and markings golden yellow, not gilded ; 

 fore wing with a small spot subbasal, two large spots medial, the 

 lower one the larger, and two discal, the largest of all ; hind wing 

 golden yellow, with a deep costal and marginal band, the latter 

 attenuated to the hinder angle ; front of head, sides of eyes, collar, 

 spots on fore and hind part of thorax, segmental bands of abdomen, 

 all golden yellow ; underside, wings as above, legs marked with 

 golden yellow, and the segmental bands of the abdomen completely 

 encircling it. 



Expanse of wings ly^^ inch. 



Hub. Andaman Islands. One perfect specimen, received from 

 Mr. Wimberley. 



Most nearly allied to <S'. pfeifferi from Sumatra, differs in the 

 pattern of the yellow spots on both wings ; the fore wing having 

 a single spot only before the apex, while the lower outer spot on the 

 posterior margin is narrow and elongated obliquely outwards ; on 

 the hind wing the yellow spot extends through the cell, and is also 

 deeply indented from its outer edge to the median vein. 



NoTioPTERA PROPERTA, n. sp. (Plate XLIII. fig. 6.) 



Deep black ; antennae long, two thirds of the length of the fore 

 wings ; shaft glistening, pectinated from the base to the tips in both 

 sexes, but three times broader in the male than in the female ; fore 

 wings with two bands of white hyaline streaks — first medial, con- 

 sisting of five, the other discal, consisting of four, the lowest one 

 broadest and more rounded. 



Hind wings with a long suffused semihyaline whitish subcostal 

 streak from the base to near the apex, a central short median streak 

 also from the base, and two or three other faint, scarcely visible 

 streaks adjacent, and two discal hyaline spots close together, the lower 

 one much the larger ; thorax and abdomen deep black, with a bluish 

 sheen with bright gilded golden-yellow bands ; but in three perfect 

 examples before me, two males and one female, all taken in the same 

 month, at the same place, these bands all differ ; one male has a 

 broad collar, a large spot in the centre of the thorax, and the two 

 penultimate segments of the abdomen all bright golden, gilded yel- 

 low, with this colour running up some distance on each side ; the 

 female has the thorax-spot absent, and the other male has the 

 thorax-spot and collar both absent, but in all other respects they 

 are identical. 



Underside deep black ; wings as above ; proboscis yellow. 



Expanse of wings 1 j^j inch.
