Does not differ from Indian specimens excepting in the slightly 

 whiter tint of the under surface.

Does not differ from Indian specimens excepting in its slightly 

 inferior expanse of wing ; in colouring and pattern it perfectly 

 agrees.

Most nearly allied to D. vishnu of Moore from Java (with which 

 species it was associated by Wallace). It differs in its superior size, 

 the narrower black area of the upper surface, the deeply sinuated 

 inner edge of the black area on the primaries, the apical series of 

 spots much smaller, the fifth, as Boisduval says, " tres petite et 

 pouctiforme," whereas in D. vishnu this is the case with a sixth spot 

 not present in D. timoreyisis : primaries below with the basal pale 

 area cuneiform (not angular), pure lemon-yellow within and just 

 below the cell, otherwise pearl-white (" la base gris-blanchatre sau- 

 poudree de jaune pur," Boisd.) : secondaries with only the basi- 

 abdominal third ^ brilliant golden yellow, suffused at its inferior ex- 

 tremity with bright orange ; the inner edge of this area straight, not 

 angulated as in D. vishnu ; the submarginal red lunules narrower, of 

 a more carmine tint, the terminal one not expanded, further from the 

 outer margin, yet not touching the yellow area ; there are in fact, as 

 Boisduval says, " sept lunules," and not six lunules and two spots as 

 in D. vishnu. 



9. Terias maroensis, sp. n. (Plate XXXVIII. fig. 2.) 



2 . Nearly allied to T. excavata of Moore, from India, but of a 

 decidedly deeper yellow (bright sulphur) than the female of that 

 species ; the inner edge of the external border decidedly arched, 

 convex, not concave, towards the costa, the sinuation upon the median 

 interspaces not so deep and more oblique (as in T. sari) ; the discal 



' The carelessness of Boisduval's description at this point probably misled 

 Wallace ; he says : — " La moitie anterieure d'unbeau jaune de chrome." On the 

 other hand, the yellow of D. vishnu has a decidedly dull creamy appearance.
