Underside as male. The black marginal s^jots of the hind wing 

 are seen through to the upper surface in both sexes, but are more 

 noticeable in the female. The bases of both wings on upperside in 

 female are slightly dusted with bluish scales.

C dilectissima should be distinguished by its narrow black apex, 

 by the absence of the white disc on the fore wing on its upper- 

 side, and by the distinct rows of black spots on the margins and 

 the generally larger markings below. It is also allied to the 

 recently described 0. ceyx, de NiceviUe, from Java \ 



Ctanieis pfspa.

I have seen one specimen only of this species from Borneo, a 

 male, which was identified by Mr. Herbert Druce as 0. cagaya, 

 Eeld., and is now in Messrs. Godman and Salviu's collection. 

 This specimen is identical with one from Malacca, also in these 

 gentlemen's possession, marked " C. lamhi " by Mr. Distant. I do 

 not know how C. cayaya can be distinguished from 0. puspa. 

 The broad-bordered and the narrow-bordered forms occur together 

 in the Philippine Islands, both with and ■without white discs. 

 What I take to be the typical C cagaya is the broad-bordered 

 form of the ' Novara ' Voyage, and which now stands in the Felder 

 collection marked " lalage" which appears to have been affixed to 

 it in error, as I could find no specimen marked " cagaya." 



Ctaniris placidula, sp. n. (Plate XXXII. figs. 6 c?, 7 $ .) 



(S . Closely allied to G. plackla, de Nicev. Upperside darker 

 blue, with the outer margins more broadly black and less sharply 

 defined inwardly ; costal margin of hind wing much more broadly 

 black. Underside differs from C. placida by the discal band of 

 spots in the fore wing being more in line and, towards the outer 

 angle, reaching close to the submarginal line. The submarginal 

 lines in both wings are composed of less distinctly crescent-shaped 

 striae than in C piJadda. 



$ . Upperside broadly black-bordered, bluish on the discs, both 

 wings with a black mark closing the cell ; fore wing with a whitish 

 blotch beyond the end of the cell ; hind wing with a marginal row 

 of lunules enclosing black marginal spots. Underside as male. 



Expanse, S II^Ittt' 2 ^\ inch.

Apparently plentiful where it occurs. There seems to be prac- 

 tically no variation, judging from the specimens I have examined.
