20. Nacaduba pamela sp. nov. 



Mai.K. — Uppcrside resembles X. pitclohts Feld., hut both wings are broadly 

 bordered with dark brownish grey, the spots on the underside showing indistinctly 

 through (he wings, the snbmarginal rows of the dark spots on the underside being 

 represented on the upperside by sulunargiiial bands. 



Underside: more tawny and paler than in A. 2>«cto?MS, witli the two rows of dark 

 brown spots more separate, especially on the posterior wings; the ])ale liaiids on butb 

 wings are more yellowish white and somewhat broader. 



Female. — Upperside: dark greyish brown. Anterior wings centred by a pah- 

 bluish white space, in which are several dark spots; the lower part of the cell and the 

 space below it to the inner margin is dull greyish blue. On the posterior wings is a 

 row of indistinct black spots before the margin, bordered outwardly by greyish wliilc 



The underside is darker tawny than in the inale. 



Expanse of wings : 1 1 inch. 



Hah. S. Celebes. 



A long series of both sexes. On some of the /ema/fts the pale central space on the 

 upperside is scarcely visible, and in others it is entirely absent. In the figure of 

 N. azureus Kiiber the pale bands on the underside appear to be narrower, and the 

 rows of dark spots towards the margins to be less se}iarate, than in this species, and 

 there is no trace of the broad dark margins on the upperside of both wings of I lie 

 male. 



21. Nacaduba valentina sp. nov. 



Male. — Upperside closely resembles i\. coelia Grose Smith. 



Underside ditfers from that species in being more rufous brown, with the outer- 

 marginal white areas more restricted. 



FEMALE. — Upperside diSers from N. coelia in the shape and .size of the wliite 

 patch on the anterior wings, being in X. valeitlinfi more restricted and less angulated 

 outwardly ; the end of the cell is traversed by a dusky elongate bar, of which there is 

 no trace in N. coelia ; the basal and inner-marginal area of the anterior and tlie basal 

 area of the posterior wings are dull rather violaceous blue, instead of greenish blue as 

 in N. coelia, and on the posterior wings the marginal row of dark lunules is better 

 defined and extends farther towards the apex. 



On the underside the broad white central outwardly angulated band of X. coelia 

 is represented by a much narrower band, which is not outwardly angulated ; there is 

 no marginal white space on either of the wings, and of the three lunules towards the 

 anal angle of the po.sterior wings, the middle lunule is surrounded with rufous except 

 at its base, the two others being partially marked witli colour; in ^V. coelia the two 

 anal lunules only are capjird with yellow. 



Expanse of wings : 1 inch. 



Hab. A long series of taales from Tenimber and Ainboina, and twofeiiiali'si'nww 

 Amhoina. 



If the difference in the females had been less marked, I should have hesitated in 

 separating this species from X. coelia; it is also allied to X. vincida Druce. 



22. Nacaduba rita sp. nov. 



Male. — Upperside: pinkish viulaciHius blue; both wings very narrowly bordered 

 by brownish black, rather more broadly so at the apices. Posterior wiugs with a row 

 of spots on the outer margin, the largest being situate between the lowest median
