32. HuPHiNA LADAs (Gr. Smith). 



Delias ladas Grose .Smith, A' or. ZooL. i. p. 585 (1894) (German New Guinea). 



The single o has the basal yellow streak on the underside of the hindwing obsolescent 

 and the apical spots on forewing niiich reduced.

 Guinea). 



AU 3 33 show a red spot on hindwing above vein 6. The 2 ?$ on the upperside are 

 very yellow. Fruhstorfer hints at ornytion Salv. and euryxantha Honr. being sub- 

 species of this insect, but this is disproved by euryxantha and this form occurring 

 together.

35. Appias celestixa (Boisd.) 



PicHs cclcslina Boisduval, Voy. Aslr., Lep.. p. 46, No. ] (1832) (Dorey). 



Herr Fruhstorfer divides up this insect into 8 subspecies, of which he attributes 

 celestina sekarensis to S. and W. Dutch New Guinea. Ribbe's description of his 

 sekarensis is absolutely different from the 12 specimens of the Wollaston expedition. 

 I cannot separate these latter from celestina at present, for while some, it is true, show 

 no signs of the submarginal band or spots, others show the same distinctly ; and as 

 there are no ??, in which latter sex the differences in the local races are truly defined, 

 it is better to treat these specimens as celestina*

* So far no race of A. celestina is recorded east of the Bismarck Archipelago, but I have a single speci- 

 men from Bougainville, Solomon Islands, which I now describe here as a 2iew race of A. celestina. thouuh 

 it will probably prove to be an entirely new species. 



Appias celestina orientalis subsp. nov. 



3. Differs from the other forms of celestina in its larger size and very strongly arched costa. Above 

 it differs in the forewings being entirely blue and in the hindwings having a narrow brown border ; the 

 blue on both fore- and hindwings has a decided yellowish tinge. Below it differs from all the forms of 

 celestina in being yellow washed with olive and having a broad, curved, sooty submarginal band to both 

 wings. The forewings have also below a bluish wasli. 



Expanse 88 mm. Length of forewing 42 mm. 



Hab. Arawa, Bougainville, Solomon Islands, Dec. 1907 (A. S. Meek).
