not see or hear of the Evploea in the Cook group. 1 saw 

 D. archippus in Aitutaki only. The little blue C. cnejus (or 

 form) was present in all the Cooks but not in Tahiti. I did 

 not meet M. leda in the Cooks, but it was present in Tahiti. 

 The Atella was present in Earotonga and Manjaia, but I did 

 not see it elsewhere. 



" The Tahitians are all wretched specimens, but I saw no 

 decent Euploeas and, so far as H. bolina is concerned, although 

 I saw hundreds of (^, I only saw four or five $ in Tahiti, 

 and all resembled the (^. The form from Earotonga is very 

 distinct, being larger and always with the buff apex to the 

 fore-wings, although often variable in the rest of the pattern. 

 This is a most interesting species in the various groups of 

 islands." 



The nine Euploeas from Tahiti were the walJceri, H. H. 

 Druce, form of Nipara eleutho, Quoy — a very uniform series, 

 similar to that captured by the President in 1884. Although 

 no Euploeas were to be seen in Earotonga when Mr. Simmonds 

 visited it, a different, more variable, and often much darker 

 form of N. eleutho was taken there by Commander Walker. 

 On the other hand Mr. Simmonds had sent eleven <S and seven 

 ? of Issoria (Atella) egista, Cr., f. howdenia, Butl., from Earo- 

 tonga (May, June, 1920) — a species Commander Walker had 

 seen but failed to catch. The commonest Lycaenid captured 

 by Mr. Simmonds in the Cook Islands was Jamides carissima, 

 Butl. : from Manjaia two Zizera labradus, Godt., were sent, also a 

 Macroglossa, apparently a new form of M. hirundo, Boisd. 



The comparison between the females of H. bolina, L., from 

 Tahiti and Earotonga was extremely interesting. The form 

 of female found in Tahiti and also in other islands,* although 

 on the wing probably indistinguishable from the male, was 

 not quite the same in pattern; for the blue fore-wing patch 

 of the male, made up of three internervular blue spots, was 

 replaced in the female by a white bar composed of four larger 

 spots. Furthermore the two apical white spots in "the fore- 

 wing of both sexes was succeeded in the female, but not in 



* For example. Fanning Island in the Central Pacific (I'roc. Ent. Soc, 

 Lond., 1916, p. xxv). A single individual in Mr. Simmonds' series from 

 Karotonga was of nearly the same mak-like form.
