Ixxii 



Specimens of Troides joiceyi J. and N., were shown to 

 illustrate the transition from the typical form with black 

 lateral abdominal sclerites, and the form without any such 

 black scaling. These forms were taken at the same place. 

 The Morphofaenaris connects schonbergi from Stephansort 

 with kenricki from the Arfak. 



The Morphopsis inhabits the dark forest at 5000 ft., and 

 flies at dusk. Descriptions of these new forms will be published 

 in due course.

OF Hypolimnas bolina, L. — Prof. Poulton exhibited speci-

 from Mr. H. W. Simmonds of the Department of Agriculture, 

 Suva, Fiji :—

" As to the Tahitian luitterflies, H. holina is most abundant,, 

 but apparently all males. There seem to be hundreds of 

 males to one female. I say ' seem to be ' because the two 

 (now four) females I have taken are almost like the S, and, 

 as all are worn, I may pass them by. 



" Everything here is, so far as I have seen, Polynesian- 

 New Guinea in its origin, except probably some of the Hymen- 

 optera which seem more numerous in individuals and species 

 than in Fiji. Possibly some of the beetles also may be New 

 World, but I have only seen five species, and two of these 

 are akin to ^ew Zealand forms. There is no native bush 

 left in valley or hill, up to 2000 ft. or more, in this district, 

 and hardly any tracks. I hope to reach the forest before I 

 leave, but as yet have only seen about four indigenous trees. 

 The country is all Lantana. The trees are : Metrosideros (or 

 very close to it), a New Zealand type ; Hibiscus, identical with 

 a Fijian species; two Timber trees, very close to Fijian 

 species."

" I have just got back to Suva and hope to send you a few 

 specimens by this mail from Rarotonga, Manjaia and Aitu- 

 taki in the Cook Is., and Tahiti in the Society group. I did
