Family NYMPHALIDAE Swainson. 



Subfamily DANAINAE Bates. 



Genvs HESTIA Hiibner. 



1. Hestia aza (Boisduval), Voyage de V Astrolabe, Lepidoptcra p. 106 (lbi32). 

 The collection contains a very large series of this species, represented bj- 

 both sexes. 



Genus RADENA Moore. 

 2. Radena buruensis sp. nov. 



This species is veiy closely allied to R. luzonica Moore, but may be at once 

 distinguished from it by the prevalently small size of the light spots upon the wings 

 and the consequent enlargement of the black areas in the discal and outer marginal 

 areas of both the primaries and the secondaries. Compared with a series of 

 R. luzonica, this feature is well marked and constant, and permits of an instant 

 discrimination of the two forms. 



The collection contains a series of fifteen examples, which show almost no 

 variation whatever in the markings. 



Genus TIRUMALA Moore. 



3. Tirumala hamata (Macleay), in King's Australia II. p. 4(il (1827) ; Bloore, 

 Proc. Zool. Soc. Land. p. 232 (1883). 



This species is represented by three males. 



Genus NASUMA Moore.

 Proc. Zool. Soc. Lond. p. 233 (1883). 



Mr. Doherty captured two males and two/emales of this species during his stay 

 ou the island.

 Soc. Lond. (1883), and Scndder, Butterjties of New England.) 



The collection contains several specimens of this species in nowise differing 

 from examples captured dnring the past autumn in Pennsylvania. The tendency 

 to melanism shown in the form erippus, which is commonly received from the 

 tropical jwrtions of the American Continent, is not displayed by these specimens. 

 They arc bright in colour, like the form prevalent in the United States, and this is 

 also true of specimens which I have received from other islands of the Eastern 

 Archipelago and from Australia, in which the species has only recently become 

 domiciled. This fact seems to point to the introduction of the species into the
