New and little-known Butterflies from the Island 

 OF BuRU. — Mr. G. Talbot, on behalf of Mr. J. J. Joicey, said 

 that the brothers Pratt had collected on Buru for Mr. Joicey 

 from January to May 1922, and had succeeded in making a very 

 fine collection of Lepidoptera. Collections were made on the 

 south coast at Lek Soela and in the mountains in the south- 

 west district at elevations of from 2700-6000 ft. 



The principal discovery was a new Troides, which has been 

 described in the " Bulletin of The Hill Museum," vol. 1, pt. 2, 

 under the name of T. praftorum, J. & T. Its habitat was found 

 to be very limited in extent, and perhaps for this reason the 

 species remained undiscovered by Dutch collectors who have 

 been all over the Island. 



A remarkable aberration of the S' of prattorum was obtained 

 at the coast between February and March, but there is some 

 doubt as to this locality. This specimen presents some of the 

 characters of T. helena boiiruensis Wall., with a preponderance 

 of the characters of T. prattorum. The fore-wing is shaped like 

 praUormn, but with faint vein stripes. The hind- wing is more 

 like bouruensis, especially in the form of the cell and in general 

 markings ; there is, however, a distinct but slight opalescence 

 on both sides. Whether we have to do with an aberration 

 showing reversion to a primitive type or with a hybrid, is a 

 question we cannot answer. Aberrations are more numerous 

 than hybrids, and it may be more reasonable to suppose that 

 this specimen represents some ancestral type. 



Troides helena bouruensis Wall. — Three pairs are exhibited to 

 show the variation in both sexes. 



Papilio ulysses ampelius Eoths.— The most westerly race 

 of this species, hitherto only known by one (J. The (^ and $ 

 are shown. Found at the coast and in Central Buru. 



Dichorrhagia ninus, subsp. nov. — This form is shown in 

 comparison with typical 7iinus Feld., from Ceram. Obtained 

 up to 2700 ft.
