The Lepidoptera come last, and, though few in species, present a 

 fair amount of novelty. On my very first visit to the forest I took 

 three fine specimens of the magnificent Ornithoptera Remus, or a 

 variety of it, for the female does not agree with Boisduval's very 

 imperfect description of it. This made me think it common, but I 

 have since never taken another, except an imperfect female. The 

 common Ornithoptera here is a variety of Amphrisius, with the upper 

 wings entirely black in both sexes. Of Papilios I have three new 

 species, one near P. Sarpedon, but the band narrow, dark green-blue on 

 a velvety black ground, divided into rounded spots on the upper wings 

 and linear ones on the lower. Of this I have a fine series. Another 

 is close to P. Eurypilus, but quite distinct from all I have seen or that 

 are described, by the abdomen above being pure white, which, with 

 the white anal margin of the lower wings, and the white down which 

 extends broadly over them, give the insect a most beautiful appear- 

 ance when on the wing, and enabled me to pronounce it a new spe- 

 cies the first time I saw it hovering over a muddy hole. It flies very 

 strong, is rare and difficult to capture, and I secured very few speci- 

 mens. The third is a rather obscurely marked species, near P. He- 

 lenus. I have only one specimen. Of Papilio Ascalaphus, Bois., I 

 have taken the male and female. P. Polyphontes is common, but I 

 only obtained two or three good specimens. Of Pieris and Euplcea 

 I have several pretty things, and one or two good Nymphalidae ; but 

 the best part of my collection, and what will perhaps please most, are 

 the Lycsenida?, to which I have paid much attention. I have about 

 35 species out of 115 butterflies, and of half of these I have got the 

 two sexes. With health, a better season and a better locality, 1 have 

 no doubt a very fine collection of insects might be made in this part 

 of Celebes, and these I hope to have next dry season, which I have 

 arranged, if all goes well, to spend at Bontyne, situated at the South 

 end of the Peninsula, and close to one of the highest mountains in 

 Celebes. 



I must now tell you where I am off to in the mean time. I am 

 going another thousand miles eastward to the Ami Islands, which are 

 within a hundred miles of the coast of New Guinea, and are the most 

 eastern islands of the Archipelago. Many reasons have induced me 

 to go so far now. I must go somewhere to escape the terrific rainy 

 season here. I have all along looked to visiting Arru, as one of the 

 great objects of my journey to the East ; and almost all the trade with 

 Arru is from Macassar. I have an opportunity of going in a proa, 

 owned and commanded by a Dutchman (Java born), who will take me
