gardens, and are plainly but often very richly coloured. 

 Of these my own collection contains 16 species from 

 Celebes and 15 from Borneo ; but whereas no less than 

 14 are confined to the former island, only two are peculiar 

 to the latter. The Nyruphalidse are a very extensive 

 group, of generally strong- winged and very bright-coloured 

 butterflies, very abundant in the tropics, and represented 

 in our own country by our Fritillaries, our Vanessas, and 

 our Purple-emperor. Some months ago I drew up a list of 

 the Eastern species of this group, including all the new 

 ones discovered by myself, and arrived at the following 

 comparative results : —

Java ... 70 23 33 



Borneo. . . 52 15 29 



Celebes ... 48 35 73 



The Coleoptera are so extensive that few of the groups 

 have yet been carefully worked out. I will therefore refer 

 to one only, which I have myself recently studied — the 

 Cetoniadae or Kose-chafers, — a group of beetles which, 

 owing to their extreme beauty, have been much sought 

 after. From Java 37 species of these insects are known, 

 and from Celebes only 30 ; yet only 13, or 35 per cent., are 

 peculiar to the former island, and 19, or 63 per cent., to the 

 latter. 



The result of these comparisons is, that although Ce- 

 lebes is a single large island with only a few smaller ones
