Lastly I should add that my friend, in maldng the collection and 

 in offering them to me for examination, had no idea that they were to 

 be utilised for these notes. 



The collection comprises 274 examples, representing 68 different 

 species, no less than 108 specimens being divided among 5 species of 

 Banainse. The number of different species of butterflies at present 

 known from Borneo is approximately 791. The following table shows 

 the number of species Icnown of each family together with the number 

 of species and individuals obtained in this collection.

The first point to notice is the relatively large number of 

 Nymphalidx obtained— no less than one- sixth of the total number 

 known from Borneo — while over 71 per cent, of the specimens in the 

 collection belong to this family. 



If, furthermore, we analyse the Nymphalidfe so as to show the 

 relative numbers of each group or sub-family, we obtain some 

 significant figures.

The very large proportion of Danainas (Danaini and Ewplceini) 

 provides excellent evidence in support of the Miillerian theory of 

 mimicry, which postulates associations or combinations of distasteful
