The present paper is a continuation of one on Biak Lepido- 

 ptera by Messrs. Joicey and Noakes which appeared in the 

 Transactions for 1915, Part II, p. 177 et seq. 



The specimens were collected mostly on Biak by Messrs. 

 A., C, and F. Pratt during May and June 1914, and some 

 were obtained on the adjacent island of Soepiori (Mysore) 

 at Korrido. 



The types are in the collection of Joicey except where 

 otherwise stated. 



It may be said here that the expedition made by Messrs. 

 Pratt to the Schouten Islands has added greatly to our 

 knowledge of their Lepidoptera. The present paper 

 brings the number of new forms discovered by these 

 indefatigable collectors up to sixty-one. 



The following notes on the island of Biak and its Lepido- 

 ptera, communicated to us by Mr. Felix Pratt, will be of 

 interest. Very little information on this island is to be 

 found in geographical literature. 



" On Biak, as on most islands out here, the commonest 

 insects are Danaids and Satyrids. To the east, Appias 

 and Catopsilia, particularly the former, were exceedingly 

 common, i. e. for this part of the world. In South America 

 forty to fifty Catopsilia in one sweep of the net is quite 

 possible on a mule road. Such a take out here is an im- 

 possibility; four or five at once would be unusual. To 

 the west, although the country is open and suitable to 

 rapid-flying Pierids. the Appias and Catopsilia were con- 

 spicuous by their absence. In fact, speaking from the 

 standard of mos1 tropical islands, butterflies in general 

 are rather rare on Biak.
