FAUNA SIMALURENSIS. 193 



NOTE XX. 



FAUNA SIMALURENSIS. 



LEPIDOPTERA RHOPALOCERA, 



FAM. PAPILIONIDAE. 



R. VAN EECKE. 



(With 7 textfigiires and plate 9). 



Amongst a very large number of insects from the island 

 Simalur, west of North Sumatra, received from Mr. Edw. 

 Jacobson and collected by himself, the Papilion idae 

 were represented by eight species, which are common and 

 largely distributed. Two of them were each represented 

 by a specimen, which prooved to be a new variety from 

 that remarkable island. Comparing this material with that 

 of the islands Nias and Sumatra, it seems to me that the 

 fauna of these islands will differ the more and more from 

 that of Sumatra, or that there is a strive after conformity. 



The following is an enumeration of the species received 

 for the collection of the Leyden Museum. 



1. Leptocircus meges Zinck. nov. var. squamosus. 9* 

 W. 4001. 



Hab. Pulu Babi (an islet very near to Simalur). 



It should have been of interest to me to know either we 

 had to do with a new species or with a new variety, but 

 with a single female specimen this question could not be 

 decided, and among the Leptocircinae in the collec- 

 tion of our Museum (not less than 67 specimens), there 

 was no one agreeing with the female from Pulu Babi, 

 though the following localities were represented by one 

 or more specimens: West-Java, Sumatra, Nias, Malacca, 

 Assam, Philippines, Celebes, Biliton and Borneo.
