BUTTERFLIES OF BORNEO. 9 1 



the specimen figured by Moore in his Lepidoptera 

 Indica. Plate 204 fig. 1,1a may be considered a typical 

 example of this form. 



3. A form mimicking species of the sub-genus Trepsichrois ; 

 the nyctelius of Doubleday and the cinnamomens of 

 Wood-Major. 



Form No. 2 seems to be intermediate between ua and 

 nyctelius and I am sure that if a large number of these 

 polymorphic females could be collected from a very 

 wide area a graduated series between extreme forms of 

 isa and of nyctelius could be constructed, unfortunately 

 the females of this species are very rare and it will be 

 long before this ideal can be attained ; in the meantime 

 to recognise in the distributional area of the species 

 merely three female forms with distinctive names or 

 numbers appears to be less confusing than to name 

 indiscriminately every topomorph differing from closely 

 related topomorphs in most trifling details. 



Genus Capita. 



106. Cup/m crymanthis, Drury. 



Papilio cn/manthis, Drury, Illust. Exot. Ent. i. pi. 15 fig. 

 3 and 4 (1770). 



Sub-sp. C. crymanthis lotis, Sulz. 



The species has a very extended distribution ranging 

 from India and China to Celebes, Ke and Amboina and 

 to the Philippines. The typical form is restricted to 

 China, Formosa and Hainau. 



107. Cupha arias, Feld. 



JSlessaras arias, Felder, Reio. Nov. Lep. iii. p. 391 (1867). 



In Mantanani Is. off the coast of N. Borneo, in Palawan 

 and the Philippines ; a sub-species occurs in Celebes.
