40 DIURNAL LEPIDOPTERA. 



[I have thought it best to add here two corrections to the former part of this work. For 

 Myrina Thymbrteus, page 28, Horsfield's name of Jalindra, having the priority, must be 

 adopted ; and Myrina Syrinx of Felder (p. 34) must give place to M. Onyx of Doubleday, 

 this species having been previously described by Horsfield and Moore. The two species must 

 therefore stand thus : — 



Myrina Jalindra. 



Amblypodia Jalindra, Horsfield (1829). 



Sithon Thymbrasus, Hubner, Zutr. f. 671, 672 (1832). 



Myrina Onyx. 



Myrina Onyx, Horsfield Sf Moore (1857). 

 Myrina Syrinx, Felder (I860).] 



Genus IOLAUS. 



Iolaus, Hubner. 



I hope and trust that Iolaus, as I have grouped it here, comprehending as it does 

 part of Amblypodia and part of Iolaus of Doubleday and Westwood, will be considered 

 a good genus. I have taken P. Eurisus of Cramer as the type. The palpi have the 

 second joint very long, the third joint (long in the females) projecting outwards, as shown 

 in Plate XX. The subcostal nervure has a third branch. The males of most of 

 the species are remarkable for a tuft of long hair, varying in colour, which projects 

 inwards from, and at a right angle with, the inner margin on the underside of the 

 anterior wing. Some have the margin projecting outwards as in Euplcea, all met by a 

 polished surface on the posterior wing. I have never seen I. Ismenias of Klug and 

 Ehrenberg, but have little doubt that it has its true position here. I do not know 

 /. Cippus of Godart.
