VIII. Note on Mynes GuerinI, Wallace. 

 By W. H. MiSKiN. 



[Read 17th November, 1S73.] 



In " Notes on Eastern Butterflies," contained in the 

 Transactions of the Entomological Society of London for 

 1869, p. 77, Mr. Wallace, treating on the genus Mynes 

 ( Westwood), describes an insect in his collection (a female), 

 from this colony, and, considering it distinct from M. Geof- 

 froyi (Guerin), makes it a new species under the above 

 name. 



Having been so fortunate as to secure a tolerably perfect 

 series of this very rare insect, I propose to offer a descrip- 

 tion of my specimens, comprising individuals of both sexes, 

 and also a few remarks based upon my observations of 

 these and examination of several specimens in some other 

 collections. 



The result of my investigations is to raise a doubt in 

 my mind as to the correctness of Mr. "Wallace's conclusion, 

 that our species is distinct from M. Geoffroyi. 



It will be observed that very considerable variation 

 exists in the individuals I describe, both in dimensions 

 and markings, and I have noticed the same inconstancy 

 prevailing in other specimens that I have examined beside 

 my own. This is more particularly noticeable in the female, 

 the males as a rule being tolerably consistent in their ap- 

 pearance, except in th-e case of the decided variety I have 

 described, and which, singularly enough, appears to be 

 almost identical with the specimen from Dorey described 

 by Mr. Wallace ; this fact of itself should, I imagine, be 

 alone suflScient to establish the identity of our species with 

 M. Geoffroyi. Other points of difference upon which 

 Mr. Wallace distinguishes his species are not sufficiently 

 important, I respectfully sviggest, to justify the separation 

 of these insects into distinct species, especially taking into 

 consideration the peculiarly variable disposition I have 

 shown to exist in the species.
