but the latter here were considerably more abundant than 

 near Albari-acin, and probably equalled eight or ten per cent, 

 of the total number examined, and of the remainder a con- 

 siderable number were intermediate between the typical form 

 and var. hispana ; some of these I exhibit ; curiously enough 

 I did not myself, nor did my companions so far as I know, 

 meet with a single example of the violet-blue form here, 

 although Dr. Chapman seems to have found it frequent in 

 this locality. 



'* At Noguera only the violet-blue forms, some of which are 

 exhibited, and a form in which the blue is equally strong, but 

 in which the violet is missing, occurred. I also exhibit this 

 form. These wei-e exceedingly abundant, but unfortunately 

 I could only spend an hour or so amongst them, and as during 

 this time I was iinwell, my observation here could hardly be 

 called exhaustive. 



" From the above observations and on examination of the 

 specimens exhibited, T think it therefore is most probable that 

 the light and dark forms do cross freely when they meet, and 

 that the various forms of intermediate shade are the results. 



" I have abstained from using the name corydonius for any 

 of the Spanish forms taken by myself, because I doubt whether 

 it should be so used. 



" On referring to the examples of this species in the National 

 Collection, I find that the blue Asia Minor forms are well 

 represented ; there are three of these in the series : — 



" 1. A light violet form, much lightei% and with the violet 

 more pronounced than in any of my Spanish examples, and 

 with narrower darkening of the hind margins of the wings. 

 This is labelled corydonius, H.-S. 



" 2. A form with ground colour violet-blue, with very narrow 

 dark margins to the wings. The colour of these specimens is 

 almost identical with the violet-blue examples exhibited, and 

 they agree very well with them in all respects, except that 

 they are somewhat larger, and the darkening of the bind 

 margins is much narrower. They are named caitcasica, Lederer. 



" 3. A form in which the ground colour is deep blue, without 

 any violet, and with the hind margins deeply shaded with 

 black. The colour of these is similar to the deep blue
