272 THE ENTOMOLOGIST. 



see in the Russian specimens from those I have from Hungary is, 

 that on the under sides of the former the ground colour is grey, and 

 of the latter grey-brown. 



Callophrys rubi. — The most remarkable race of this species that 

 I have seen was common at Novorossisk. It is a small form with 

 an average wing expanse of 30 mm. ; the under side is typical, but 

 the upper sides of the wings in both sexes are black, without the 

 slightest tinge of brown, and the whole surface has a grey-blue 

 sheen, similar to that which is found in male examples of Zephynis 

 querclis, but of course the sheen is not the same colour as in that 

 species. I propose for this remarkable race, which so far as I am 

 aware is confined to the Caucasus, the name of var. schamyl n. var. 

 I saw, but did not capture, a few examples of C. rubi at lalta; these, 

 as far as I could see, were very typical. A few examples were seen 

 at Sarepta on the outskirts of the " Tschapurnik Wald"; they are 

 rather darker brown in colour than the type, and have an expanse 

 of about 34 mm. 



Chrysophanus phlaeas. — A few very typical cold-form examples 

 were seen at lalta and Novorossisk. 



C. clorilis. — A very typical male was taken by me at Sarepta on 

 May 22nd. 



G. tliersamon. — Abundant at Sarepta, but somewhat local, chiefly 

 frequenting the railway banks and the adjacent slopes ; a bright 

 form, especially on the under side, on which the grey ground colour 

 of the hind wings is much lighter, and the copper ground of the fore 

 wings much brighter than in Hungarian examples. I suppose they 

 would all come under King's var. omphale, but it is difficult to know 

 where the type ends and this variety commences. The chief distinction 

 that Klug makes is that his var. omphale has tails on the inferiors ; 

 and he figures the males and females with tails approximately 2 mm. 

 and 4 mm. long, respectively ; but all C. tliersamon that I have seen 

 have tails in both sexes, if only rudimentary ones. My Sarepta 

 specimens have tails, in the males about three quarters of a 

 millimetre in length, and in the females 2 mm. in length, whereas 

 Hungarian first brood examples, which I understand to be the type, 

 have only very rudimentary tails, of not more than a quarter of a 

 millimetre in length. Individuals were continually emerging at Sarepta 

 during the whole period of our stay. 



C. dispar var. rutilus. — I was much dehghted to see this grand 

 species once more. Years ago I formed the opinion that it w'as the 

 most beautiful European butterfly when seen on the wing ; and now 

 that I have observed all the European species, with the exception of 

 about sixty, I can fully confirm this opinion. One can imagine what 

 our British type, the finest form of all, must have looked like. I first 

 saw var. rutilus at Sarepta in a small swamp in the railway cutting, 

 a mile or so to the south-east of the town, on May 26th. Afterwards 

 we found that it was generally distributed in the small swamps that 

 are to be found in certain valleys which lie towards Tsaritsyn ; it 

 was not very common there, but I expect it was abundant in the 

 large marshes between the arms of the Volga, had one cared to work 

 them, which I did not. The form is a very similar one to that 

 found near Budapest, and quite as large.
