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 rubt.—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 Zephyrus 
quercas, 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. rwbz at Ialta; 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 Ialta and Novorossisk. 
C. dorilis—A very typical male was taken by me at Sarepta on 
May 22nd. 
C. thersamon.—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 Klug’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. thersamon 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 delighted to see this grand 
species once more. Years ago I formed the opinion that it was 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.
