5 species of the English type ; none of them 
occur in Scotland except A. Adippe. The 
others are most abundant in the south 
of England, and all decrease in frequency 
northwards. 
11 species of the " German Type," also 
all absent from Scotland, and mostly 
attached to the south-eastern portion 
of England.

Hesperia ActcGon — One species of the " Atlantic Type." It is not 
improbable that this insect will be found on the south coast. 
There is no part of the British Islands in which an Atlantic type 
of fauna and flora is so strikingly developed as in the south-western 
portion of Ireland. 
Erehia blandina— One species of the "Scottish or Northern Type." 
As this insect is widely spread over the jS orthern part of Great 
Britain, and abounds in Argyleshire almost within sight of the 
Irish shores, I confidently anticipate its discovery in Ireland. I 
have never collected in Ulster, where it is most likely to be found. 
Enjoying, as Ireland does, a milder climate than any other portion 
of the British Islands, the absence (if it should prove such) of the 
foregoing 21 Butterflies, of which 16 are also absent from Scotland, is 
a remarkable circumstance ; and I know of nothing in the physical 
condition, or in the flora, of the island, to account for it. 
In the present imperfect state of our knowledge of Irish Lepidop- 
tera, perhaps it is premature even to hazard a conjecture as to the 
cause ; if, however, we suppose the separation of Ireland from England 
by the formation of St. George's Channel to have taken place previously 
to the introduction of the bulk of the present fauna, and a connection 
to have existed with Scotland to a later date, it will offer an explana- 
tion of the northern character of the Irish fauna which is very strongly 
marked even in the extreme south of the island at Killarney, amidst 
conditions of climate and vegetation offering the most complete contrast 
with Scotland within the limits of the British islands.
