CnoKTOBius Davus — Common in Galway, Mayo, and Kerry. All the 
Irish and Scotch examples of this insect which I have seen 
are the typical form of Davus of Fab. ; they may be dis- 
tinguished from the variety which occurs on the bogs of 
the north of England by their larger size, and by the more 
or less complete absence of the ocelli on the undcr-surface 
of the hind-wings : the English variety is the Eothliebii of 
German authors. 
„ PAMPHiLUS — Common everywhere. 
Thecla eubi — Common Dublin, "Wick low, and Kerry. 
„ QUERCus — Do. do. 
„ BETULiE — A^ery common in the lanes and roadside hedges ot 
the south and west of Ireland in August, frequenting the flowers 
of the bramble, and settling the moment the sun is obscured, 
when it may readily be taken with the fingers ; has not been 
noticed in Ulster or Leinster. 
POLYOMMATUS PHL^AS CommOU. 
Ltc^na MOtOs — The Murrough of "Wicklow, and near Koss Trevor. 
„ AGESTis — Dundrum, near Dublin. 
„ ALEXIS — Common everywhere. 
„ COETDON — Mr. Greene inserts this species on Mr. Hely's 
authority. I have not met with it. 
„ ALSirs — Very common in Galway ; also occurs near Belfast, 
and on the Portmarnock sand-hills. 
„ AEGiOLUS — Generally abundant throughout Ireland where 
the holly, on which the larva feeds, is a very common tree. 
Nemeobius lfcina — In Mr. Tardy's collection, now incorporated with 
that of Trinity College, Dublin, there are specimens of this insect, 
but I am unable to say where captured — most probably in the 
county Wicklow, a district he searched assiduously for many 
years. I have not met with the insect. 
Thanaos tages — Hitherto only noticed near Galway. 
Hespeeius sxltanus — The Murrough of Wicklow. 
„ LiNEA — Powerscourt and near Cork. 
It thus appears that only 43 of the 64 British Butterflies have 
been observed in Ireland. The 21 absentees may be thus classified, 
following the divisions of Mr. H. C. Watson's " Cybele Britannica": — 
Argynnis Etiphrosyne — *\ 3 species of the " British Type," so called 
„ Selene — v from the universal difi"usion of the species 
Syrichthus alveolus — j throughout Great Britain. I have little 
doubt all three will eventually be found in Ireland, especially as 
they occur in Scotland, from whence Ireland seems, to a large 
extent, to have derived its insect population.
