180(i.] 3 
cases species have been retained on the strengtli of very old and solitary 
observations ; but the authority on which this has been done will, I 
hope, be held fully to justify the step. That the observations of the 
late Dr. Sail and Mr. Tardy are in many cases unconfirmed, proves, in 
my judgment, not the absence of the insect, but merely the want of 
observers ; and until there are resident entomologists in every part of 
Ireland the indigenous species can never be otherwise than imperfectly 
known. 
Wliere only one or two localities are named, it is not intended 
that the reader should infer that the insect does not occur elsewhere, 
but simply that there was no further information at my disposal. 
The list is still a very meagre one compared Avith that of English 
Lepidoptera ; but when it is considered that an addition of upwards of 
300 species has resulted from the very partial exploration of small dis- 
tricts in Dublin, Galway, and Kerry ; that three-fourths of the counties 
of Ireland, including the whole of the great province of Ulster, and the 
extensive coast line of the island, except a small portion near Dublin, 
are up to the present time terra incognita, I think the idea which has 
been entertained that Ireland was singularly barren and unproductive 
in this order of insects, must be given up ; it has probably arisen from 
the circumstance that the Lepidoptera are not by any means so 
generally distributed as in England ; over a large portion of the island 
grazing farms now extend, wood of any kind is very scarce, and stone 
walls take the place of hedges ; such districts are not likely to possess 
a rich lepidopterous fauna ; but in very restricted localities, and under 
more favourable conditions both species and individuals exist in extra- 
ordinary numbers. As a rule, if you take a species in Ireland you may 
take it in plenty, but you run a great risk of overlooking it entirely by 
missing the precise spot where it alone occurs. The lists of Tortrices 
and TinecB have been drawn up by my friend C. G. Barrett, and though 
undoubtedly still very incomplete, include 150 species not previously 
recorded as indigenous. 
DIUENI. 
Leucophasia sinapis — Abundant near Galway and at Killarney ; but 
has not been noticed in Ulster or Leinster ; only a June brood has 
been observed. 
PiERis CRAT^Gi — Mr. Greene inserts this species in his list on the 
authority of Mr. Hely. I have not met with it, and am unable 
to say where it occurs. 
„ BEASSic^ — Generally distributed. 
„ EAP^ — do. 
„ NAPI — do.
