O " [June, 
The only species with which 8c. lasistrigalis can possibly be con- 
founded is 8c. ambigiialis ; but the greater width of the fore-wing, giving 
the appearance of its being actually shorter, the rounded apex, and 
especially the vertical apical margin, together with the distinct basal 
streaks, the oblique commencement of the first line, &c., are amply 
sufficient to separate it from that insect. 
I believe that 8g. lasistrigalis WiWhe found pretty generally mixed 
up with 8c. amhigualis in collections. I detected several examples, 
both ^ and $ , among a number of Scoparice forwarded to me for 
investigation from Haslemere, by Mr. Barrett. Mr. Bond, a few years 
since, noticed the insect in some numbers at Tilgate Forest ; but, con- 
sidering it at the time a variety of amhigualis, contented himself with 
the capture of only two or three specimens. Mr. Horton has also sent 
me this species for identification from "Worcester ; and I have noticed 
it mixed up with 8c. amhigualis in some of the collections to which I 
have had access. 
I may add that in a future number of the Magazine it is my 
intention to make an attempt to smooth the difi&culties which beset the 
study of this interesting but much neglected little group ; and that 
Mr. Rye will draw on wood most of our indigenous species, for the 
purpose of illustrating my proposed paper on the subject.

THE LEPIDOPTEBA OF IRELAND. 
BY EDWIN BIBCHALL. 
Ten years having elapsed since the publication by the Dublin 
University Zoological and Botanical Association, of lists of Irish 
Lepidoptera, drawn up by the E,ev. Joseph Greene and the Rev. A. E. 
Hogan, together comprising 636 species, I venture to offer the following 
revised and extended list, in wliich 961 species are recorded as indige- 
nous, amongst them seven species not known to occur in Great Britain. 
Much has yet to be done before a catalogue, even approximately 
complete, can be prepared ; still I hope that a record of the present 
state of our knowledge of the distribution of Lepidoptera in Ireland 
will not be without value as a basis for future observations, and the 
sooner it becomes obsolete the better will its purpose be answered. 
" Enougli if something from our hands have power, 
To live, and act, and serve the future hour." 
I have been unwilling to reject any reputed indigenous species 
which could be retained with the least show of reason ; and in some
