iYlacroglossa stellatarum, etc., In Co. Down. 



I took over half a dozen examples, and saw many others, of the 

 Humming-bird Moth hovering over the flowers of fuchsia, chiefly in 

 Donard demesne, Newcastle, during the first two weeks in September. 

 It seems to be common in Ireland this year from all accounts, but its 

 occurrence so far north may be worth recording. 



Pyrameis atalanta was exceedingly abundant also in the same place, and 



I might have taken scores of them had I been so disposed.

Notes on Lepldoptera. 



I have seen three " Clouded Yellows" (Colias edusa) in North Tipperary 



this season, one early in August and two on the 29th September. I am 



not aware that it has yet been recorded from this locality. The 



Humming-bird Hawk-moth (Macroglossa stellatarnni) was rather abundant 



in the gardens around Nenagh this summer. I have counted seven in 



one small corner together. I have also seen two specimens of the Irish 



Burnet {Zygoma nubigena) near Lough Derg. In 1894 I also met with it 



in the same place, but not in the intervening years. On the 16th 



August, when landing at Urra, on the shore of Lough Derg, I found 



myself actually surrounded by butterflies. A plant with a large flat 



pink-headed flower 1 grew along the shore for a hundred yards or so, 



enclosed in a wooded bay, and in and about this plant I counted over 



two dozen of Pyrameis atalanta, several Vanessa io, Argynnis paphia. two 



other Fritillaries I did not recognize, Clirysop/iamies pklceas, Pararge egeria, 



P. megcera, and a few Whites. On the same day I caught a Clouded 



Yellow near by. Such a number and variety in one small spot was 



extraordinary.

A friend journeying from Belfast to Ballyshannon brought me from 

 Co. Sligo what he was pleased to call " Fossil Ivy " — a piece of Carboni- 

 ferous limestone very much weathered, the coral standing out just like 

 the stems of Ivy. 



The stone measured 5 inches by i\ inches, was very rough and full of 

 crevasses. When handling it I was attracted by a small beetle hiding in 

 one of the holes. Making a careful search with a field microscope I 

 discovered five beetles, all of one species {Longitarsus melanocephalus) and 

 fifty-four live Helix rupestris. Only four or five of these were full grown. 



The stone is used as the common fencing stone of the district.
