appreciably over 2,400 feet, which is the lowest limit of alpine 
insects, and the upper part of this mountain is too bare and 
shelterless for Lepidoptera to exist there. 
The most promising-looking parts for such insects are the 
actual tops of the few mountains which are crowned with rocks, 
like Bingian, Bearnagh, and Commedagh. Round these rocks 
the vegetation is luxuriant, and Salix herbacea grows freely. 
A few species occurring lower down may be mentioned. Saturnia 
pavonia is common, and its larva, together with that of Dicra - 
nura vinula and Pygwra pigra , is common on willow bushes by 
the streams. Hadena contigua occurs, Anarta myrtilh is 
common, also Stilbia anomola , Pachnobia rubricosa and Phyto- 
metva viridaria. The Geometrce include Gnophos obscnvata ) 
Pseudoterpna pruinata , Scodiona belgiana , Larentia ccBsiata , 
Eupithecia nanata , E. minutata and E. sobrinata — this last 
feeding on juniper. A few micros may be mentioned : — Phycis 
fusca occurs in the Happy Valley and also above Donard 
demesne, Mixodia Schulziana is pretty common, and Pamplusia 
mercuriana occurs at the top of Slieve Bingian. 
No doubt further search would result in many additions to 
this rather meagre list, but there is so large an extent of country 
to be covered that for anyone living at a distance it would take 
many years to make anything approaching a complete list of 
the lepidoptera of the Mournes. 
In conclusion, I may say that specimens of nearly all the 
species mentioned are now in the Belfast Museum collection, 
and that it is much to be hoped that some member of the Club 
will take up this branch of field work and add to our knowledge 
of our local Lepidoptera.
