method of spreading what is called “sugar” on the trees to 
attract Noctuce, but it has never proved a success. Indeed, the 
same may be said of every place that I have tried, except the 
Donard demesne at Newcastle. The cause is probably the 
dampness of the majority of the otherwise suitable localities, 
including most of the wooded glens in the district. Two of the 
less universal butterflies occur here, namely, Par urge egena 
(Wood Argus) and Epinephele hyberanthus (Ringlet), the 
former being very common. Euchloe cardamines (Orange-tip) 
is also common in the glen, and still more so on the mountain 
just above, where I have taken specimens of a dwarf race. 
Macro gloss a bombylijormis is common at the top of the glen ; 
the larva feeds on Scabiosa succisa , and the moth is fond of the 
flowers of Pedicular is. Of the Bombyces , Spilosoma fuliginosa 
is common, also Lophopteryx camelina and Thyatira derasa and 
batis. The Noctuce include Miana arcuosa , Grammesia tn- 
grammica , Dianthoecia nana , and Plusia bulchrina. and of the 
Geometrae , which are more abundant, the commonest are 
Metrocampa margaritaria (Light Emerald), Selenia bi lunar la, 
Odontopera bidentata , Cabera pusaria and exanthemana, 
which fly in swarms about dusk, Strenia clathrata, Eupithecia 
lariciata among the larches in the higher parts, Hypsipetes 
impluviata among alder, Melanthia bicolor ata and ocellata , 
Anticlea badiata and nigrofasciaria and. Cidana silaceata, o 
which the larva feeds on the enchanter’s nightshade. 
We are on very different ground when we come to explore 
the hills, and we meet with an entirely different insect fauna. 
Species which are universal on the lower ground are entirely 
absent on the heather, and naturally the heath-feeding species 
do not occur away from the food-plant. Besides the heat 
species there are several which feed on Vaccinium, on various 
low plants, on ferns and grasses, and on Salix repens. The last 
is comparatively scarce on most parts ol the Belfast hills, so 
that the fauna is poorer than it would be if this favourite food- 
plant were more abundant. On the steep eastern face of the 
hills many plants grow which are not to be found off the Chalk,
