_LOCALITIFS FOR BEGINNERS. 235 
underwings give them the snowy appearance that readily 
separates them from the very abundant Catoptria ulicetana, 
which flies over the same bushes not only then, but during the 
_ whole summer. Chrosis Audoinana is here also in June, and is 
always a prize. . 
Following this valley will bring us to the High Beech Road, 
close to the Robin Hood Inn. Here are four roads meeting. 
We can turn to the right, which takes us towards the Wake 
Arms Inn. On both sides are many sallow bushes, where in olden 
times Mr. Doubleday used to get the purple emperor (Apatura 
Iris) flying-over them, but it is now many years since one was 
seen. About half-way up this road we scramble up the high 
bank to the right, and a short walk brings us to Little and 
Great Monk Woods. In these the whole scene changes, and we 
are amongst the unlopped portion of the Forest. The trees 
stand in striking contrast to their stunted neighbours, and in hot 
weather afford a delicious retreat from the other and less-shaded 
parts of the Forest. LZ. asellus is often common amongst the 
beeches here, while EHphyra trilinearia is in abundance. As I 
have just stated, I think lopping is in the collector’s favour, for, 
excepting these’ two species, little else occurs in sufficient 
quantity to keep us long amongst these tall trees unless it is to 
pick up an odd Stauropus fagi resting on a beech tree trunk, or 
in July Liparis monacha setting in the same manner on the oaks. 
"Returning by the way. we came brings us back to the road, 
which we cross, and work in the opposite direction. ‘Following 
on we come to the King’s Oak, High Beech. If this is in June 
we should especially search the marshy hollow behind the Inn, 
for amongst the scrub beneath the trees was first found Hrastria 
venustula, for long so rare, but which has latterly been more 
frequently taken here and in other parts of the Forest by beating 
the low bushes and by looking for it at dusk when its short flight 
occurs. This hollow is apparently its head-quarters, where the 
larva is said to’feed on cinquefoil (Potentilla tormentilla). 
While refreshing ourselves at the King’s Oak Inn we have, 
on a fine day, one of the finest views in the London district. 
From one side of the house one may see far away over 
Hertfordshire, past the tall chimneys of the celebrated gun- 
factory at Enfield. On the other side the vista closes with the 
Kentish Hills beyond Gravesend, the fine breadth of undulating
