192 THE ENTOMOLOGIST. 
everything, they box all before them. On a fine sunny after- 
noon in July or early August the whole herbage literally swarms 
with Tortrices and Tineina. Sericoris cespitana is common; 
Euchromia purpurana rare at times; while Phoxopteryx comptana 
is, as on all chalk downs, in countless thousands. 
Feeling tired of the Downs the entomologist may. wander 
down to a large chalk quarry at the end farthest from Croydon. 
Here he will find Lycena Corydon commonly, besides other 
species, to repay a visit. ‘There is another old quarry at the end 
of the road from the Downs, where it joins the Caterham Road. 
Here is a more varied growth with plenty of viper’s bugloss 
(chiwm vulgare), with its pretty groups of bright blue flowers ; 
also some fine plants of mullein (Verbascum), I forget of which 
species. On these I once found a batch of shark larve (Cucullia 
verbasci); but while I was making a fine haul of them an irate 
publican, from the public-house opposite, ignominiously turned 
me out. ‘hat is the only time I have been interfered with on or 
near Riddlesdown, where I have no doubt on nearly every occasion 
the collector may work away in peace. Iam not aware whether 
there is any right to wander or no over these Downs, but I have 
never been otherwise questioned. 
_ There are some good-looking meadows at the bottom of the 
valley. Never having worked them I cannot say much about 
them, but I have heard that sometimes Acontia luctuosa is to 
be taken—by the collector who can run—flying over the clover 
fields. All the valley seems good up towards Caterham. ‘There 
are other Downs in the neighbourhood, on one of which, Purley 
Down, the junipers are larger and older, some ten or more feet 
high, but I have always done better on Riddlesdown with much 
the same fauna. Purley Down is to be reached by turning to the 
left from the Riddlesdown lane soon after leaving the Brighton 
Road. Passing also under a railway arch through the old 
Purley oaks, straight on until an unfinished and ‘abandoned 
railway cutting is reached, when Purley Down will be seen on the 
right. I understand this’ is more strictly preserved, and the 
collector may be asked to leave sometimes. 
I have never sugared on Riddlesdown, or in its neighbour- 
hood, but it would be well worth trying. <A train leaves Kenley 
just after 10 o’clock p.m., but trains from West Croydon to 
London may be got up to midnight, or nearly so.
