LOCALITIES FOR BEGINNERS. 191 
ground under the lower branches ; but great care should be taken 
not to fire the bushes, unless oue is a candidate for one’s name 
appearing in the police column of the newspapers. I have rarely 
heard of large bags of this species being made, but I once got 
about three dozen on one afternoon. While looking for Rutilana 
I have frequently disturbed fine specimens of Cerigo cytherea, 
and these chiefly females. I never remember taking females at 
sugar; they are therefore often wanted by correspondents. One 
of the commonest moths from these junipers at the same time 1s 
Hupithecia sobrinata, which are at Riddlesdown sometimes espe- 
cially fine and well marked. At the farther end of the Downs 
from Croydon are a few stunted yew trees (Taxus baccata) ; these 
are worth overhauling, for from them I have often got moths I 
wanted; I have found Lithosia deplana in them when beating the 
branches. 
Amongst the grass on the open Downs we find most of the 
usual chalk-down plants, as well as wild thyme (Z'hymus 
serpyllum) in abundance, ‘several vetches (Vici), bird’s-foot 
trefoil (Lotus corniculatus), wild mignonette (Reseda lutea), 
hound’s-tongue (Cynoglossum officinale), devil’s-bit and _ field 
scabious (Scabiosa succisa and Knautia arvensis), ke. By looking 
under the shady bushes may be sometimes found orchids of some 
rarity and of exquisite beauty, Orchis purpurea being one of 
these. . 
By sweeping the ground gently on fine afternoons throughout 
the summer, many good and some rare Micro-Lepidoptera may’ 
be taken. One of the species for which Riddlesdown is noted is 
Eviopsela fractifasciana, which occurs in early spring and again 
in August. Of the genus Phycis occurs Adornatella and its near 
ally the beautiful Jlithyia carnella. . Crambus geniculellus and 
C. inquinatellus, the latter frequently, the former commonly. 
Among the Pyralides, which are particularly well represented, 
are Pyrausta purpuralis and P. punicealis, while Herbula cespitalis 
is very abundant; and probably others of greater rarity, if carefully 
worked for. In fact, I should often. remind my readers how 
necessary it is to box everything about which there is the slightest 
doubt, for further examination. How frequently does a rarity get 
overlooked in mistake for something common. As I said in my 
last article, beginners have proverbial luck; but I have no doubt 
this is to be solely attributed to the fact that, wanting almost
