about an hour after, but it did not come anywhere near striking 
distance. I was in hopes of seeing more during my stay, but was 
disappointed. So I turned my observations to E. hyale, a few of which 
I think will be interesting. I found their flight commenced about 
9.30 a.m., and from then till about 1 pan., I never observed them to 
settle ; they flew very swiftly up and down the face of the cliffs, 
making it very difficult to catch them. From 1 pan. till 3.30 pan., 
their flight was less strong and they settled at intervals; it was there¬ 
fore much more easy to secure them. After 3.30 pan. I did not see 
any on the wing, although it was brilliant sunshine. I did not observe 
any to pair, although they would occasionally fight with the common 
“ whites.” One thing in particular I noticed with regard to distribu¬ 
tion ; they seemed to occur more freely in one dip of the cliff's, called 
the “ Horse-shoe ” (a nice sheltered cliff in the shape of a horse-shoe) 
than elsewhere. Whilst the sun was gradually rising to its zenith, 
E. hyale flew on the Avest side of the hollow, at noon they preferred 
the north side, while in the afternoon they shifted to the east side. 
So constant Avas this that in the morning I suav them only on the west 
side and particularly noted that I did not see one on the east, whilst 
at noon none appeared on the south slope, and in the afternoon the 
Avest was entirely deserted ; thus in each case they preferred being 
directly opposite the sun. There Avas another holloAV that led down to 
a field of sainfoin, beyond Avhicli Avas a field of clover, and here I found 
that E. hyale distinctly preferred the sainfoin, but E. croceus (which 
Avas equally common) preferred the cloA^er. 
On the 18th, another visit to Dover, after Polyommatm eorydon, 
&c., produced nine A’ars., including a splendid light golden-broAvn 
female ; at first sight I took it for Coenonympha pamphilus, but think¬ 
ing it a large specimen I netted it; imagine my surprise when it turned 
out a lovely variety of P. eorydon. 
On the 23rd 1 Avent to Raindean Wood in the morning, and Lady 
Wood in the afternoon. I anessa atalanta Avas very common on the 
outskirts, so were its larvae from 1st skin to full-fed, also pupae. In 
fact I saAV a $ lay tAvo eggs on the top of some nettles; so there Avere 
ova, larvae, pupae and imagines of the species at the same time. 
Polyommatas thetis (adonis ) Avere just appearing, only males. 
On the afternoon of the 2oth I stayed in one spot collecting—the 
target dip, a favourite holloAV of P. thetis. Here it is seen in hundreds ; 
any evening, as the sun is going doAvn, you can walk round the ridges 
and pick them off from the long grass with your fingers. As the sun 
vanishes, they gradually craAvl down the grass, and hide aAvay for 
the night. 
Next day Avas dull and cloudy, but still there Avere several insects 
about. P. thetis (adonis ) Avere out in plenty ; females Avere just shoAv- 
ing, some very nicely shot specimens being taken, also one very small 
male no larger than ('upido minima. I captured a very nice underside 
variety of P. alexxs ( ayestis ), the ground colour being pure Avhite and 
the usual black dots replaced by black streaky lines. A search for 
Alanduca atropos Avas reAvarded by tAvo larva) taken. After searching 
half an hour I came across the first one, which 1 almost trod upon, 
feeding Ioav doAvn on the potato flower. 1 had hardly moved Avhen I 
came across the second; I began to think I Avas going to have some 
good sport, but another hour’s search produced nothing. Roth larvae
