date and a warm night, I feel sure they would be plentiful. I 

 imagine our locality has not been worked much at night, as I could 

 not detect the faintest trace of any treacle marks on the trees. 



With us, treacle only produced about a couple of dozen moths — 

 mostly ('irariivu'sia triyravumca, but the night was clear moonlight and 

 so chilly that our hands were almost too cold to box easily. Among 

 the visitors were Cywatophora or, TJn/otira hatis, Xyhipliaaia Jujiatica, 

 Hadena thalasfii)ta, and I'haretra riimicis. The wood is full of ash 

 trees and small aspens, and would, I should imagine, yield plenty of 

 Cranio jJiora lu/iistri and Ci/)iiat(>)i/i(ira or a little later. 



The next morning our doubts about ( '. palaenion were soon set at 

 rest, as we found them almost before we got into the wood. 



They Mere in immense numbers, but had evidently been out some 

 time and wanted a lot of picking over. A few Haviearis hnina were 

 among them and butterflies generally were in great numbers. 

 Brentliis eviilirosyne was getting worn, but we saw no B. selene; 

 Pararge meyera was everywhere and /'. aeytria, although ragged, was 

 very common. 



Gotieptery;!- rhainni, EjtcJtlo'e cardaviinen, Poiyonniiatus icariis, lUiinicia 

 jMaeas, Hesperia malvae, ISHsoniadea tafjes, Aiiyiades sylvaniis, Eiididia 

 mi, K. (jlypldca, Hy/mcrita jacoliaeae and other species made up a great 

 host of day-fliers and numbers of worn I'liisia (jantma and occasional 

 Pyramids caidiii in similar condition are probably heralds of a later 

 abundance of these species. 



I am told that further south these two migrants have Coliaa noceus 

 (ediisa) in their company in which case we may hope for a real 

 " edusa " year again 



More larvae of P. populi and A. ajn-ilina were found on tree 

 trunks, but not many moths were in evidence during the day. A few 

 2'eji/irosia crepiiscularia, Triaena }>si, Lobojiltora liexajiterata, and odd 

 Zonosoma jxaictaria, and Bapta tevierata, were the only species on tree 

 trunks and a newly emerged female I)asychira jnidibiivda was found on 

 the grass. 



At dusk before the T. concolor w'ere taken there were plenty of 

 Geometers on the wing, the best perhaps being Acidalia snbsericeata in 

 some numbers. Others were MelantJiia ocellata, Aspilates striyillaria, 

 Liydia adiistata, Anaitia playiata, Cidaria riissata and among them an 

 occasional Cili.r ylaucata and Cytnotophora or. After T. concolor 

 commenced to fly, how^ever, we gave little attention to anything else 

 and may have missed other things at later dusk. We travelled back 

 on Monday afternoon very well satisfied with the results of our two 

 and a half days collecting.

 Pontia dajdidice, L. — The specimens from many regions I have 

 seen during the last few years confirm the statement I made in the 

 Ent. Pec, of April, 1916, that this species has a very limited 

 variability in Europe. The only geographical variation I have 

 detected consists in the occurrence of form nitida, Vrty., Phopal.
