VARIATION. 189 



and I have repeatedly come across odd examples whilst they were 

 busily engaged in feasting on the treacle.— Eustace R. Bankes, M.A.,

Lepidoptera at Ci.andon and Folkestone. — Although stormy in 

 the suburbs of London on May 30th, I ran down to Clandon, and 

 was rewarded by a brilliant day (temperature 80^^ in the shade). Lepi- 

 doptera were backward, Kuchlo'i' canlaiiiiut's only just out, Anlais 

 urtirae, Pi/ramt'is atalanta and /'. rrtrr//// were observed ovipositing; 

 Callop/tri/s rubi were getting worn, I'oh/oiiniiatun irants and J', antrarclie 

 only just coming out, although Xi'iiieobiKs lueina was out in good num- 

 bers. Ernaturga atoniaria was swarming on the downs, and some very 

 dark males were taken, in fact, this form seems to predominate at 

 Clandon, whilst at Folkestone the light form occurs most frequently. 

 Bapta taniinata, B. temerata, AstJiena cantUdata, Iliutua crataeijata, and 

 Venilia maculata were all beaten, but in fresh condition. From a 

 garden I obtained two larvae of Plitsia vtoneta on Delphinium : they 

 were hidden in the heart of the buds. From one of five larva' captured 

 on Easter Monday, and which afterwards duly pupated, an imago 

 emerged on June 1st. 



On June 2nd I paid a visit to Folkestone. This was another very 

 hot day (83°F. in the shade). Here, also, everything was backward. 

 PohjommatuH bellan/uN was only just emerging, and of five males taken 

 one showed the greenish -blue tint which characterises some specimens, 

 and I also took one very finely spotted female. Poli/owiitatits icarufi 

 and P. astrarche were just appearing, Ciipido iniiiiina in numbers and 

 in beautiful condition, whilst Calluphrj/^ rnhi was worn. Paiari/c 

 meijaera, too, was observed, whilst one beautiful Colias hi/ale was 

 captured and another missed. Two other collectors whom I met had 

 a specimen each, so that it is possible that the species will be there 

 again in August. Pieris braxdcae, P. rapai', and /'. napi were all 

 abundant. A visit to Lady Wood in the afternoon produced exactly 

 the same species as those I captured at Clandon. — C. P. Pickett, 

 F.E.S. June iSth, 1908.

Aberration of Euchloe cardamines. — I took a beautiful aberra- 

 tion of K. cardamines at Croydon on May 28rd, 1908. It is SSmm. 

 across the forewings (the smallest specimen taken during the day). 

 The discoidal spot is slightly more pi'onounced than usual. The usual 

 reddish-orange patch is replaced by one of lemon tint which extends for 

 a hair's breadth over the spot. The ratio of males to females observed 

 on this day was about 25 to 1, the latter Hying unattended in the hot 

 sun. — Mervyn G. Palmer, 24, Frindsbury Road, Strood, Kent. June

Note on the variation of Papilio machaon in relation to its 

 FOODPLANT. — Somc cxaiiiples of Papilio machaon, turned loose in 

 Surrey, last June, laid ova on Skimuiia ablata, a plant only introduced 

 from China and Japan some thirty years since. Some hundred larva- 

 were brought to me, and they all fed up greedily on the shrub in 

 question, often, indeed, leaving carrot, which I grew at its side, to feed 

 on it. I am trying experiments on a large scale with it this year, as I 

 wish to find out if P. machaon, which I have been told feeds on Shimmia 

 in Japan, though I cannot verify this statement, will vary towards its
