228 THE entomologist's record. 



I did no day work in the woods on this visit, as I was scouring the 

 country on a bicycle in search of Acidalia hnmorata, which species I 

 eventually discovered in rather small numbers. I think it quite 

 possible that my locality may be a fresh one and not the recognised 

 one (which I do not know), as I took them whilst trespassing on some 

 private ground of sufficiently alluring aspect to tempt me inside. 

 Arriynnis adippe and belated Brenthis selene occurred on the same spot. 

 A run over the Clifi'e Hill at Lewes was spoiled by the high wind. 

 Rhayades globulariae was either blown away or over, as I could not 

 find it, but a couple of Adscita geryun were taken at rest on birds' -foot 

 trefoil. Agrotis corticea was seen flying naturally in the sun to wild 

 thyme blossom, and a few Merrijieldia tridactyla {tetrad actyla) were 

 kicked up. On a fence under some clematis Exipithecia isogrammata 

 and Pkibalapteryx tersata were at rest, and others were beaten out. I 

 only, however, spent a very little time here. At dusk, in the Hail- 

 sham woods, nothing of great interest occurred. Cymatophora diiploris 

 was common along the hedgerows, and Angerona prunaria in the 

 glades. Timandra amataria was not uncommon, and single Acidalia 

 imitaria, Cidaria picata, and Aplwmia sociella were netted. 



I had little chance, however, of giving attention to dusking, as, 

 after two long days' exploring, I was pressed for time in the evening, 

 and when the treacle was on it was almost time to commence 

 working it. 



For the first time, on this two days' trip, I used Newman's relax- 

 ing-tins. Excellent as these are in many respects, I would offer a 

 word of warning as to insects taken at treacle. Perhaps I left them 

 too long, or packed too tightly, but, when emptied out seven days later, 

 a fair number of Noctuids were soaked through in exuded treacle and 

 hopelessly spoiled. All other captures were in fine order, so in future 

 I shall endeavour to set all my treacle captures and only pack others. 



The Egg-laying of Leptidia sinapis. 



By J. W. TUTT, F.E.S. 

 On the morning of July 30th, 1908, above Staefa, I watched a $ 

 L. sinapis laying her eggs. She Hew very steadily and sloAvly through 

 the low plants on a bankside, examining with her antennae any- 

 thing at all likely for her purpose, but backing steadily when not 

 suitable, and carefully threading her way till the vetchling she was 

 seeking was found. She examined the plant most carefully, and 

 having found it to her liking clung to the stem just below one of the 

 little double leaflets, hanging vertically, and extending her slender 

 abdomen as far as possible from the stem, the wings meanwhile drawn 

 up closely together, then, after a moment, slightly bending her abdo- 

 men to one side she curled it beneath and raised it gradually until it 

 formed a curve, the apex of the abdomen stretching upwards, first 

 level with the legs, then beyond, until it was pressed against the 

 underside of one of the leaflets, which was the point of attack. Having 

 reached it, the front of the abdomen was slowly moved to and fro 

 until the right spot was found, when the pale yellowish egg was 

 deposited and the abdomen lowered, and the $ almost directly 

 commenced her flight. She seemed studiously to neglect all the little 

 plants on which aphides were to be found. One $ examined care-
