(Johnson), five at flowers of the same plant at Wishanger (Bing- 

 ham -Newland), also at Knutsford (Sidebotham), at Horrabridge 

 (Still), at Swansea (Robertson), at Osmeau Park (Watts), at Dork- 

 ing (Flood), and several at Mount Edgcumbe (Sturt) ; at verbenas 

 in middle of day, continued at flowers for four or five minutes until 

 captured, at Saltburn-on-Sea (F Anson), at sunset at flowers of yellow 

 azalea at Tiverton (Pole), at lilac blossom in the evening at Hasle- 

 mere (Chandler); at verbenas at 8.30 p.m. at Egg Buckland (Briggs), 

 and about 8 p.m. at Kilkea Castle (Douglas) ; at pinks at Wolstanton 

 (Heale), at dusk at scarlet geraniums at Torquay (Grinstead), and at 

 the same flowers at twilight at Newport (Moberly), and at Glanvilles 

 Wootton (Dale) ; at red campion and valerian at Dartmouth (Coles), at 

 Marvel of Peru flowers and white verbenas at Exeter (Hellins), at 

 pinks at Wolstanton (Daltry), at geraniums at Darlington (Backhouse), 

 at the same flowers on damp showery evenings shortly after dusk 

 at Niton (Clarke), at scarlet geraniums just before daybreak (Bloom- 

 field); three at blossoms of lousewort at Bloxworth (Cambridge), at 

 Silene pendula-compacta about 9 p.m. (Hyde), at petunias at Killarney 

 (Birchall), at lilies of the valley at Ennis (Brakey), flowers of white 

 narcissus at Torquay (Stewart), at jessamine at Portsmouth (Larcom), 

 flowers of convolvulus at Reading (Poulton), flying in evening over 

 flowers at Florae (Bellier de la Chavignerie). Other examples have been 

 taken at rest — one on trunk of apple-tree, and another on trunk of pear- 

 tree, at Bournemouth (McRae), resting on bramble at Box Hill (Paskell), 

 one on a truss of straw near Lindfield (Blaber), in a garden at Torquay 

 (Jones), and at Winchester (Nevinson), and at Lyndhurst (Ward-Jack- 

 son), a large 2 on a bank of irises at Preston, Brighton (Morris), on 

 a furze-bush at Lymington (Patterson), on a bank at Langharne 

 (Kaye), a $ on a vine-leaf at Birmingham (Enock), in a greenhouse 

 at Kilkenny (Bristow), in a chalk-pit near Lewes (Blaker), on front 

 of house at Hawick (Guthrie), on a piece of granite at Sandwich 

 (Harbour), on a grass lawn at Lewisham (Stainton). Few examples 

 have been taken at light — Oberthiir states that a specimen was 

 captured at the electric lamp on the Riffel Alp at the end of July, 

 1902; Fletcher notes this species at light, on July 20th, 1898, on 

 board ship at Wei-Hai-Wei ; Frohawk records an example at the 

 light-house lantern of St. Agnes, Scilly, just before sunrise, also 

 one on an electric lamp at Carrow, near Norwich (Laddiman), on a 

 gas-lamp at Dover (Eedle), at light at Limpsfield (Patterson), flew 

 into a room to light at Hunton, near Maidstone (Greville), three 

 round a lamp at Worcester (Edmunds), flew into a room at Coles 

 Cross (Helps), at light at Ventnor (Keet), at Wolverhampton (Morris), 

 at Merthyr Mawr (Hampson), flew into a room at Mullaghmore 

 (Greene). The irregularity in the appearance of this species in Europe 

 is proverbial. Even in Spain it varies much according to the season, 

 being sometimes rare, and at others very abundant, e.g., at Bilbao 

 (Seebold) ; it was unusually plentiful near Berne in 181S (Brown), 

 and swarmed throughout Switzerland in the miserable summer of 

 1883 (Frey), in which year also it was in great numbers from July 7th- 

 August 1 2th at Rohrerberg ; it was abundant, too, in June of that year 

 in Thuringia, and in July of the same year in Baden, whilst it occurred 

 almost continuously the whole of the year 1846 at Freiburg; the 

 spring specimens are always rare in Bucovina, but in certain years,
