146 BRITISH LEPIDOPTERA. 



in the afternoon sunshine in Sutherland, and Lane captured specimens 

 flying in the early morning, May 28th, 1898. Nolcken says that 

 the males swarm in the open woods of the Baltic Provinces, flying 

 in the afternoon sun among the pine trees, also on the Hasik 

 turf-moor. In Tyrone the males fly swiftly over the mountain 

 moorlands (Greer) ; they are taken very freely on the Manx coast 

 near Port Soderick by assembling (H. S. Clarke); in the south 

 they fly almost all the afternoon and early evening in the rides 

 of Chattenden woods and along the edges of the woods that clothe 

 the chalk-hills at Cuxton (Tutt) ; they fly in the sunshine about 

 5 p.m. in early June at Oxted (Sheldon) ; in the afternoon sun 

 on the chalk downs at Box Hill (Bower) ; freely at sunset in 

 North Staffs (Blagg) ; flying at about 8 p.m. on Wicken Fen (Carr) ; 

 flying most plentifully between 5 p.m. and 7 p.m. in the evening 

 at Penrith and Aberdeen ( Varty) ; flying chiefly between 5 p.m. and 

 6.30 p.m., rarely noticed after 7 p.m., in the Middlesboro' district 

 (Lofthouse) ; dash about wildly before dusk on the Cotswolds 

 (Bartlett) ; Lambillion observes that, in Belgium, the males fly 

 during the evening and until about 9 p.m. ; most abundant between 

 7 p.m. and 8 p.m. on Strensall Common (Hewett). The female is rarely 

 seen wild. Tugwell observes that the sexes fly at different times of the 

 day, the male is to be seen flying madly along during the afternoon, 

 whilst the female flies at dusk ; he noticed one of the latter sex in the 

 New Forest in July, 1873, flying over a bog at night, evidently 

 ovipositing. Prideaux first heard and then saw a $ , buzzing over 

 the grass about 8.45 p.m., on June 5th, 1901, but, although followed 

 up, she was soon lost. Clarke says that the female oviposits 

 at dusk, and Holland that he has taken the female at dusk at 

 Sketty Park laying its eggs among the coarse grass ; Bartlett 

 observes that the female hides among the grass, and Walker found 

 but one at Rathmuilan, and that at rest. Bayne has observed 

 females flying at dusk in Epping Forest, whilst Robertson states 

 that at Swansea the females occasionally come to light. Burrows 

 also notes that, on June 2nd, 1886, a female came to light at 

 Brentwood, Dallas-Beeching has captured it similarly at Tunbridge 

 Wells, Carr at Shoreham on June nth, 1899, and Prideaux at 

 Bristol, whilst Benteli captured a single ? at the electric light at 

 Berne in 1893. Fowler says that he has occasionally seen the $ s 

 flying over the heather, straight as an arrow, and, although so 

 large-bodied, they fly so swiftly as usually to avoid capture. East- 

 wood notes that males were assembling to a 9 , sitting on heather 

 and already in copula, in Inverness, on June 10th, 1 891, and that 

 of these he captured nine. Lane found, a female resting on grass 

 about midday, on May 23rd, 1899, at Folkestone, and another sailing 

 over the Beaulieu Lleath, in the New Forest, at 8.30 p.m., on May 

 28th, 1898. Gregson notes a female in cop., before the wings were 

 fully stretched, at 9 p.m., and Pickett observed the males flying swiftly 

 in the afternoon sun at Folkestone, and females sitting on bare ground 

 among long grass and heath, their colour much resembling that of 

 the ground. Dalglish says that in June, 1887, at Glen Mallon, 

 the males were observed freely on the wing, and a few of both 

 sexes were obtained freshly-emerged, whilst suspended from their 

 cocoons, expanding and drying their wings. Barnes notes, in the
