TRIFID^. 301 



October, hybernates in the earth full grown. (Condensed 

 from Buckler.) I have no reason to believe that it feeds 

 again after hybernation in this country. Abroad it is said to 

 feed in the spring on low plants. 



Pupa short and stout, light brown, with very conspicuous 

 spiracles. In a small chamber in the earth among the roots 

 of plants. 



The moth does not seem to be readily attracted by flowers, 

 but comes to sugar in its very restricted haunts ; its habit 

 appears, however, to be to sit on grasses at night, where it may 

 be found by searching with a lantern ; when flying it will come 

 to light. It hides by day at the roots of the short grass of 

 the downs, but the female has occasionally been taken 

 tumbling or running over the grass, in hot sunshine, in the 

 afternoon. Apparently almost entirely restricted, in this 

 country, to chalk hills and downs, or limestone mountains. 

 In Kent at Dover, New Romsey, Folkestone, Sevenoaks and 

 elsewhere ; in Sussex on the downs near Lewes, Brighton, 

 Worthing, and probably on all the chalk hills; in Dorset, 

 near Studland, Isle of Purbeck, but rare ; more frequently 

 at the Isle of Portland ; rare in Devon, recorded only from 

 Plymouth and Torquay ; also at Durdham Downs near 

 Bristol ; on the Cotswolds, Gloucestershire ; at Newbury, 

 and once at Reading, Berkshire ; at Whitchurch and 

 Chinnor, Oxfordshire ; on the Gog Magog Hills near 

 Cambridge ; and at Brandon, Suffolk. Also in the west near 

 Leominster, Herefordshire ; and at Llangollen in North 

 Wales. This appears to be the extent of its range in these 

 Islands ; abroad it is widely distributed over Central, Western, 

 and great part of Northern Europe ; Northern Italy, 

 Turkey, the Ural Mountain district, and Armenia,
