36 BRITISH BUTTERFLIES AND MOTHS 



It lias lately been observed that several of the females 

 of the genus Orgyia, which occur in the south of Europe, 

 approximate in their habits to these females of Psyche, 

 having short and useless legs, and not emerging from 

 their cocoons. (See ' Journal of the Linnean Society of 

 London,' Zoology, vol. vi., p. 156-164, ' On the Abnor- 

 mal Habits of some Females of the genus Orgyia.') 



In the great tribe of Noctuina, or Night -flying Moths, 

 we meet with several individual species which fly freely 

 in the daytime, such as Leucania conigera, which may 

 be seen buzzing at flowers in the daytime; Charseas 

 graminis, flying over heaths at all hours of the day ; 

 Miana furuncula, which flies in numbers in the after- 

 noon ; Celaena flaworthii, which flies both in the after- 

 noon and evening; Agrotis porphyrea, A. Incernea, Tri- 

 phsena lanthina and T. interject a. All the species of 

 Heliothis fly by day and also at dusk, whereas the species 

 of Anarta are true sunshine-lovers, and the little Helio- 

 des arluti is never seen on the wing except in full day- 

 light. All the pretty little NoctuaB which constitute the 

 section Minores are day-fliers, and Plusin gamma and 

 P. interrogationis are freely on the wing both day and 

 night. The species of Toxocampa are also true day- 

 flies, and the showy Catocala nupta flies freely in the 

 daytime, but is also on the wing after dark ; Euclidia 

 Mi flies in meadows in the daytime, E. glypliica in 

 open places in woods, and Phytomctra &nea may be 

 noticed disporting itself on heaths. 



The remainder of the large group of Noctuina are at 

 rest in the daytime, and must be sought for on palings 

 or trunks of trees. The species of Bryophila may be 

 found on walls; Polio, chi on the stone walls of our 

 midland and northern counties ; and the curious Dasy-
