46 CATALOGUE OF MOTHS. 



say that the imago emerges here in September, and seldom flies 

 much before going into hybernation. It appears again in spring, 

 sometimes as early as April, but more generally about the end 

 of May or June, when the eggs are deposited on the food plant. 

 The larva is full fed in August.

Of this species Wailes wrote, ''probably more generally dif- 

 fused over the two counties than supposed, as the food of the 

 larva, Scahiosa succisa, is plentiful with us. Shull, William 

 Backhouse, Esq.; once at Twizell, P. J. Selby, Esq.; "near 

 Elass, end of June." Ornsby's Durham." 



The efforts of Entomologists, since the publicatiou of Wailes' 

 List in 1858, have not confirmed his view of its general diffu- 

 sion, and only two additional records have come under my notice, 

 "'Near Durham." J. Wood in E. W. I., vol. i., p. 150. (This 

 record, made in 1856, appears to have escaped Mr. Wailes' 

 notice). " Saw two on the wing near Winlaton Mill, May 29, 

 1869." T. H. Hedworth.
