90 CATALOGUE OF MOTHS. 



of that of Dictaa. It is, however, a much rarer species, and I 

 have found it much more difficult to rear. Hr. Barrett suggests 

 that both species are fond of imbibing drops of water. I never 

 sprinkled their food or I might have been more successful. Mr. 

 Gr. Bolam records it from Alwinton, Kyloe, and Newham Bog. 

 Mr. Finlay found Dictceoides scarce at Old Park, Ketherwitton ; 

 Mr. Maling found a solitary larva on Birch at Sweethope in 

 1869. Mr. Pickard met with it at Wolsingham, Mr. Gardner 

 in Upper Teesdale, and it is given in Ornsby's Durham as occur- 

 ring in Eennie's Lane near that city. About Hartlepool I have 

 found it very sparingly in Castle Eden and Hezleden Denes, and 

 Mr. Gardner has also met with it at Edder Acres.

 This species is well distributed over both counties, but is 

 nowhere common or of very regular occurrence. It is in the 

 Twizell list ; Mr. Finlay found it in most parts of his district 

 but never common ; Mr. Maling found one larva at Jesmond in 

 August, 1869; Mr. Hedworth found eggs on Poplar at Thornley 

 and larva on Sallow at Dunston ; Mr. Brady got two larvae at 

 Ryhope in 1888. Dr. Lees and Mr. Gardner report larvee in 

 various parts of Upper Teesdale ; Mr. Greenwell from Bishop 

 Auckland and Mr. C. Trechmann, Junr., from Castle Eden. It 

 is also given in the Manual as occurring at Darlington. We 

 find it occasionally around Hartlepool, on Poplar more frequently 

 than on Sallow. I have always found it quite on the lower 

 branches, whether in a wood or on a solitary tree, though these 

 may have but few and partly withered leaves.
