CATALOGUE OF MOTHS. 149 



A very common species everywhere. Oculea is one of the 

 most variable of the ^N'octuse, but all the forms occur everywhere 

 and shade into each other by imperceptible gradations. A marked 

 change has taken place, however, since 1855, when I commenced 

 to collect. Yery light variations were then common, and the 

 darkest was far from the most abundant. Now, the lighter forms 

 are never seen at Hartlepool, and the darker ones are much the 

 more numerous. The same remark applies to Miana strigilis.

 A strictly southern species, of which one record exists for each 

 county. It is in the Twizell list, but there being no trace of 

 the specimen in the collection, I always assumed it had been 

 wrongly named, but in 1875 Mr. Gardner took a specimen at 

 sugar at Hartlepool, which makes Mr. Selby's record more pro- 

 bable, Mr. Barrett says the species is mainly confined to marshy 

 places and the banks of rivers. The larva feeds on Phalaris 

 arundinacea, the variegated form of which is commonly grown 

 in gardens as ''Kibbon Grass." It is possible that a larva or 

 pupa might be transferred with a clump of the grass from a 

 southern garden. It must be added, however, that 1875, the 

 year of Mr. Gardner's capture, was an unprecedented year for 

 sugar. Species came in large numbers that season, that we 

 never took previously except singly, and others occurred that we 

 never saw before or since.
