broadly banded with miuute pitting ; cremaster rounded and 

 wrinkled, with two side and four terminal spikes. 



In a slight cocoon of open silken threads, among the food 

 plant. (Described from specimens furnished by Mr. H. J. 

 Turner.) 



The moth is said to inhabit dry grassy and heathy spots, 

 and also meadows. In this country, so far as I know, it has 

 only been found on some heathery hills in the chalk districts. 

 It sits by day among the heritage, and is easily disturbed, 

 flitting about in a lively manner. The first specimens 

 observed in this country were taken among heather, near 

 Lewes, Sussex, in June 1887, by Mr. C. H. Morris, and were 

 recorded by Mr. J. H. A. Jenner. Many more specimens 

 have been taken in the same locality in subsequent years. 

 One pi-evious capture has since been recorded — a specimen 

 taken — possibly in the same district — many years ago by the 

 late Mr. Desvignes, and since placed in the collection of the 

 late Mr. S. Stevens. It had been supposed to be merely a 

 variety of Strenia dutlirata. The moth is, however, very 

 much more like Fidonia ntomarii(, except for its simple 

 antenna?, and it is just possible that it may, in other localities, 

 have been mistaken for that species. So far as our present 

 knowledge goes, however, it is confined in these islands to 

 the one very restricted locality, in the county of Sussex, 

 already mentioned. Abroad it is widely distributed in the 

 central and temperate northern regions of Europe, and is 

 found in Central and Northern Italy, Bulgaria, Southern 

 and Eastern Russia, Bithynia, and North-East Siberia.
