L. Ruhi passes the winter on a full fed larva, emerging in 

 early spring to bask in the morning sun, but never eating any- 

 thing. The larva cannot be forced, as I have shewn elsewhere 

 (E. M. M., vol. xxxiii., p. 199), but is very easily reared if 

 found after hybernation. I have this year (1897) bred several 

 forms in which the central band varies in shape and width till 

 in some specimens there is but a double ochreous line crossing 

 the wing. I never met with these varieties before except in one 

 single specimen. These were from larvse taken on the sand 

 banks between Hezleden Dene and Black Halls.

 This interesting insect is common throughout our district, ex- 

 cept on the wetter moorlands ; perhaps most abundant on the 

 coast, but generally plentiful in the larval state on the coarse 

 grass of hedge sides, where it sits conspicuously stretched out on 

 a dry stem. It is a species that varies little in markings but 

 considerably in depth of colour. From larvae found here Mr. 

 Gardner and I have sometimes reared females almost as dark as 

 the males, but we have never seen the very pale forms that 

 have been met with in the fens. 



I do not quote localities, as it is in all the lists and occurs 

 even at such places as Holy Island and St. Mary's Island.
