404 LEPIDOPTERA. 



stripe ; or the whole dorsal area suffused with red-brown ; 

 wing-cases pale green ; antenna-cases either brownish-green 

 or red-brown ; raised dots with their tufts of hairs as in the 

 larva. Upon the food-plant, attached by its anal hooks. 

 (R. South.) 



The moth hides among its food-plant, the marjoram, by 

 day, flying over it at dusk. It is local, confined to chalk 

 downs, hills, and waste places in chalk districts, but in them 

 not everywhere to be found. It occurs, however, pretty 

 generally on ground such as I have mentioned in Kent, 

 Sussex, Surrey, Hants, Dorset, Somerset, and Gloucester- 

 shire. Mr. Atmore has just discovered it in Norfolk; and 

 it is difficult to imagine it absent from some of the inter- 

 mediate counties. Yet, with the exception of a very 

 doubtful record at Sligo, in the West of Ireland, this is the 

 extent of its known range in these Islands. Abroad it is 

 extensively distributed through Central and Southern Europe, 

 Belgium, Livonia, Bithyuia, and the Taurus mountain district 

 in Asiatic Turkey.

 faint golden gloss. Legs pale yellow. Female rather
