grass being used. Upon old bushes of sallow, crab, black- 

 thorn, and buckthorn, usually upon the branches which are 

 much over-grown with small lichens, the case closely re- 

 sembling a small bit of old dead twig. 



July or August to May. 



Pupa undescribed, in the larva-case. 



First recorded in this country by Mr. Mitford, who gave 

 unusual attention to the present group. He found cases in 

 the Bishop's Wood at Hampstead, just outside London, and 

 reared both sexes. It has also been obtained from Box Hill, 

 Surrey ; the New Forest, Hants ; and Epping Forest, Essex. 

 There is little doubt that it would be found in many of our 

 southern woods, in damp spots where the bushes are rough 

 with lichens, if carefully looked for. At present it is in very 

 few collections, and little is known of its habits. 



It appears to inhabit France, Germany, and Western 

 Russia.
