272 LEPIDOPTERA. 



A very rare species in this country and oue of which next 

 to nothing is known. A few specimens, wliich seem to be 

 correct, were taken near Bristol thirty years ago, and others, 

 mostly single specimens, are recorded from Wilts, Dorset, 

 Herefordshire (among Genista tincforia and G. anglica), 

 Lancashire, Durham, and Cumberland. I have no other 

 records. Abroad it is found to inhabit Austria-Hungary. 

 Switzerland, Greece, Asia Minor, and Central Asia.
