 The only locality where this species occurs in our counties is 

 Maiden Castle Wood near Durham. This station is given in 

 Ornsby's Durham on the authority of Mr. J. Bungay, and Mr, 

 T. Maddison tells me he has found it there recently. The larva 

 feeds on lime, which is by no means common with us.

 these the insect may be bred without any trouble. It is in the 

 Twizell list and in that of Ornsby's Durham as Xanthia fulvago. 

 The former also gives Gilvago, which I assume refers to the 

 variety mentioned below, rather than to the species now known 

 as Gilvago; the latter gives "var. Cerayo," which probably refers 

 to the same form. Mr. Pinlay found the species at Coal Law 

 Wood '' at blossom of Heather, not scarce ;" Mr. Henderson got 

 it at Jesmond; Mr. Ehagg at Haydon Bridge and Thornley; 

 Mr. Hedworth found the larvae '' abundant in catkins on the 

 Derwent;" Dr. Lees and Mr. Gardner met with it in Upper 

 Teesdale ; Mr. Greenwell at Bishop Auckland ; Mr. Sang took
