 Alis anticis nitidis, saturate ceneis, capite Jiavido-hrunneo. 

 Exp. al. 5 lin. 



Head yellowish-brown ; palpi grey, the middle of the 

 terminal joint darker grey ; antennge fuscous. 



Anterior wings rather glossy, unicolorous dark bronzy- 

 green (almost an invisible green), with just the ghost of a

Mr. Sang met with several specimens of this novelty at 

 the Brushes, near Staleybridge, the first week in June, 

 1870; they were all beaten from oaks ; there was plenty of 

 mountain ash near, but none were beaten from it.
