PYRAUSTA PURPURALIS IN. ApRiIn.—To add to the long list of 
early records for 1921 that have been appearing in the ‘ Entomolo- 
gist,’ it may be of interest to record that I found this species on the 
wing in Gilderdale Forest, Northumberland, on April 27th last—a 
most unusual date. Its usual time of appearance here, when it is 
often abundant, is about the end of June and throughout July.—
