THE ENTOMOLOGIST. 



Earliest date observed, gen. vern., advena, May 30th, 1912 ; 

 gen. cest., August 14th, 1913 ; and as examples were taken in 

 perfectly fresh condition as late as October 9th, it is probable 

 that a third (or British second) emergence took place. 



24. Gonepteryx rhamni, L. Usually abundant throughout 

 the range, and, of course, one of the earliest butterflies on the 

 wing in springtime. 



Earliest seen. I have not noted it on the Chilterns earlier 

 than April 12th, 1906, as I have not visited the locality in most 

 years at a previous date. Gen. cesL, July 22nd, 1908 ; latest, 

 October 9th, 1913.
