Abstract
ACCORDING to a note by Mr. J. J. Walker in the September number of The Entomologists' Monthly Magazine, 1913 is to rank as a “clouded yellow” year, immigrant specimens of these butterflies (Colias edusa) having reached our southern counties in June, and given rise to native broods in August. No British specimen of C. hyale had been recorded this year up to the date of the note.
