Transcriber's note: The listed Addenda & Corrigenda have been applied. Deleted sections are marked as ..., all corrections are highlighted like this, and the nature of the correction will appear when the mouse pointer is moved over the marked passage. The colourings of Plate 22 (Terias Elvina) and Plate 51 (Colias Pyrene) are wrong in the copy used—the insects's wings should be pale sulphur and white respectively but are portrayed as dull brown.
