spots or markings. Thymele alveolus. British. 

 Lasiommata .Egeria. British. 



B'. Bkisli, occupying a space near the tip. Antho- 

 caris cardamlnes. British. 



B". Blush, occupying nearly all the area of the 

 wings, and shewn in the intervals between the 

 dark scales. 



Note. — Even where, as in Euplcsa Treitschkei, 

 only a small spot or two of white is shewn on the 

 wings, it is probable that the ground colour of the wing 

 is white, almost wholly obscured by a greater development 

 of the dark scales belonging to the veins. The iride- 

 scent scales, except when forming metallic markings, as 

 on the under side of the Fritillaries, are generally 

 mingled with dark scales (rarely with the pale ground 

 scales), the edges of the areas in which they prevail 

 being shaded off, as in Apatura Iris. British. 



The Common Admiral, Pyramels Atalanta, is an 

 example of the combination of A"' with B". Wherever 

 the black does not extend, is shewn the red blush, which 

 does not, however, reach quite to the tip of the fore-wing; 

 for there, intervals in the black shew the white or pale 

 ground colour in spots. The New Zealand Admiral, 

 Pyrameis gonerilla, on the underside of the fore-wing, 

 indicates plainly that the true character of the red area 

 is that of a red blush on a pale ground. The subject is 

 more fully treated by the Writer in a paper which 

 appeared in the Quarterly Journal of Science, for July, 

 1868.
