segments, while in the midst of this suffusion there 

 appeared a pale yellowish- olive semi-lunar patch, situ- 

 ated transversely on the back at the hinder part of the 

 second segment. 



Another variety was coloured with deep rose-pink 

 on the three thoracic and the last three segments, while 

 the middle segments of the body were light green. 



The plain green varieties included individuals of 

 greenish-yellow and others of olive-green. 



Some further enlightenment as regards the food of 

 this species has been given me by Mr. G. F. Mathew, 

 R.N., who kindly informed me that on the 22nd of last 

 June some flowers of Uscallonia were brought to him 

 to look at, when on one of them was detected a larva 

 of Argiolus, about a quarter grown. 



No doubt other food will also be found to have nou- 

 rished this species, and thus a good deal of the old puzzle 

 as to the appearance of the butterfly in localities where 

 no holly grew is done away with. (W. B., 7, 76 ; 

 E.M.M. XIII, 62.) 



It may be interesting to mention that during last 

 month (August, 1876) Mr. Hellins obtained a number 

 of eggs of Argiolus, and sent a portion of them to me, 

 and that all the larvae on hatching were found to be 

 exactly like those of the spring brood, in being fur- 

 nished with hairs and in moving slowly. (W. B., 22, 

 9, 76; E.M.M. XIII 138.)

The observations made by Mr. J. Gredge (' Entomo- 

 logist's Monthly Magazine,' vol. iii, p. 205), that the 

 female of this butterfly deposits her eggs on the heads 

 of Anthyllis vulneraria had for some time been tempting 

 Mr. Buckler and myself to try and rear it from the 

 egg 9 and we have now succeeded in rearing the larvae 

 to their full size.
