The HoUy Blue {Lyccena Argiolus) 



While all the otlier Blues delight to sport on low flowery banks 

 in the full blaze of the summer's sun, the Holly Blue prefers to flit 

 among the branches of trees, often many feet from the ground. 

 The larva feeds on the flowers of the holly {Ilex Aquifolium) in 

 the spring, and on those of the ivy {Hedera Helix) late in the 

 summer ; also on the alder buckthorn {BJiamnus Fraiic/ula) ; and it 

 is in localities where these grow that we may find this lovely Blue 

 sporting among the branches, or resting on a leaf with its wings 

 folded together, thus making itself conspicuous among the dark 

 foliage by exposing the pale silvei'y blue of its under surface. 



The upper sides of both the male and female are shown on 

 Plate A^II (figs. 3 and 4 respectively), where the beautiful lilac 

 blue will be seen to have a border of black, wider in the lattei" than 

 in the former.

The Mazarine Blue {Lyccrna Soniargus) 



The male (Plate YII, fig. 5) is deep purple blue, with a narrow 

 dark-biown border, and the female (fig. 6 of the same plate) dark 

 brown. The under side of both sexes is light greyish-brown or 

 drab, with a row of black spots in white rings parallel with the 

 hind margin of each wing, and no reddish or orange spots.
