HEATH.FREQUENTERS 157 



butterflies the Large Heath (Cwnonympha 

 typhon), Plate XVI., Fig. 6, and the Small 

 Heath (Ccenonympha pamphilus), Plate XVI., 

 Fig. 7. Both are tawny, but the former is 

 larger, and bears one or two indistinct eye- 

 spots on each wing, while the latter has only 

 one near the tip of each forewing. Specimens 

 of the Large Heath vary greatly in the 

 number and distinctness of the spots. Both 

 are sluggish fliers and easily taken. In 

 company with the Small Heath is usually 

 to be seen the Common Blue (Lycsena icarus), 

 which I have not figured, as it is so well 

 known. Every one must have observed 

 this little lilac-blue butterfly flying across 

 downs, or banks by the roadside, over the 

 harebells, and looking as if some of the 

 blossoms had become instinct with life. The 

 strong tinge of lilac in its colour serves to 

 distinguish the male, at any rate, from other 

 blues. The female is brown rather than blue, 

 with a row of small red spots at the edge 

 of the wings. About the same size as this 

 Blue is the Green Hairstreak ( Callophrys rubi), 

 Plate XVI., Fig. 8. It is brown above and 

 bright green with a white streak beneath.
