THE LyccBuidcV' are a large family of 

 small or moderate-sized butterflies 

 which are distributed in all parts 

 of the world. They may be roughly 

 classified into three groups, which we may 

 here designate by 

 their popular nam.es, 

 to wit, the " Blues." 

 the " Coppers " and 

 the " Hairstreaks." 

 Of these latter we 

 have in Britain five 

 species, two of which 

 are rare. Superficially, 

 all the species bear a 

 considerable r e s e m- 

 blance one to another, 

 a characteristic fea- 

 ture being a more or 

 less developed " tail " 

 near the anal angle 

 of the hind-wing, al- 

 though this is not 

 pronounced in the 

 Green H a i r s t r e a k, 

 which also differs from 

 the other species in 

 not possessing distinct 

 whitish streaks on 

 the underside of the 

 wings. These butter^ 

 flies agree with other 

 members of their fam- 

 ily in the possession of 

 six perfect legs — a 

 point, by the way, of 

 considerable import- 

 ance, seeing that in 

 certain famihes of but- 

 terflies only four legs 

 are sufficiently dev'el- 

 oped for walking. 



The particular Hair- 

 streak which is to

form the subject of this article is, as my 

 title indicates, especially associated with 

 the oak. Indeed, of all the British butter- 

 flies it is the only one whose caterpillars 

 feed exclusively upon the leaves of this
