i5C BRITISH BUTTERFLIES. 



Various reports of its capture, during the last two 01 

 three years, have been published ; but they all seem tc 

 require confirmation. 



This butterfly is now generally considered to be a 

 large local variety of the continental one called Hippo- 

 Acs, with which it closely agrees in its markings. 



THE BLUES. (Genus Polyommatus.} 



WE now arrive at a numerous genus of elegant and 

 lively little insects, collectively known as the " Blues," 

 though some of them are not blue at all. In their 

 manners, and the localities they inhabit, there is so 

 much in common, that one description of these will 

 answer for nearly every one of them ; so that my small 

 available space will be in great part devoted to pointing 

 out the marks of distinction between the various species, 

 ten in number, several of them closely resembling 

 others in general appearance, and requiring some care 

 in their discrimination. 



Their caterpillars, which are wood-louse shaped, or 

 onisciform, generally feed on low plants, chiefly of the 

 papilionaceous order; and the butterflies are found in 

 ary maadows, on downs, and in open heathy places. 

 The first species, P. Argiolus, is, however, an exception 

 '-o the ibove, both in its food and haunts.
