BRITISH BUTTERFLIES. 



length of the costa. The wing-rays are black 

 towards the hind margin ; the fringe is snowy 

 white, with a black spot opposite the end of 

 every wing-ray that is, five in the fore wings 

 and seven in the hind wings. The upper side 

 in the female is smoky brown, occasionally 

 with blue reflections, and having a series of 

 spots, more or less distinct, parallel with the 

 hind margin ; these spots have a somewhat 

 compound character, the upper border being 

 orange, the centre black, and the lower border 

 white ; on the fore wings is a transverse 

 linear discoidal spot, black with whitish mar- 

 gin, but always faiut and indistinct. The 

 under side is grayish brown in Loth sexes ; all 

 the wiugs have a transverse median discoidal 

 spot in the fore wings ; this is black with 

 white circumscription ; in the hind wings it is 

 white, with a very slender black median line ; 

 on the fore wings are nine other black spots, 

 and on the hind wings eleven, all of which 

 have a white circumscription ; there is also a 

 series of compound spots parallel with the 

 hixid margin; the centre of each is orange, 

 with a black mark above and below the 

 orange, and a white circumscription ; a sub- 

 median shapeless white blotch extends from 

 near the middle of the hind wing nearly to 

 its hind margin. 



LIFE HISTORY. Fabricius describes the 

 caterpillar as of a green colour, and as having 

 dorsal series of fulvous spots. Freyer some- 

 what improves this brief description, by fixing 

 the number of spots at twelve in each series, 

 of which there are two ; and adds that there 

 is a yellow stripe on each side. It feeds on 

 leguminous plants. I regret my inability to 

 give any more information respecting an 

 insect that is in every collection. 



TIME OF APPEARANCE. I have never 

 found the caterpillar or chrysalis. The per- 

 fect insect is on the wing in May or June. 



LOCALITIES. Unknown in Ireland, Scot- 

 land, or the Isle of Man. In England it is 

 a southern species, and almost peculiar to the 

 chalk. I give a few localities.

 cuttings, local but abundant W. 0. Ham-

 thousands have been taken in this and 

 some neighbouring localities for the unworthy 

 purpose of making butterfly pictures. E.

44. CHALK-HILL BLUE. In the male the 

 wings are of a pale silvery blue, gradually 

 shading off to smoky black towards the hind 

 margin, where the black forms a hind-mar- 

 giual band in the fore wings ; there is a 

 slender white Hue along the costal margin, 

 and within this is a black line not very 

 distinct or clearly defined ; the wing-cases 

 also are black towards the margin : in the
