and more distinct than in the male, and a ! 

 dentated white band traversing all the ! 

 wings, between the ocelli, and the fulvous 

 band : cilia brown. Caterpillar green, hairy, | 

 with whitish tubercles ; a reddish-brown 

 dorsal line, edged with white, another on 

 the sides, and some oblique stripes of the 

 same ; head and true legs brown : it feeds 

 on common food and saintfoin. Chrysalis 

 at first green, afterwards brown. 



POLYOMMATUS ARioN ; or Aniox BUT- 

 TERFLY. This insect is considered one of 

 great rarity, and is usually found on com- 

 mons and pastures early in July. Wings 

 above brown, with a blue disc, or blue with 

 a brown margin posteriorly ; anterior with 

 a central transverse black spot, behind which 

 is an undulated row of black bars, disposed 

 longitudinally ; the posterior wings have 

 some obsolete ocelli towards the hinder 

 margin : beneath, dusky ash-colour ; the 

 anterior wings with about eight ocelli, form- 

 ing an undulated band near the hinder 

 margin, all with a black pupil and white 



are given of its having been met with both 

 in the north and west of England. It fre- 

 quents meadows and grassy places, like its

iris : on the hinder margin are two rows of 

 black wedge-shaped spots, with a pale dot 

 attached to each ; the cilia white, with brown 

 bars beneath : the posterior wings with the 

 base blue-green, and having an angulated 

 row of four ocellated dots, followed by a 

 transverse discoidal crescent, and then by 



an interrupted angulated and waved band, 

 consisting of eight ocelli, the inner but one 



I being frequently double ; beyond this, on 

 the margin, are two rows of lunulated dots : 

 cilia as in the anterior wings. Body dusky, 



| with bluish hairs above, hoary beneath : 

 antennas black, aunulated with white. It 

 is occasionally caught in the vicinities of 

 Dover, Winchester, and Bath. 



POLYOMMATUS ARTAXERXES ; or SCOTCH 

 ARGUS BUTTERFLY. This unassuming 

 species of the papilionaceous tribe was 

 until lately supposed to be peculiar to 

 Scotland ; but it is no longer so, as instances 



congeners, and makes its appearance first 

 in June, and again in August. The wings 

 above are in both sexes black brown, with a 

 discoidal white spot on the anterior, and 

 sometimes on the posterior ; they have also 

 an orange -coloured band ; fringe white, 

 brown at the base : beneath, the anterior 

 wings have a central white spot, between 

 which and the posterior margin are five 

 similar spots, followed by a broad orange- 

 coloured band, terminating externally in a 

 white spot with a black pupil, and interiorly 

 in a series of black and white crescents : on 

 the margin of the posterior wings this band 

 is continued ; there is a large white blotch 

 on its interior edge, and between it and the 

 base of the wing are several scattered white 

 spots. Like its congeners, however, it is 

 subject to considerable variations. 



POLYOMMATUS CORYDON ; or CHALK HILL 

 BLUE BUTTERFLY. In all chalky dis- 

 tricts this pretty butterfly abounds, espe- 

 cially on the downs, and under the clift's, 

 near Dover ; in various parts of the Isle of 

 Wight, on the beds of chalk round Win- 

 chester ; and in many other similar situa- 

 tions. The wings above are of a rich pale 

 silvery-blue, with the hinder margin and 

 nervures dusky, and cilia white : the pos- 

 terior wings with five sub-ocellated spots in 

 the hinder margin : beneath, the anterior 

 wings are whitish, ocellated, and usually 

 with two or three spots towards the base of 

 the wing : beyond the undulated band of 

 ocelli is an interrupted brown streak, be- 

 tween which and the hinder margin is a 

 series of sub-ocellated dots, with a whitish 

 circle : posterior wings cinereous, greenish- 

 blue at the base, with four ocellated spots 

 at the base, and eight forming an angulated 

 band behind the middle : the pupils black, 

 with a white iris ; in the centre of the wing, 

 between the bands, is a white sub-triangular 

 spot ; and on the hinder margin is a series of 

 ocellated black spots, with a white iris, 

 marked internally with orange ; which series 

 is connected by a pure white oblong patch to 

 the external ocellated band : cilia white. In 

 the female, the fulvous-orange spots on the 

 hinder margin of all the wings are more 

 distinct than in the male, and the cilia arc 

 browner. 



POLYOMMATUS ADONIS ; OTCLIFDEN BLUE 

 BUTTERFLY. This truly beautiful insect 

 is extremely local, but still very plenti- 

 ful on all the Sussex downs and Kentish
