CHRYSOPHANUS CHRYSEIS.--The PURPLE-EDGED COPPER Butterfly.--As this species has been admitted by that very careful and accurate entomologist, Mr. Stainton, into his "Manual," I cannot refuse it a place here, though, from all the information I can gain, its only claim to the name of "British" rests on a tradition of its having been taken a long time ago in Ashdown Forest, Sussex; and since then, by a _dealer_, in Epping Forest. It is a beautiful insect, coppery red, bordered with changeable purple, and I should be glad to see it fairly established in our lists. * * * * * POLYOMMATUS BÆTICUS.--The LONG-TAILED BLUE.--This Butterfly has been long known, as a _southern_ insect, with a very wide range of distribution, abounding in the south of Europe and thence extending into India, Java, &c. Then last year it was seen in {173} Guernsey, and in August of the same year an individual was actually captured in this country, the scene of the event being somewhere on the chalk downs in the neighbourhood of Brighton, and the fortunate captor being Mr. McArthur, of that town. My friend and neighbour, Dr. Allchin, of Bayswater, was on the spot at the time, and saw the insect shortly after its capture. The _butterfly_, which on the upper side has somewhat of the aspect of a female "Common Blue," will be at once recognised by its _long tail-like appendages to the hind wings_. Beneath, its plan of colouring is totally distinct from that of any of our native "Blues" (_Polyommati_), being destitute of the numerous little eye-like spots, which are replaced by bands of fawn colour and white; but at the lower angle of the hind wings are two spots of glittering metallic green, reminding one, on a small scale, of the "eye" of a peacock's feather. The habits of the insect are those of our Common Blues--skipping about over grassy places, and for a Common Blue it would on the wing be readily mistaken. Collectors will in the coming season doubtless search the south coast district thoroughly, and many a Common Blue will be apprehended on suspicion. Should our little friend _Bæticus_ continue his northward progress (as we have some reason to hope he may), we may find him regularly enrolled on the native lists, and gracing the ranks of that select little company entitled "Our British Butterflies." * * * * * {175} REFERENCES TO PLATES.
