LYCÆNA ASTRARCHE v. ÆSTIVA.
Plate II.—Fig. 6.
A small dark copper, the expanse of wings being about one inch, or rather more. It is not found in England. On the upperside on all the wings there is a marginal band of bright copper, the fore-wings have a black spot about the centre of each. A fringe of white edges all the four wings. The under widely differs from the upper side in colouring and markings. The ground colour is light grey, freely dotted over with black spots encircled by white. All four wings have the same bright marginal copper band as seen on the upper side. The antennæ are black or dark brown, finely dotted with white. It is somewhat rarely found in fields and barrancos on high ground, but may be met with in larger quantities in the pine forests. The time of its appearance is from April to September. When comparing the Teneriffe specimen of this butterfly with those of other countries at South Kensington, it was noticed that the marginal copper band was broader on the Teneriffe specimen, and it may be possible that it should be reckoned as a new variety.
