LYCÆNA LYSIMON.
This is the smallest specimen of blue butterfly found in Teneriffe, being not quite one inch in expanse. The female is rather a browner blue than the male. The colouring on the upperside is of a most beautiful uniform blue, all the wings having a margin of brown; and a slight white fringe at the edges. The underside of all the wings is grey, rather freely dotted over with darker spots, encircled by greyish white. It is very commonly found on all grassy fields and lanes, and quantities flutter quickly along the grass-grown streets of Orotava from April to August.
It is not an inhabitant of England, but is found in the south of France, Spain, greater part of Africa, Western Asia, and the East Indies. The caterpillar and chrysalis have not been observed.
