of night, when examined by clay-light, it is . little creature, about three quarters of an inch long, of a dull, earthy brown on the back, the under part tinged with rose colour : the two or three last joints of the body are of a

pale sulphur, from whence the phosphoric

light proceeds. The larva, pupa, and coinplcte female insect, in their general appearance, differ but little front each other; but the luminous brightness is most striking itt the last state, and is displayed or withheld at pleasure, being increased by the motion of the insect, and diminished, or obscured, by either unfolding or contracting the body. This curious property is given to the female glowworm, which is destitute of wings, as a means of attracting the notice of the male, which is a flying insect, and, without this dazzling in

vitation, would be at a loss to discover its

mate in the dark. Dr. Darwin alludes to this beautiful phoenomenon, in the Iblowing lines, addressed to the Nymphs of Fire .

You with light gas the lamps nocturnal feed, That dance and glimmer o'er the marshy mead Shine round Calendula at twilight ii furs, And tip with silver all he saffron flowers Warm, on hr mossy couch, the radiant w'riu Guard from cold dews her Iove-illumin'd form:

Hots icy Garden,
