in zoology, a genus of insects belonging to the order of coleoptera. The antennae are shaped like bracelets, and thicker on the outside; and neither the breast nor the elytra are margined. There are no less than 122 species enumerated by Linnaeus, principally distinguished by differences in their colour. They are to be found almost everywhere, in woods, gardens, &c. Their progressive motion is slow; and some when caught emit an oily liquor of a disagreeable smell. The glittering colours with which several species of chrysoleleae are adorned, and which seem to exhibit the brilliancy of gold and copper, have occasioned their bearing that pompous name. The larvae of these insects have in general an oval body, rather oblong and soft; on the fore-part of which are situated six feet, which are fealy, as is also the head. They prey upon the substance of leaves, rejecting the fibrous part. Those of the leaping chrysoleleae infest the cotyledons and tender leaves of plants. Of this genus is that very pernicious insect called by the country people the turnip fly, which infests turnips and many crops in the garden, destroying often whole fields while in their feeding leaves. In very hot summers they abound to an amazing degree, and, as you walk in a field or in a garden, make a patterning like rain, by jumping on the leaves of the turnips or cabbages. See Plate CXLIX.
