zoology, a genus of insects belong- ing to the order of coleoptera. The antennae are falcate, and as long as the thorax: The head is half drawn back within the thorax; to which may be added, that the antennae are ferrated: The mouth is armed with jaws, and furnished with palpi: The elytra are margined, and cover the abdomen; and the tarsi have five articulations: The feet are saltatorial. There are 27 species of this insect, most of them natives of the Indies. The French have given the name of Richard to this genus, on account of the beautiful rich colours with which most of the insects belonging to it are adorned. Insects of this genus are not common in England. They are of the richest splendor; and some appear, when alive, to be united in colour with the re- fulgent particles of emeralds, rubies, diamonds, and gold. Applied to the microscope, the splendor is so great as to dazzle the eye. The guttata is one of the most oblong species. The whole body is green and gold, with a bluish cast underneath; but what distin- guishes it, are four white dents or depressed spots that are seen upon the elytra, two upon each. One of those dots is on the outward rim of the elytron, about the middle of it, near the abdomen, and is the larger one. The other is on the inner edge, close to the future, about three-fourths of that future downwards, and ex- actly opposite its fellow on the other elytron. This latter one is the smaller. The whole upper part of the insect, viewed through a glass, appears finely dotted. This species has been found in timber- yards.
