THE SERRICOKN BEETLES. 45. brown ; the surface is smooth and polished ; the upper jaws of the male are long, curved like , F1 20 a sickle, and furnished internally beyond the middle with a little tooth; those of the female are much shorter, and also toothed ; the head of the male is broad and smooth, that of the other sex nar- rower and rough with punctures. The body of this beetle measures from one inch to one inch and a quarter, exclusive of the jaws. The time of its appearance is in July and the beginning of Au- gust. The grubs live in the trunks and roots of various kinds of trees, but particularly in those of old apple-trees, willows, and oaks. All the foregoing beetles have, by some naturalists, been gathered into a single tribe, called lamelli- corn or leaf-horned beetles, on account of the leaf-like joints wherewith the end of their antennas is provided. The beetles next to be described have been brought to- gether into one great tribe, named serricorn or saw-horned beetles, because the tips of the joints of their antennae usually project more or less on the inside, somewhat like the teeth of a saw. The beetles belonging to the family Btjpkestidjs, or the Buprestians, have antennas of this kind. The Bwpres- tis of the ancients, as its name signifies in Greek, was a poi- sonous insect, which, being swallowed with grass by grazing cattle, produced a violent inflammation, and such a degree of swelling as to cause the cattle to burst. Linnaeus, how- ever, unfortunately applied this name to the insects of the above-mentioned family, none of which are poisonous to ani- mals, and are rarely, if ever, found upon the grass. It is in allusion to the original signification of the word Bwprestis, that popular English writers on natural history sometimes give the name of burncow to the harmless Buprestians ; while.
