Cuvier's animal kingdom : arranged according to its organization cuviersanimalkin00cuvi Year: 1840 Fig. 87.—Forficnla the tonguelet is furcate ; the thorax is plate-like. The second joint of the tarsi is simply dilated beneath, near the tip, or in form of a reversed heart, and not notched. These insects have been very carefully investigated in respect to their internal anatomy, by Messrs. Ramdohr, Posselet, Marcel de Serres, and especially by Léon Dufour, in the Annales des Sci. Nat., vol. xiii. From their anatomical characters they appear to L. Dufour to constitute a distinct order, which he names Labidoures. Mr. Kirby had also previously proposed the name of Dermaptera for them as an order. These insects are very common in damp situations, where they often assemble in troops under stones, and the bark of trees ; they do much injury to the fruits of our gardens, [devouring also the petals of flowers], as well as the bodies of their dead companions, defending themselves with their forceps, of which the form varies according to the sex. It is a vulgar notion that they creep into the ear of sleeping persons ; this, however, is the origin of their French name, Perce-oreille [EngUsh name. Earwig ; German name, Ohrwurni, &c.] [The species has been distributed into a considerable number of subgenera by Leach, Serville, and Burmeister.] Latreille divides them, in a note, into Forficula proper, which has not more than 14 joints to the antennae. Forficula auricularia, is more than half-an-inch long, brown, shiny, with a reddish head, the sides of the thorax grey, and the feet yellow-ochre coloured. The female guards her eggs with much care, as well as her young, for a considerable time. Forficula minor (the small Ear>>ig), is much smaller, and has 11- or 12-jointed antennae ; it forms Leach's genus Labia. Forficesila, Latr., has more than 14 joints to the antennae.
