[Gryllus, or Gryllidte, of English authors]. [The Great Green Grasshopper, with long antennae], .._ »jrêv,--^, _ -feîvisîrsE ,- Z,. fù-;rfmm«, is two inches long, green, without spots ; y^ë^.^^;.^^^^^-^-*^-^-^---—*^*^^8«»^- the ovipositor of the female is straight. „ „„ , . ... Many species of this genus are destitute of wings, or Fig. 92.—L. viridissima. ' ' " ° ' have wing-covers only, but of very small size. [The species of this genus, or rather, family, have been distributed into a considerable number of generic groups by Thunberg, Serville, Latreille, Burmeister, and others, founded upon external variations of form.] The others have the antennaj filiform and cylindric, sword-shaped, or thickened at the tips, and as long as the head and thorax ; the wings and mng-covers are roof-shaped when inactive, and the tarsi are 3-jointed. The tonguelet, in the majority, has only two divisions; the ocelli are three in number, and constantly distinct ; the mandibles much toothed ; the abdomen conical, and compressed at the sides. They leap with much more energy than the preceding, and have a much longer sustained flight. They feed upon vegetables with great voracity. They may be united into a single genus, that of AcRYDiuM, Geoffr.,— \\1iich [lias been greatly divided into genera and subgenera by Serville, Burmeister, and Tliunbe
