[Numerous very small species, found by sweeping grass at the sides of roads, commons, &c. Some of the species occasionally have the wing-covers only partially developed. These constitute the genus Criomorphns, Curtis.] Derbe, Fabr., are unknown to me, but I presume they come near the preceding insects, and especially to Anotia. In the terminal Cicadariae the antennae are inserted between the eyes. These compose the genus CiCADELLA (or the Cicada Ranatree, Linn.),^ Which may be thus divided :— We commence with the species ?which, with the exception of a small number, (Ledra,) formerly com- posed the genus Membracis of Fabricius. The head is very much deflexed, or low in front, and pro- longed into an obtuse point under the form of a clypeus, more or less semicircular. The antennae are always very small, terminated by an inarticulate seta, and inserted in a cavity under the margins of the head ; the prothorax is sometimes dilated, and horned on each side, and prolonged behind into a simple or composite horn, and sometimes it is elevated longitudinally down the back, comp
