[Illustration: Fig. 101.--Issus Coleoptratus.] The _Cicadas_ are improperly called "Locusts" both in America and Australia, on account of the chirping noise which they perpetually keep up in the woods, both day and night. _Family 2, Fugloridæ._--This family includes the Lantern Flies and Candle Flies, which are remarkable for their large size, bright colours, and strange forms. They are almost all exotic insects. [Illustration: Fig. 102.--Tettigometra Virescens (Mag.)] The largest species is found in South America, and is called the Great Lantern Fly (_Fulgora laternaria_), measuring nearly three inches in length, and over four inches in expanse of the wings. [Illustration: Fig. 103.--Pœciloptera Phalænoides (Mag.)] The Chinese Lantern Fly (_Fulgora candelaria_) has a red body, the fore wings being greenish with yellow spots, the hind wings orange colour with black tips. [Illustration: Fig. 104.--Membracis Foliata (Mag.)] _Cixius nervosus_ is found in the British Isles, chiefly on alders. It measures about a quarter of an inch in length, and in colour is black with yellow legs, and transparent wings dotted with brown. _Family 3, Membracidæ._--This family is chiefly remarkable for the fantastic shapes assumed by the prothorax. Most of the species are inhabitants of America, where they occur in wonderful abundance and variety. [Illustration: Fig. 105.--Smilia Fasciata (Mag.)] A common species, _Centrotus cornutus_, is found in the British Isles and over the greater part of Europe. It is rather over a quarter of an inch long, black, with a pair of upright horns on the prothorax. Another common European and British species (_Gargara genistæ_) is smaller than the preceding, and has no horns on the prothorax. [Illustration: Fig. 106.--Œda Inflata (Mag.)] _Family 4, Cercopidæ._--The "Froghoppers" and "Cuckoo-spits" belong to this family. They are chiefly small insects found among grass and bushes in the summer. [Illustration: Fig. 107.--Physoplia Nigrata (Mag.)] A very common species in this country is the common Cuckoo-spit (_Aphrophora spumaria_), which is about a quarter of an inch in length, and of a yellowish-grey colour. This insect can make a prodigious leap in proportion to its size. It is said to sometimes spring to a distance of two yards. Its yellow _larvæ_ may often be seen on grass and low plants enveloped in a mass of froth, which has given rise to the name of "Cuckoo-spit." [Illustration: Fig. 108.--Hypsauchenia Westwoodii (Mag.)] _Family 5, Tettigonidæ._--These insects are exceedingly numerous, and are often remarkably elegant in form. They are mostly inhabitants of America, where some three or four hundred species have been described, but in England we have an exceedingly pretty species (_Tettigonia viridis_), which is common in damp meadows.
