Species description notes from Insect. Rhynchota.:
Stal treated this species as a synonym of T. grossa, Fabr. The type of the Fabrician species, however, is in the Banksian collection contained in the British Museum, and is very distinct, the opercula being large and rounded.
The figure given in the Encyclopedic Methodique is, like Stal’s, useless for any practical purpose. Among the habitats of this wide-ranging species is that given by Walker 2, ” West coast of America,” which, as before remarked in connexion with other species, seems clearly to refer to Central America. The forms inhabiting this region (of which a Guatemalan specimen is figured) appear to be somewhat smaller than more southern specimens, or do not exhibit the gigantic specimens which are frequently and commonly received from the southern portion of the Neotropical Region.
Mr. Gervase F. Mathew (Ent. Mo. Mag. xi. p. 175) gives some interesting details relating to this insect as observed at Tobago. As regards its powers of stridulation he writes of a ” tropical afternoon: ” — ” Suddenly, from right above, you hear one or two hoarse, monotonous cries something like the croak of a tree-frog, and, looking upwards, wonder what it can be. But wait a moment ; this is merely a signal ; for the next minute everywhere above and around you these croaks are repeated in rapid and increasing succession until they merge into a long shrill whistle almost exactly similar to the whistle of a first-rate locomotive ; this continues for nearly half a minute, and then abruptly terminates.” ” Presently similar cries will be heard in the far distance, as if in reply to those which have just died away overhead. The whistling pierces one’s ears to such a degree that its vibrations can be felt long after it has ceased.”
Mr. Mathew describes this species as frequenting trees growing in ravines where the soil is generally soft and damp, in which their larvae and pupae find no difficulty in burrowing. ” When the latter are full-grown and ready for their last transformation, they emerge from the ground and crawl about four or five feet up the trunk of a tree, when they firmly fix themselves to the bark by means of their powerfully hooked fore tibiae.” ” The flight of the mature Cicada is abrupt, rapid, and by no means graceful ; and it does not appear to have the power of controlling itself when on the wing ; for I have often seen it fly in an insane manner against the trunk of a tree, a branch, or any other object that might be in its line of flight; and when it has performed its journey without any accident, it alights abruptly and awkwardly. As a rule, however, it does not attempt to fly to any great distance at a time.”
