There is no doubt that all these figures belong to one species; though
differing, not only in size, but structure. Antennæ light red brown. Head
thin, rounded, margined, and of a green golden colour; some (which are
evidently males) being furnished with a smooth, round, black horn, almost
as long as the thorax, and inclining backwards; others have only a small
tubercle in the place of the horn; and others have a small horn, about
one-fourth the length of the first mentioned, as in Fig. IV. Thorax
{73}next the head golden green; behind and on the upper part is golden
red, and margined, rough and shagreened. In the horned specimens this
part terminates on each side the posterior margin in a projecting angle,
which is more or less conspicuous, in proportion as the horn is long or
short. Those which are quite hornless, as Fig. V., are entirely destitute
of these angulated risings, having the thorax rounded, but in its front a
small black protuberance or swelling is seen. Elytra golden green,
inclining to a blue, and very much channelled, with small striæ placed
between others of larger size, extending almost even with the anus.
Abdomen black, the sides shining green. Anterior femora and tibiæ black
and hairy; the latter very strong and dentated, having a long moveable
spine fixed on the inner edge of each, extending somewhat beyond the
tarsi, which are very short and small. Intermediate and posterior thighs
shining golden green, broad and strong. Tibiæ black, with two spines (one
very long) at the tips. Tarsi five-jointed, ungues single, and not
divided as most insects have them. Scutellum obsolete.
