wed out at its base. Legs rather thick, the outer of the two tarsal
claws of the third pair of legs, cleft at the end, anterior tibiae
externally sub-tridentate. Thorax with the sides somewhat angulated and
narrowly margined, rounded behind, but the sides of the posterior margin
are straight, the surface is minutely punctured and covered with brown
hairs, the sternum of the mesothorax is without a spine, or projecting
angle; elytra in some specimens of a rich, lively, metallic, yellowish
green, in other coppery green with the suture and margin dark green, the
surface chagreened and punctured. Underside of the body and legs dark
green, the former covered with ash-grey pubescence, or rather longish
soft hairs.

This insect seems to be one of those links which connect such genera as
Anoplognathus, Amblyterus and Brachysternus, and it is very difficult to
say to which of these genera it is most allied. Professor Burmeister has
begun to eradicate the Phyllophagous genera of Beetles, and from his deep
knowledge of Entomology, and the particular acquaintance which he has
with the principles of general Zoology, as well as the thorough manner in
which he means to go through all the species, much light may soon be
expected to be thrown on the subject; how true is Darwin's remark, made
in speaking of a somewhat anomalous bird, "this, from its varied
relations, although at present offering only difficulties to the
systematic Naturalist, ultimately may assist in revealing the grand
scheme, common to the present and past ages, on which organized beings
have been created." (Journal and Remarks Voyage of Beagle 3 page 112.)

BIPHYLLOCERA, g.n.

Antennae (seemingly) nine-jointed, the first joint long, much thickened
at the end, and furnished with several stiff hairs, the five last are
lamelliform, the lamellae in the male long, and pinnated on one side;
labium deeply grooved in the middle, notched at the tip; palpi with the
terminal joints longest, sub-cylindrical; head moderate; clypeus
separated by a distinct line, basal part slightly hollowed out, as is the
head between the eyes; thorax short; elytra elongate, somewhat rounded on
the lateral edge, truncated at the end; legs slender; tibiae of first
pair anteriorly sub-tridentate, tibiae of second and third pairs with
many spines, claws of posterior tarsi entire, joints of tarsi, slender,
elongate.

In the system this would come at no great distance from the genus Serica,
