The antenna; are comparatively rather narrow in this species; they are nearly two-thirds of the length of the
elytra, which latter are three and one-third times the length of the prothorax. The clava of the antennse is
broadest in the middle, at the fifth joint; the width of the sixth joint equals the length of the sixth
seventh, eighth, and half of the ninth joints united together; the length of the tenth joint equals that of the
seventli, eighth, and half of the ninth joints together.

Tlie antenuíe are equal to three-quarters of the elj-t.ra in length, and the length of the elytra is twice their
breadth. The length of the antenna) (including the basal joint) is four times theii- width, which is nearly
nmform. The width of the seventh joint is nearly equal to the length of the ninth and tenth joints united •
the tenth jomt is as long as the ninth, eighth, and one-fourth of the seventh joints united.

The antenna; are equal to two-thirds of the elytra in length; the last joint is just the length of the three
preceding joints united together; the basal joint is broader than long; the breadth of the sixth joint equals

The length of the antenna; equals that of the head, prothorax, and twice the scutellum; that of the
terminal joint equals the seventh, eighth, and ninth joints; the breadth of the antenna; in the middle of
the clava nearly equals one-third of their entire length. The length of the elytra is nearly thrice that of the
prothorax.
I am indebted to Dr. Howitt for the specimen of this species here described ; it is given as distinct from
J. MacLeayii on his authority, he having compared it with the type specimen of that species in Mr. MaoLeay's

The antenna; are equal in length to the head, thorax, and scutellum ; the terminal joint is scarcely semicircular,
being only equal to the two preceding in length. The basal joint is deeply emarginate for the reception
of the second joint ; the elytra are thrice the length of the prothorax, and their width nearly equals half their
length. The width of the middle part of the clava of the antenna; is equal to the length of five of its intermediate
joints united.
