dark In-own ; the crown of the liead and back of the pronotum with three slender lines in the middle, which
converge together near the seutellura (wliich is ^vhite) ; the elytra are varied with a nnmber ot dirty whue and
dark-brown lines and obliiine patches, especially a larger diamond-shaped dark-browu spot on the sutm'e before the

DJ3SC1UPTI0N.—The termiual joints of the anteimie have also a very small tuft of hah's within, those
oil the last joint being placed in the middle, so as to give the appearance of there being t-\velve joints.
I n addition to the markings above described tliere is a slender whitish line on each side, which extends
from the eyes to the tip of the elytra, and another in front of each fore-leg ; the sides of the breast and
abdomen ¡re also marked «itli slender lines of the same colour. The fore-legs are long, the tibia;
rather crooked, and the fore tarsi dilated and hairy; the elytra are rounded and simple at the tips.
The presternum is arched, and extends narrowly between the fore cox«, without any promment angle,
the mesosternum forming a very slightly porrected angle. This insect departs from the typical form of
Gnoma, to which genus it is nearly alUed. There are two nndescribed Javanese genera introduced
into De Jean's catalogue, with plumose antenna;; the &st, Imantocera {Cerambyx plumosus, Ohv,), is
much nearer to Lamia than the present insect ; the other is named Psectrocera scopulicornis, Dej. It
is impossible for me to determine whether it be identical with the insect here figured.

the lower part of each eye; the upper part of the head and the pronotum are marked with three
lono-itudinal white hnes; the middle one terminating in the scuteUum, which is wliite, and the side
onet in a short oblique white dash on the shoulders of the elytra, which latter are truncate at the tips,
the angles of the incision being slightly produced. The presternum is simple, but the mesosternum is
porrected and forms a right angle when seen in profile.
