Fabricius suggests that this insect may be a possible variety 
(nuper declaratuin) of his L. I'egalis; but that species is abundantly 
distinct, not only in its markings, but also in its longitudinally 
multi-striated elytra and the rounded humeral angles. 
The Fabrician description abstracted above accords exactly with 
a specimen from Guinea, received by the E.ev. F. W, Hope from 
Mr. Westerniann, whose residence at Copenhagen enables him to 
determine the identity of those Fabrician species which were 
described, (as was the case with the one befoi'o us,) from the 
collection of M. Sehestedt. This specimen is represented in my 
pi 86, fig. 3. Tt is a male, and has the mandibles armed with a 
strong, rather deflexed spine in front near the base, the outside of 
the mandibles being green, and the remainder black. The middle 
of the face and labrum are fulvous, the former with two rather 
broad green bars extending from the base of the antennoe to the 
mouth; the sides of the head behind the eyes are also green ; there 
is a diamond-shaped fulvous patch on the middle of the crown, 
the hind part of the head being green; the prothorax is fulvous, 
with a slender green transverse fascia across the anterior part, and 
the hind part of the prothorax, including the spaces behind the 
lateral teeth, are also green. The humeral angles of the elytra 
are very prominent, and angularly truncate; the anterior green 
fascia is, as it were, divided into two parts by a slaty-green stripe, 
and the three green spots forming the central curved fascia are 
margined with dark slaty green ; besides the spot in the middle 
of each elytron towards the extremity, there is a little green patch 
next the suture, which is itself also green. The feet are green, 
with the undersides more golden. 
I possess two beautiful varieties of this species, one in which the 
green markings are of a bluer hue, and separated from each other 
by, or margined with, black lines ; and the other in which the 
ground colour of the insect is of a browner fulvous colour, and the
