of burnished steel ; elytra tridentate at tbe extremity, cupreous 
in the middle, bronze-green on the margin, with impressed 
puncta, and elevated lines and rugae. Cayenne. 
B. ajftnis, Fab.; B. chrysostigma, Oliv., Ib., VI, 54. Bronze 
above, brilliant cupreous beneath ; elytra serrated at the point, 
with three elevated longitudinal lines, and two golden impres- 
sions on each. France. 
B. viridis, L. ; Oliv,, Ib., XI, 127- About two lines and a 
half long ; linear ; bronze-green ; elytra entire and dotted. On 
the trees in France (a). 
Fabricius has separated from the true Buprestides those in which 
the body is shorter, wider in proportion, and almost triangular ; the 
front concave, thorax transversal and lobate posteriorly ; where the 
tarsi are very short and the pellets broad. The five last joints only 
of the antennae here form the teeth of the saw, the preceding ones, 
with the exception of the two first, being small, almost graiiose, or 
obconical; the two first are much stouter. These species compose 
the genus Trachys *, one of which is 
B. minuta, L, ; Oliv., Ib., II. 14. Black underneath; cupre- 
ous-brown above ; middle of the front indented ; posterior margin 
of the thorax sinuous ; undulated whitish streaks, formed by 
transverse hairs, on the elytra. Common on the Hazel, on the 
leaves of which it feeds. 
Aphanisticus, Lat. 
The antennae stiddenly terminated by a clavate, oblong, compressed, 
and slightly serrated club, formed by the four last joints ; last joint 
of the palpi somewhat thicker and almost oval ; space between the 
eyes excavated as in Trachys. 
Two or three species are known, all linear, and very small f. 
Sometimes the antennae are strongly pectinated, on one side, in the 
males, and deeply securiform in the females ; the joints of the tarsi 
are almost cylindrical and entire, the antennae terminated by one 
much thicker than those that precede it, and nearly globular. The 
jaws terminate in a single lobe. 
Melasis, Oliv. 
The body cylindrical, and the posterior angle of the thorax pro- 
longed into an acute tooth, characters, which, in those drawn from
