Lamiarize and the Lepturetee, will terminate the division of the 
Cerambycini. 
Their palpi are almost filiform, the last joint almost cylindrical, and 
‘somewhat attenuated towards the base; their thorax is usually smooth, 
or but slightly uneven, without acute tubercles, and becomes widened 
posteriorly, or presents the form of a trapezium or truncated cone, as 
in the last tribe of this family; the abdomen in the greater number is 
almost in the form of a reversed triangle, and the elytra are truncated 
at the extremity. 
These Insects form four genera, 
Disticnocera, Kerby, 
Where the antenne of the males are gradually dilated towards the 
extremity, and their joints, from the third, are forked or divided into 
two branches at the end *. 
TMESISTERNtS, Lat., 
Where the antenne are simple, setaceous, and longer than the body; 
the thorax is lobate posteriorly, and the presternum prolonged be- 
hind, truncated, and received into the emargination of the mesos- 
ternum}. 
Tracocervs, De7., 
Where there is no presternal projection; the antenne are filiform, a 
little shorter than the body, and somewhat serrated; the thorax is 
unequal, slightly sinuous laterally, and the elytra form a large square f. 
Leprocera, Dey., 
Where the presternal projection is also-wanting; but the antennz 
are setaceous and much longer than the males; the thorax is smooth, 
and in the form of a truncated cone, and the abdomen and the elytra 
are almost triangular §. 
The Longicornes of our third tribe, that of the Lamarz, are dis- 
tinguished by their vertical head, and by their palpi, which are filiform 
or hardly larger at the extremity, and terminated by a joint more or 
less ovoid and tapering to a point. The outer lobe of the maxille is 
slightly narrowed at the end, and curved on the inner division. The 
antennz are most frequently setaceous and simple, and the thorax, 
exclusive of the lateral tubercles or spines, is nearly of an equal width
