Fig. 88. 
This singular genus is at once known by the narrow 
conical head, which is longer than the thorax ; and 
by the antennse, which are ensiform and prismatic, 
as long as the head and thorax taken together, multi- 
articulate, and inserted between the eyes at the ex- 
tremity of the head ; the body long and narrow ; legs 
slender and lengthened. The species, which are not 
numerous, and by no means accurately distinguished, 
are peculiar to warm climates, and we know r scarcely 
any thing of their manners. The figure referred to 
above, may possibly represent a variety of T. Nasutus , 
although Stoll, from whom we have copied it, regards 
it as distinct. The thorax and tegmina are brownish 
yellow, the latter with a crenated white ray along each ; 
abdomen marked with yellow and black spots ; legs 
brown. Fig. 3d, of the_ same Plate, represents a 
species named T . brasiliensis by Drury. It is closely 
allied to T. nasutus as well as T. conicus. The teg- 
mina are pale fulvous, with a green stripe along the 
centre of each, irregularly indented on the hinder edge 
with black ; wings transparent, the basal portion 
tinged with a delicate and beautiful red. Its habitat 
is Rio Janeiro, Brazil, &c.
