GENERIC CHARACTER. 
Head vertical ; labrum very distinct; antenna setaceous, 
as long, or longer than the body, composed of ten joints, 
and inserted in a niche in the front of the eyes; palpi 
filiform, the Jast joint oblong-ovate. 
Thorax cylindric, the sides frequently with one tubercle. 
The genera Saperda and Lamia of Fabricius have been 
considered by Latreille and Illiger as constituting but one 
genus, the parts of the mouth being found to be exactly 
similar ; and to this genus they have retained the title of 
Lamia. Some few of the Saperda, however, have eleven 
joints in the antenna, and these I have considered as 
forming a distinct genus, to which the name Saperda may 
be continued. The Cerambyx lineato-collis of Marsham, 
is the only indigenous species of this genus Saperda. 
Of the economy and mode of Jife of this genus little or 
‘nothing more is known, than that the caterpillars live in 
the bodies of trees, which they perforate and destroy.
