Fab., as a family ; and compared with Lepturide, it has certainly stronger claims to 
rank as such, both from its widely extended geographical distribution, and the numerous 
forms included in it. The Lepturide are chiefly confined to a northern latitude, and the 
metropolis of the family is probably North America, or Northern Europe. There are, 
it is true, a few species found in South America; but these recede, according to my 
views, from the type of Lepturide. Stenocorus affects warmer climates, and has not 
yet, I believe, been found in Europe. It is widely dispersed in North and South 
America, and is met with in various parts of the Continent of India and in Java, as 
well as in New Holland. The following table will give a concise view of the Stenoco- 
ride, the family being divided in the first instance into two sections, depending on the 
armature of the antenne.
