Westwood, there are found in the south of Europe three 
species; in South America, twenty species; in North 
America, three species; in Asia, forty species; in Austra- 
lia, twenty-seven species; and in Africa, two species. 
Mr. Say, in his American Entomology, has given a good 
illustration cf the Spectrum femoratum, in plate 37, and of 
. the Spectrum vittatum, in plate 38, to which I refer the 
reader. 
It is much to be regretted that death has taken from us 
this highly distinguished American naturalist; but his 
works are left behind him, and will insure him long re- 
membrance among all lovers of Science and Nature. Mr. 
Say accompanied Major Long in his exploring expedition 
to the Rocky Mountains many years ago, and afterward 
traveled with Mr. M‘Clure through Florida and other coun- 
tries. He published his American Entomology in 1824, in 
three volumes, with fifty-four very-well executed colored 
plates, and is the author of a great number of valuable ar- 
ticles contained in the Transactions of several of the learned 
societies of the Union. Thomas Say was a member of the 
Society of Friends, Curator of the American Philosophical 
Society, Professor of Natural History in the University of 
Pennsylvania, and of Zoology in the Philadelphia Museum.
