formed me that they visited his gardens ev ery year, in rather limited 
numbers, but he had never diienuaead them in their larva state. 
Subsequently Dr. Hoy, of Racine, Wis., furnished me with many 
fine specimens. From him I learn that during a brief period of about 
two weeks, they resort in great numbers to the flowers of the garden 
raspberry, (Rubus Idveus), and are seen at no other time. During their 
sojourning they doubtless deposit their eggs ou some species of vegeta 
tion, which affords appropriate food for their larva. Whether their re- 
sort to the flowers of the raspberry is for that purpose, or to obtain f

The Macroglossa I found in Dr. "Hoy? s cabinet, as also in Gov. Far- 
well’s collections at Madison, Wis., and learned that it is proto abe 
seen in different parts of that state. In its habits it is said to resemble 
the Sesia pelasgus. 
From what I have ascertained, I conclude that the Libythea is some- 
times found as far east as Bastin, Mass., but that both it and the Macro- 
glossa belong more appropriately to sections of the prvtees west of Ohio.
