THE ENTOMOLOGIST’S 
WEEKLY INTELLIGENCER.

HINTS FOR OBSERVERS. 
The Smithsonian Institution has issued 
a “ circular in reference to the history of 
North American grasshoppers.” 
“ The grasshoppers of North America,” 
we are informed, “ correspond to the 
locusts of the Old World, which commit 
such ravages in Asia and Africa. The 
term locust is applied in America to a 
widely different inseet.” 
“The Smithsonian Institution, being 
desirous of obtaining aeeurate informa- 
tion respecting the grasshopper tribes of 
North America, calls the attention of its 
friends and correspondents to a number 
of queries relative to this subject, drawn 
up by Mr. P. R. Uhler.” 
These queries, sixty-one in number, 
have struck us as likely to be serviceable 
to those who are engaged in working out 
the economies of other insects, and we 
therefore reprint them for the benefit of 
the entomological public on this side of 
the Atlantic.
