tion, devoting whole fields of our most valuable esculent to its 
uses—at least, it has not hesitated to appropriate them thus—and 
adorning it with our most brilliant pigments. But having, in ac¬ 
cordance with the old adage, “ Welcomed the coming,” we are 
now quite willing to u speed the parting guest.” To tell the plain 
truth, our visitors from Colorado, with their enormous families, 
have got to be an intolerable bore. In no former years have the 
complaints of their depredations been so loud and so universal 5 
the hot and dry summer having evidently been favorable to their 
multiplication. 
I have heard of a few localities, both in Iowa and Illinois,where 
these insects were numerous last year, but have nearly or quite 
disappeared this year, giving us a gleam of hope for the future. 
But such cases, the past season, I believe to have been rare and 
exceptional, and we have reason to be not a little suspicious that 
our visitors from the Rocky Mountain country will prove to be¬ 
long to that class of friends alluded to by the poet in the following 
stanza: 
“ I do not tremble when I meet 
The stoutest of mv foes: 
* 7 
But Heaven defend my from the friend 
Who comes—but never gees.” 
In our dilemma, the question then is, what can we do to expe¬ 
dite their departure ? 
In the first place mother Nature has come to our relief, to a cer¬ 
tain extent, and has sent a host of assistants to aid us in the task. 
We can now enumerate at least nineteen different kinds of insects 
which prey upon the Colorado Potato-beetle. We give their 
names below, numbering for the purpose of reference:
