Our correspondent in Union Parish, Louisiana, describes an insect 
- feeding upon the potato, which he supposes to be a larva of the D. decem- 
lineata, but his description is not sufficiently accurate to distinguish 
it from another species, D. juncta. It is a broad, stumpy worm, nearly 
as broad as long, head, black ; color, reddish brown, with black spots ex- 
tending along the sides of the body. 
In Randolph, West Virginia, the beetles were quite numerous, being 
picked off the vines. In Braxton, Barlow, Cabell, Marion, and Morgan, 
they were very destructive. They were also present in Doddridge and 
Kanawha, in the latter of which they were making their first appear- 
ance. In many cases they were effectually resisted by the farmers. Our 
correspondent in Tyler speaks of a species of potato-bug but little 
known and very destructive. Some farmers sprinkled lime on the vines, 
and others turned in their chickens. He would confer a favor by send- 
ing a specimen to the Department. Six counties in Kentucky report 
the presence of this insect. In Spencer a third of the potato-crop was. 
destroyed, but in Henry, Livingston, Anderson, Fayette, and Shelby, 
the losses were lighter. The ravages of the beetle were here successfully 
resisted either by sprinkling Paris-green upon the vines or by shaking 
them off into vessels and destroying them wholesale. In Henry the 
lady bug (Coccinella) destroyed the eggs of the beetles in great numbers. 
North of the Ohio River this insect is reported in every direction. In 
Ohio, the destruction was mostly in the northern counties, though the 
beetles were threatening in Highland, in the southwest. In Washing- 
ton and Meigs, in the southeast, fear of the pest had greatly restricted 
potato-planting and hence the insect had but little to feed upon. In 
Morrow the crop was cut down one-half; in Franklin, 20 per cent. in 
spite of strenuous resistance; in Trumbull, the entire crop was threat- 
ened; in Logan, the beetles re-appeared in apparently undiminished 
numbers after every effort for their destruction. Great havoe is also 
reported in Stark; some Swiss residents of this county state that this 
beetle is known in Switzerland. In Mahoning, Medina, Portage, Geau- 
ga, Marion, and Noble the insect was more or less injurious. In many 
cases it was destroyed by persistent and intelligent efforts, and the crops 
substantially saved. They were destructive also in several counties of 
Michigan, such as Lapeer, Manistee, Mason, and Branch. In Antrim, 
however, * the farmers have the inside track,” while the annoyance had 
perceptibly diminished in Monroe, Benzie, Tuscola, Shiawassee, and 
Hillsdale. The beetles were very numerous in Johnson, Martin, Cass, 
Dabois, and Orange Counties, indiana. In Howard, the lady-bug was 
eiliviently destroying them. In Franklin they were less troublesome 
than last year. Paris-green was extensively used in some counties with 
varying success. Great damage was done in Mercer, Ogle, Boone, Lake, 
Winnebago, and Bureau Counties, Ilinois, while in Stephenson, Mont- 
gomery, and Madison they were of small import. La Crosse County, 
Wisconsin, reports an increased number, while in Columbia, Adams, 
Juneau, and Clark they were very troublesome. In Portage they were 
very thick, but were preyed upon by other insects to an increasing ex- 
tent. In Ozaukee they had lost their terrors, being easily destroyed. 
In Brown abundant rains enabled the vines to grow in spite of them. 
Ju Minnesota the devastations were, more severe in Ramsey, Houston, 
Isanti, Meeker, and Wright Counties, while in Renviile they were less 
numerous than formerly. Our correspondent in Rock reports a new 
potato-bug as destructive as the striped bug. He will greatly oblige us 
by sending a specimen. Only three counties in lowa—Tama, Winne- 
shiek, and Muscatine—report the presence of the Colorado beetles ;
