ment the results of any experiments they have made with this poison, 
so as to gather together all the facts, that we may know whether it 
should be recommended next year, or condemned. Cotton being the 
great staple of the South, it will be plainly seen that great benefit 
would arise to the South by knowing the true facts in the case, and the 
experience of practical planters, before recommending any remedy that 
wight prove worthless and perhaps injurious. 
PHYLLOXERA VASTATRIX.—The grape-vine-root gall-louse, so de- 
structive to the grape-vine in Hurope, and found in the Western States, 
has been found on the grape-vine roots growing in the gardens of the 
Department of Agriculture at Washington. Mr. J. 1. Planchon, of Mont- 
pellier, France, on his late visit to Washington, made a most thorough 
investigation of the grape-vines, and after examining sixty of the plants 
most thoroughly he found only from four to six of these insects alive 
on the roots. It is also to be observed that this year none of the ieaf- 
gall species, known as the Pemphigus vitifolie, of Fitch, have been 
found on the foliage of the grape-vines at the Department, but the 
vines are very much injured by the small insect erroneously known as 
the grape-leaf thrips, which is a species of frog-hopper, (Hrythroneura,) 
belonging to the order Homoptera, and which “by sucking out the sap 
causes the foliage to assume a withered and spotted ADDEATAB ES and, if 
very numerous, causes the leaves to be shed. 
INSECT INJURIES.—Reports of extensive depredations upon the grow- 
ing crops, by noxious insects, have been received from a large number 
of counties. The Entomologist would here earnestly reiterate the rec- 
commendation of the July report, and request our regular and casual 
correspondents to send to the Department specimens of injuricus in- 
sects that may be operating in their respective localities. It is impossi- 
ble, from the local names and imperfect description by which these are 
frequently designated in our correspondence, to identify the offending 
species. A single specimen would often enable the Entomologist at once 
to recognize the character and habits of the depredator, and to suggest 
effective e means for its extirpation. 
Grasshoppers, (Caloptenus sp.)—These insects have past very destruc- 
tive, especially in the States and Territories west of the Mississippi 
River. It is evident that two species C. spretus and C. femur-rubrum, 
are represented in the accounts received at the Department, but from 
lack of specimens it is impossible to designate, in most cases, the species 
infecting asparticular locality. New Hampshire is the only New Eng- 
land State reporting the presence of grasshoppers. In Carroll County 
the C. femur-rubrum continued to devour the crops until driven away 
by coolnights; in Sullivan these pests destroyed some fields of tobacco ; 
in Grafton they infested some localities. They were also quite destruc- 
tive in Chautauqua and Jefferson Counties, New York. 
Both species have been active in the West and Southwest. Grass- 
hoppers made their appearance in Bossier Parish, Louisiana. They 
were very injurious in Palo Pinto, Parker, and Atascosa Counties, Texas, 
to the grain-crops, and, in some cases, to the fruit. In Montgomery, 
Hancock, and Bradley Counties, Tennessee, they devoured the corn 
and grass crops. They appeared in immense swarms in Jefierson 
County, West Virginia. They appeared in Mahoning County, Ohio, 
and were more numerous than ever in Lorain; in Medina they were 
very destructive in pastures. They were no less numerous in Dubois 
and Newton Counties, Indiana, and threatened the grain and grass. 
crops in Crawford, Lawrence, and Edwards Counties, Illinois. They
