land, and was briefly reported by Prof. W. G. Johnson (Bul. 57, Md. 
Agric. Exp. Station, p. 5). During that year serious damage was 
done to the potato crop in Kansas, with the result that the insect 
was given special study by Messrs. Faville and Parrott in a 12-page 
leaflet (Bul. 82, Kansas State Agric. College Exp. Station). This 
isa very full account and includes 15 illustrations. A short summary 
of this article was published as Press Bulletin 19 in December, 1808, 
and republished in Bulletin 86 (pp. 35-37). Injury was also inflicted 
the same year in Pennsylvania, complaint having been made at Pawling, 
in the vicinity of which place infestation was stated to have been 
evidently quite general (2d An. Rept. Pa. Dept. Agr. for 1896 [1897], 
pp. 361-363). 
In 1897 the potato stalk weevil was reported as doing much injury 
in Baltimore County, Md. (Bul. 9, n. s., p. 81). 
In the Rural New Yorker for August 27, 1898, correspondence is 
published, with answer by Mr. Slingerland, concerning the occur- 
rence of this species in potato vines at Pittsville, Pa., that year. 
Owing to its extensive depredations in the potato fields in northeast- 
ern Maryland, especially in Harford County, during 1898, an account 
by Prof. E. Dwight Sanderson was published in the National Stock- 
man and Farmer for December 8, 1898. 
During 1899 no reports of injury came to the writer’s attention. 
Moreover, the species was rare wherever sought for in the vicinity of 
the Distrit of Columbia. 
In the Rural New Yorker for August 11, 1900 (p. 544), a short note 
is published on the occurrence of this species at South Holland, IIl., 
where it had injured nearly every stem of potatoes, destroying about 
half the crop. An answer by Mr. Slingerland accompanied this note. 
In Dr. Fletcher’s report as entomologist and botanist for the 
experimental farms of Canada (p. 234, 1902), he makes mention of 
the occurrence of this species for the first time as a Canadian insect. 
The report is on the authority of Professor Lochhead, and is in brief 
that many vines were completely destroyed by the potato stalk weevil, 
present in all stages in September, at Pelee Island. It was stated 
that the island exported 30,000 bushels of potatoes the previous year, 
but in 1901 it would have no more than enough for its own consump- 
tion and none to spare. This report is followed by a short general 
account of the insect, with remedies. 
NATURE OF INJURY; FOOD PLANTS. 
Frequently, more often perhaps than not, injury by this potato 
pest is attributed to drought or blight. It is more conspicuous in sea- 
sons of prolonged drought and most severe on early varieties of potato. 
The undermining of the stalks of potato by the larve causes them to 
wilt, and the wilting and the dying of the leaves is the first and only
