Tue CoLoraDo Poraro BEETLE IN Naes, Miıcureax. — While 
in Niles, Michigan, this winter, I took somewhat special: pains to 
gain information in regard to the Colorado Potato Beetle, as it had 
been observed on one farm in that town. On the farm of James 
Hudson, of whom I made my inquiries, not a bug of this sort was 
seen before or during the year 1868; but a very few were seen on 
a farm about half a mile to the west. In the summer of 1869, 
this beetle appeared on Mr. Hudson’s potatoes, when they were 
about a foot ‘high; when he first saw them only two or three 
were on a hill, but they increased all through the season. 
In April, of 1870, Mr. Hudson in plowing his fields, ploughed 
up the full grown beetles, and they walked about, being very lively. 
He planted Early Rose potatoes about April first, and as soon as 
they were fairly up these beetles commenced their attacks upon 
them. He began to kill them by squeezing them between two 
paddles, going over the ground daily, but apparently without check- 
ing them. He then mixed Paris Green with ashes and sprinkled 
the mixture on a dozen rows, the vines at this time being à foot 
high, and from these rows he secured a fair crop of potatoes. 
Where the mixture was not sprinkled, the bugs ate all the leaves, 
and in many cases they ate the stalks to a considerable extent. 
They now began on a new field hitherto untouched, appearing m 
such numbers as almost literally to cover both the leaves and the 
stalks. They were so numerous that in less than an hour one man 
gathered about twenty quarts of them! They readily drop from 
the vines and then feign death. The beetles swept right through ‘ 
this field, going at the rate of about ten or twenty rods mn? — 
week. Their yellowish eggs were always abundant on the under 
side of the potato leaves; but they also laid their eggs °” 
weeds, spires of grass, and even on dry sticks! While the havo, —— 
above described, was going on, no other species of insects attacked 
the potatoes. At this time the Colorado bugs were abundan
