peach, plum, etc. The body is a little more than one-third of an 
inch long, slender and tapering a little towards each extremity. 
Its color is dull yellowish when fresh, arising from its being 
covered with a grayish-yellow down or bloom and its long sprawl- 
‘ing legs are of a dull pale-reddish hue, with the joints of the 
feet tipped with black and armed with very long claws. The 
down on the body of the bettle is easily rubbed off, producing 
quite a change in its appearance, the head, thorax and under side 
of its body becoming of a shining black. 
“These beetles sometimes appear in swarms about the time of 
the blossoming of the rose, which in the northern United States 
and Canada is usually during the second week in June; they 
remain about a month, at the end of which period the males 
become exhausted, drop to the ground and perish, while the 
females burrow under the surface, deposit their eggs, then reap- 
pear above ground and shortly afterwards die also. 
“Each female lays about thirty eggs, which are buried in the 
earth to the depth of from one to four inches; the eggs are 
about one-thirtieth of an inch in diameter, whitish and nearly 
globular. In about three weeks they hatch, and the young 
larvee at once begin to feed on such tender roots as are within 
their reach. They attain full growth in the autumn, when they 
are about three-quarters of an inch long and about an eighth of 
am inch in diameter, of a yellowish-white color with a tinge of 
blue toward the hinder extremity, which is thick, obtuse, and 
rounded; the head is pale red and horny, and there a few short 
hairs scattered over the surface of the body. In October the 
larva descends below the reach of frost, and passes the winter in 
a torpid state; in the spring it approaches the surface and forms 
. for itself a little oval cell of earth within, which it is transformed 
to a pupa during the month of May. 
“In form the pupa bears some resemblance to the perfect insect, 
and is of a yellowish-white color, its whole body being inclosed 
in a thin film that wraps each part separately. In June this 
filmy skin is rent, when the enclosed beetle withdraws its body 
and limbs, bursts open its earthen cell, and forces its way to the 
surface of the ground, thus completing its various stages within
