THE TWO-STRIPED SAPERDA.

of the same color on the wing-covers. It is from one inch 
to an inch and a quarter in length. This beetle closely 
resembles the European Saperda carcharias , which inhabits 
the poplar ; and the grubs of our native species, with those 
of the broad-necked Prionus, have almost entirely destroyed 
the Lombardy poplar in this vicinity. They live also in the 
trunks of our American poplars. They are of a yellowish- 
white color, except the upper part of the first segment, which 
is dark buff. When fully grown they measure nearly two 
inches in length. The body is very thick, rather larger 
before than behind, and consists of twelve segments separated 
from each other by deep transverse furrows. The first 
segment is broad, and slopes obliquely downwards to the 
head ; the second is very narrow ; on the upper and under 
sides of each of the following segments, from the third 
to the tenth inclusive, there is a transverse oval space, 
rendered rough like a rasp by minute projections. These 
rasps serve instead of legs, which are entirely wanting. The 
beetles may be found on the trunks and branches of the 
various kinds of poplars, in August and September ; they 
fly by night, and sometimes enter the open windows of 
houses in the evening. 
The borers of the apple-tree have become notorious, through- 
out the New England and Middle States, for their extensive 
ravages. They are the larvae of a beetle called Saperda 
Uvittata * by Mr. Say, the two-striped, or the brown and 
white striped Saperda (Plate II. Fig. 1(5) ; the upper side of 
its body being marked with two longitudinal white stripes 
between three of a light-brown color, while the face, the an- 
tennae, the under side of the body, and the legs are white. 
This beetle varies in length from a little more than one 
half to three quarters of an inch. It comes forth from the 
trunks of the trees, in its perfected state, early in June, 
making its escape in the night, during which time only it 
uses its ample wings in going from tree to tree in search
