THE OBLONG LEAF-WING.

one eighth of an inch in length. They resemble tiny oval 
bivalve shells in shape. The insect lays them in two con- 
tiguous rows along the surface of a twig, the bark of which is 
previously shaved off or made rough with her piercer. Each 
row consists of eight or nine eggs, placed somewhat obliquely, 
and overlapping each other a little, and they are fastened to 
the twig with a gummy substance. In hatching, the egg splits 
open at one end, and the young insect creeps through the cleft. 
I am indebted to Miss Morris for specimens of these eggs. 
We have another broad-winged green grasshopper, differ- 
ing from the katy-did, in having the wing-covers narrower, 
flat and not concave, and shorter than the wings, the thorax 
smooth, flat above, and abruptly bent downwards at a right 
angle on each side, and the breast without any projecting 
spines in the middle. The piercer has the same form as that 
of the katy-did. The musical organ of the left wing-cover, 
which is the uppermost, is not transparent, but is green 
and opaque, and is traversed by a strong curved vein ; that 
of the right wing-cover is semi-transparent in the middle. 
This insect is the Phylloptera oMongifolia,* (Fig. 75,) or oh-

long leaf-winged grasshopper. Its body measures about an 
inch in length, and from the head to the tips of the wings, 
from an inch and three quarters to three inches. It is found 
in its perfect state during the months of September and 
October, upon trees, and, when it flies, makes a whizzing 
noise somewhat like that of a weaver’s shuttle. The notes
