/p<?7] Some Grasshoppers of North Carolina. 73 
leaves among- which they live, but in the autumn when the 
leaves fall and the twig's become gray or brown, these insects, 
being then near maturity, turn gray in color. These remark- 
able resemblances, combined with their deliberate movements, 
render them quite difficult to detect, unless they force them- 
selves accidentally upon one’s notice. 
Eritettix navicula. This is one of the true grasshoppers, 
which so far as has been observed inhabits rather low, grassy 
grounds. It is an exception in that it is'the only species 
which has the antennael enlarged into a knob or club, at the 
tip. 
Trimerotrofis saxitalis. This very remarkable grasshopper 
is an inhabitant of the exposed, lichen-covered surface of the 
rocks on some of our mountains. In his trip through the 
Southeastern States Prof. Morse failed to take it in this State, 
but recorded its presence on the summit of Stone Mountain, 
in Northern Georgia. In September last (1906) Mr. Woglum 
and myself took it quite commonly in favorable spots on the 
summits of Satula and Whiteside Mountains, near Highlands, 
Macon County. The species bears a remarkable resemblance 
to the lichen-covered rocks on which it is found, and when 
flushed will invariably settle again on the rock, it being only 
in most exceptional cases that they could be persuaded or 
forced to alight in grass or herbage. When cornered they 
would quickly fly back within a foot or two of the collector 
to , again reach the rock, although the species is quite shy 
when once disturbed. 
Lefty sma ma?‘ginicollis. This species is found in grassy 
places where it clings to the upright stalks or blades, so 
closely applying its body to the grass as to render detection 
difficult, both the shape and color of the insect being protect- 
ive. One remarkable feature of this insect is the fact that 
the front of the head (or face) slopes away under the body in 
such degree that the mouth is situated almost between the 
front legs.
