ORTHOPTERA. 
the head whitish, or only faintly tinted with green, and the 
legs and abdomen are pale brownish-green. A little tooth 
projects downwards from the under side of the conical part 
of the head, which extends between the antennae, and imme- 
diately before this little tooth is a black line bent backwards 
on each side like the letter U. The hindmost thighs have 
five or six exceedingly minute spines on the inner ridge of 
the under side. The shrilling organ of the male on the left 
wing-cover is green and opaque, but that on the right has 
a space in the middle that is transparent like glass. The 
piercer of the female is above an inch long, very slightly 
bent near the body, and is perfectly straight from thence to 
the tip, which ends in a point. The color of this grasshop- 
per is very apt to change after death to a dirty brown. It 
comes very near to the dissimilis described by M. Serville, 
but appears to be a different species.* 
* In the collection belonging to the Boston Society of Natural History, there is 
an insect which I suppose to be the Conocephalus dissimilis of Serville. It was 
taken in North Carolina by Professor Ilcntz. The conical projection of the head 
is shorter and more obtuse than in the ensiger , the sides of the thorax are brown- 
ish, the hindmost thighs have a double row of black dots on the under side, and 
the spines on this part are more numerous and rather larger. Professor Hentz has 
sent to me from Alabama another species distinct from both of these, about the 
same in length, but considerably broader. The conical part of the head between 
the eyes is broader, flattened above, and, as well as the thorax, rough like shagreen. 
There is a projecting tubercle beneath, but the curved black line is wanting, and 
the tip of the cone has a minute point abruptly bent downwards, and forming a 
hook. The sides of the thorax are bent down suddenly so as to make an angular 
ridge on each side of the middle. The wing-covers are dotted with black around 
their edges, and have also an irregular row of larger and more distinct spots along
