HEMIPTERA. 175 
The south of Europe produces a small species of the same genus. 
It is the 
F. europe, L.; Panz., Faun. Insect, Germ., XX, 16. Green, 
with a conical front, and transparent elytra and wings *. 
Other Cicadarize with a projecting front, but destitute of simple 
eyes, and furnished with two little appendages under each antenne 
representing those organs or palpi, form the genus 
Oriocerus, A7rb., 
Or the Cobax of Germar, which hitherto seems to be peculiar to 
the western continent f. 
Those, in which the head presents no remarkable projection, com- 
pose various genera of Fabricius, to which must be added some others 
established since the time of that naturalist. 
Sometimes the antenne are shorter than the head, and inserted out 
of the eyes, a character which is also common to the two preceding 
genera. 
Here we distinguish two very apparent ocelli. 
Lystra, Fab. 
These Insects at the first glance resemble little Cicade, properly 
so called. The body and elytra are elongated. ‘The second joint of 
the antennz is almost globular and granose, as in the Fulgoree }. 
Cixtus, Lat. 
The Cyxii resemble the Lystra, but the second joint of the an- 
tenne is cylindrical and smooth §. 
Under the generic appellation of 
TETTIGOMETRA, Lat., 
I ‘have separated certain Insects analogous to the preceding spe- 
cies, but in which the antenne are lodged between the posterior and 
lateral angles of the head, and those of the anterior extremity of the 
thorax. ‘The eyes are not prominent ||. 
There, we observe no ocilli. 
Those species that have large elytra, and in which the prothorax is 
sensibly shorter in its middle than the mesothorax, compose the sub- 
genus 
PecitoprEra, Lat. Germ.—F ata, Fab. 4. 
Those, in which it is at least as long as the mesothorax, and where

The Celidie of this author—Ib., p. 75—seem to approach the Tettigometre. 
They have the same port, and, according to him, their anatenne are inserted under 
the eyes.
