4O INSECTA. 
The other Cicadaria—Mute—have but three distinct joints 
in the antennz, and two smali ocelli. Their legs are usually 
adapted for leaping. Neither of the sexes is provided with 
organs of sound. 
The elytra are frequently coriaceous and opaque, Several 
females envelope their eggs with a white substance resembling 
cotton. 
Some of them—Fulgorellz—have the antennz inserted immedi- 
ately under their eyes, and the front frequently prolonged in the 
form of a snout, the figure of which varies according to the species. 
By this we distinguish the genus 
Fureora, Lin. Oliv. 
Those species in which the front projects, that have two simple 
eyes, and which present no appendage under the. antenne, are the 
Fulgorz, properly so called, of Fabricius. Such is 
F. laternaria, L.; Rees., Insect. II, Locust., xxviii, xxix. 
A very large species, prettily variegated with yellow and 
russet; a large ocellated spot on each wing; snout strongly di- 
lated, vesicular, broad, and rounded anteriorly. Travellers 
assure us that this Insect diffuses a strong light when in the 
dark. 
The south of Europe produces a small species of the same genus. 
It is the 
F. europxa, L.3; Panz., Faun. Insect. Germ., XX, 16. Green, 
with a conical front, and transparent elytra and wings(1). 
Other Cicadarie with a projecting front, but destitute of sim- 
ple eyes, and furnished with two little appendages under each an- . 
tenne representing those organs‘or palpi, form the genus 
relative to the species of this genus, are given. Those, in which the first abdo- 
minal segment presents a cleft above that exposes the tymbal, compose the genus 
Tibicen of my Fam. Nat. du Régn. Anim.; such are the C. hematoda of Olivier, 
the T. picta, hyalina, algira of Fabricius, and his 7. orni, which, in this respect, 
might form another genus.
