174 INSECTA. 
the dead twigs to the medulla, in which she deposits her eggs. As 
the number of the latter is considerable, she makes several holes, 
indicated externally by as many elevations. The young larve, how- 
ever, leave their asylum to penetrate into the earth, where they grow 
and experience their metamorphosis. Their anterior legs are short, 
have very stout thighs armed with teeth, and are adapted for digging. 
The Greeks ate the pupa, which they called Tetitqgometra, and even 
the perfect Insect. Previous to coition they preferred the males, and 
when it had taken place the females were most sought for, as their 
abdomen is then filled with eggs. 
The C. orni, by wounding the tree from which its specific name is 
derived, produces that peculiar honey-like and purgative juice called 
manna. 
C. ornt. L. Rees., Insect. II, Locust. xxv, 1, 2;. xxvi, 3, 5, 
About an inch long; yellowish; pale beneath, the same colour 
mixed with black above; margin of the abdominal segments, 
russet; two rows of blackish points on the elytra, those nearest 
their inner margin the smallest. South of France, Italy, &c. 
C. plebeia, L.; Tettigonia fraxini, Fab.; Rees., Ib. XXV, 4, 
6, 7,8. The largest species in France; black, with several spots 
on the first segment of the trunk; its posterior margin, the raised 
and arcuated portions of the scutellum, and several veins of the 
elytra, russet *. 
The other Cicadarie—Mute—have but three distinct joints in the 
antenne, and two small 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—F'u/g orelia—have the antenne inserted immediately 
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 
Fuuicora, Lin. Oliv. 
Those species in which the front projects, that have two simple eyes, 
and which present no appendage under the antennee, are the Fulgore, 
properly so called, of Fabricius. Such is 
F. laternaria, L.; Rees., Insect. I., Locust., xxviii, xxix. A 
very large species, prettily variegated with yellow and russet; 
a large ocellated spot on each wing; snout strongly dilated, vesi- 
cular, broad, and rounded anteriorly. Travellers assure us that 
this Insect diffuses a strong light when in the dark.

tigonia, and Oliv., Encye. Méthod., article Cigale, where all the figures of Stoll, re- 
lative to the species of this genus, are given. Those in which the first abdominal 
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 T. orni, which, in this respect, might form another 
genus.
