174 INSECTA. 



the dead twigs to the medulla, in which slie deposits her eggs. As 

 the number of the latter is considerable, she makes several holes, 

 indicated externally by as many elevations. The young larvte, 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 ;ite the ])upee, which they calliict Tetligomeh-a, 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 X7. orni, by wounding the tree from which its specific name is 

 derived, produces that peculiar honey-like and jjurgative juice called 

 manna. 



C. orni. L. Rces., 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. pTettigonia fraxini. Fab. ; Ra;s., lb. XXV, 4, 

 6, 7i 8. The largest species in France ; black, with several spots 

 on the first segment of the tnmk ; its posterior margin, the raised 

 and arcuated portions of the scutellum, and several veins of the 

 elytra, russet *. 

 The other CicadariEe — 3TutfE — have but three distinct joints in the 

 antennae, 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 Avith a Avhitc substance resembling cotton. 



Some of them — Fulgorellce — have the antennae 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 



f ^ FuLGORA, Lin. Oliv. 



Those species in which the front projects, that have tAvo simple eyes, 

 and which present no appendage under the antennae, are the Fulgorce, 

 properly so called, of Fabricius. Such is 



V '^ F. laternaria,li.; Ro?s., Insect. II., Locust., xxviii, xxix. A 

 very large species, prettily variegated with yellow and russet ; 

 a large ocellated spot on each Aving ; snout strongly dilated, vesi- 

 cular, broad, and rounded anteriorly. Travellers assure us that 

 this Insect diffuses a strong light Avhon in the dark.
