By this we distinguish the genus FuLGORA, Lin. Oliv.

Trav.ellers assure us that this Insect diffuses a strong light when lD the dark. The south of Europe produces a small species of the same genus. It is the F. europrea, L.; Panz., Faun. Insect.

Other Cicadarioe with a projecting front, but destitute of sim· pie eyes, and furnished with two little appendages under each an· tenn<e 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 tymba1, compose the ~e~us Tibicen of my Fam. Nat. du Regn. Anim.; such are the C. lUJJmatoda of Olivter, the T. picta, hyalina, algira of Fabricius, and his T. orni, \yhich, in this respect, might form another genus.

Or the Cobax of Germar, which hitherto seems to be peculiar to the western continent(!). . Th~se, in which the head presents no remarkable projection, compose various genera of Fabricius, to which must be added some others established since the time of that naturalist. Sometimes the antenn:;e 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 Cicadce, properly so called. The body and clytra are elongated. The second joint of the antenn:;e is almost 'globular and granose, as in the Fulgorce(2). Cxxxus, Lat. The Cyxii resemble the Lystrce, but the second joint of the antennce is cylindrical and smooth(3). Under the generic appellation of TETTIGOMETRA, Lat. • I have separated certain Insects analogous , to the preceding species, but in which the an ten nee 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( 4). There, we observe no ocelli. Those species that have large elytra, and in which the prothorax (1) Lin. Trans., XII, 0.
