Where the third joint of the antenne is conical and terminated by 
an inarticulated seta.

xxlll. Brown, with two white spots on the elytra near their ex- 
terior margin. Its larva lives on leaves in a spumous and 
white fluid, called Ecume printaniére, Crachat de Grenouille *, 
In the other Cicadariz that complete this family, and which in the 
early works of Fabricius composed his genus Cicada, the prothorax 
is not prolonged posteriorly (or hardly not) and terminates at the 
height of the origin of the elytra in a straight line, or in one that is 
nearly so, the length of which is almost equal to the width of the 
body. ‘The scutellum, measured at base, occupies a large portion of 
this breadth. 
Two very prominent eyes, a head projecting somewhat beyond 
those organs, but depressed anteriorly, and forming a sort of arch at 
the summit of the elevated portion of the face, situated directly be- 
neath, two superior posterior ocelli, and, finally, by an exception in 
this division, legs destitute of spines or teeth, distinguish the

To this subgenus belongs the species which he calls the 
E. obtecta; Cercopis erice, Arh., Faun. Insect., IIT, 24. It 
is about one line in length; reddish and spotted with white; the 
elytra are marked with two oblique bands of the same colour, 
and numerous and projecting nervures. The head is broad and 
as if truncated anteriorly +. 
Evurenix, Germ. 
Where the head is much flattened and forms an elongated triangle, 
with the ocelli situated before the ordinary eyes on its edges, which 
are prolonged over those organs and intersect them longitudinally 
throughout the greater portion of their extent ft. 
Penrumia, Germ. 
Where the antenne& are inserted in a Jarge fossula, which narrows, 
more than is usual, the space comprised between the eyes. 
The head, which viewed from above appears semicircular and gra- 
dually inclined anteriorly, is rounded, and its edges project above this 
* This species, and some other Cercopes of Fabricius form the genus Aphrophora 
of M. Germar. The posterior margin of the head is concave; and their simple eyes 
are more distant from each other than in Cercopis proper. See his Magas. der En-
