HEMIPTERA. 45 
subgenera of the same division by several characters. The head, 
viewed from above, merely presents a transversal edge; the front 
is abruptly inclined, and the ocelli are situated there between the 
ordinary eyes, and consequently inferiorly. The antennz, very 
small and distant from these latter organs, are inserted beneath an 
ideal line drawn from one to the other. The space immediately 
under the front is flattened and smooth. The tibiz are neither 
ciliated nor dentated(1). 
In the three succeeding subgenera, the vertex is triangular and 
bears the ocelli. The antennz are inserted in an ideal line drawn 
from, one ordinary eye to the other or above it.

Lepra, Fab. 
Where the head is much flattened before the eyes, in the form of 
a transversal clypeus, arcuated, and terminated in the middle of the 
anterior margin by an obtuse angle. All the under part of the head 
is plane or ona level. The sides of the prothorax project in the 
manner of horns rounded at the extremity, or of pinions. The pos- 
terior tibiz are strongly compressed and as if bordered externally 
by adentated membrane. The 
L. aurita; Cicada aurita, L.; Cigale Grand-Diable, Geoff., 
belongs to this subgenus(2).

where the editors, Messrs Lepeletier and Serville, offer some new considerations 
and establish new genera, but with which I was unacquainted until I had terminated 
my work on this family, and consequently had no time to verify, on the Insects 
themselves, the characters which they assign to those sections. I will restrict my- 
self to the following remark. The description of the Hurymele fenestrée exactly 
agrees with a species figured by Donovan, in his splendid work on the Insects of 
New Holland, and consequently the editors of the article in question must have 
been deceived as to the habitat of this Insect, which they say is from Brazil. In 
case this synonyme be correct, the distinctive character of this new genus, the 
absence of simple eyes, would be false, for they exist on the superior part of the 
front, although, at first, they are not easily perceived. This species would 
then re-enter the subgenus Jassus.
