proximated or separated by an interval about equal to that which is 
between each of them and the neighbouring eye. eid 
Next come those in which the body is more or less oblong, with 
‘out being filiform or linear. 
CoreEvs, Fab. 
Where the body is partly oval, the last joint of the antennz ovoid 
or fusiform, frequently thicker than the preceding one, and usually 
shorter, and of equal length at most, in the others. 
They could be separated into several sections, which might even 
be considered; as subgenera, according to the relative proportions , 
and forms of the joints of their antenne(1). : 
C. marginatus; Cimex marginatus, L.; Wolf. Cimic., I, iii, 
20. Length six lines, and of a cinnamon-red; second and third 
joint of the antennz russet, the two others blackish; the two 
first longest of all; a small tooth at the internal base of the first; 
posterior sides of the thorax raised and rounded; abdomen di- 
lated and turned up on the sides, with the middle of its superior 
surface red. On plants; it diffuses a strong odour yack resem- 
bles that of an apple. 
The antenne of the other Geocorise of the same subdivision ter- 
minate by an elongated, cylindrical, or filiform joint.. They consti- 
tute a great portion of the genus Lyczxus of Fabricius, and comprise» 
besides that which he calls Atypus. The posterior legs of the males | 
are most frequently remarkable for the thickness of the thighs, and 
in a great number for the form of their tibiz, which are sometimes 
compressed and have the edges dilated, as if membranous and wing- 
ed, or foliaceous, and sometimes curved. Most of them are foreign 
to Europe. 
To these Lygzi must be pethived those species in which the sim- 
ple eyes are separated from each other by an interval about equal to 
that which exists between each eye and its neighbour, and in which 
(1) Gonocznvs. The last joint of the antenne shorter than the preceding 
one, and ovoid or oval; the latter and the second compressed, angular or dilated; 
the first, or at least the second, est of all. The C. sulcicornis, insidiator, an- 
tennator, of Fabricius. rf 
Synomastss. The last joint of the antennz shorter than the preceding | one, 
and bordering on an oval; the latter, filiform and simple. The C. marginatus, 
scapha, spiniger, paradoxus, quadratus, Fab., and his Lygezus sanctus. 
Corrvs. The last joint of the antenne differing but little in length from the 
preceding one, and almost fusiform; the latter not compressed. The C. dentator, 
hirticornis, clavicornis, acrydioides, cupitatus, Fab. |
