HEMIPTERA. 163 
Certain Geocorise of the same division, with a narrovv and elon- 
gated body, projecting eyes, the ocelli approximated, and the thorax 
merely a little narrower before than behind, and almost trapezoidal, 
form the subgenus 
Atypvus, Fab. *. 
Now come Geocorisz with a very narrow, long, filiform, or linear 
body. The antennz and legs are also proportionally smaller. 
Lerrocorisa, Lat. 
Where the antennz are straight +. 
Neives, Lat.—Berytus, Fab. 
Where those organs are geniculate t. 
We now pass to Geocorisze in which the antennz, also filiform or 
thicker at the extremity and quadriarticulated, are inserted lower than 
the preceding ones, either on an imaginary line, drawn from the eyes 
to the origin of the labrum, or beneath it. The ocelli are approxi- 
mated to the eyes, and the membranous appendages of the elytra fre- 
quently present but four or five nervures. 
Here the head is not narrowed posteriorly in the manner of a neck. 
Lyczus, Fab. 
Where the head is narrower than the thorax, and where the latter 
is narrowed anteriorly and is trapezoidal. 
L. equestris; Cimex equestris, L.; Wolf, Cimic., I, ili, 24. 
Length five lines; red, with black spots; membranous portion of 
the elytra brown, spotted with white. 
L. apterus ; Cimex apterus, L.; Stoll, Cimic., II, xv, 103. 
Length four lines; apterous; red; the head, a spot on the middle 
of the thorax and large dot on each elytron, black; extremity of 
the elytra truncated or without a membranous appendage. Very 
common in our gardens. It is sometimes, though very rarely, 
found with wings. 
Those species in which the anterior thighs are inflated, form the 
genus Pacuymera of MM. Lepeletier and Serville, a name already 
employed, and which must be changed §. 
Saupa, Fab. 
Where the head, taken in its greatest breadth, is as wide as the 
thorax or wider, and has its posterior angles dilated, with large eyes, 
and where the thorax is always of equal width, and square |]. 
There, the head is ovoid and narrowed posteriorly in the manner 
of a neck.
