28 INSECTA. 
straight, sheathed at base or throughout its length; where the eyes 
are of an ordinary size, and where the head at its junction with the 
thorax exhibits no appearance of an abrupt neck or strangulation. 
Their body is usually altogether, or in part, membranous, and 
most commonly much flattened(1). They compose the greater part 
of the primitive genus 
Acantuia, Fab. 
Which that author afterwards divided as follows: 
Syrris, Fab.—Macrocephalus, Swed. Lat—Phymata, Lat. 
Where the anterior legs resemble the monodactyle claw of the 
Crustacea, and are used by these Insects to seize their prey(2). 
Tincis, Fab. 
Where the body is very flat, and the termination of the antennz 
globuliform; the third joint is much longer than the others. 
Most of the species live on plants, piercing their leaves or flowers, 
and sometimes producing false gall-nuts. The leaves of Pear trees 
are frequently riddled by one of this genus, the 7. pyri, Fab.(3) 
Arapus, Fab. 
Similar to Tingis, in the form’ of the body, ore with cylindrical 
antenne, of which the second joint is almost as large as the third, 
or is even longer. 
They are found under the bark of trees, in the cracks of old wood, 
&c.(4) 
Cimex, Lat.—Acanthia, Fab. 
In Cimex proper the body is very flat, but the antenne terminate 
abruptly in the form of a seta. We know but too well the 
(1) These Insects, in our Fam. Nat. du Rég. Anim., form the second tribe of 
the Geocorise, that which I have there designated by the term membraneuse. 
(2) Fab., Syst. Ryngot. In Microcephalus—S. manicata, Fab.—the antenne, 
terminated by a very large joint, are not lodged in inferior cavities of the margin 
of the thorax; the scutellum is distinct, and covers alarge part of the abdomen. 
In Phymata, the antenne are received into peculiar cavities under the lateral 
edges of the thorax, which is prolonged into a scutellum, and only covers a por- 
tion of the abdomen. See Lat.; Gen. Crust. et Insect., ILI, p. 137, 138.
