The Central-American specimens agree with the Bogota insect mentioned by Stal 
(now before me), all of them having the anterior lobe of the pronotum partly flavous. 
The colour of the pronotum is variable, the transverse black fascia on the posterior 
lobe being sometimes obliterated or divided into two spots. In the South-American 
examples the anterior lobe is sometimes black, as described by Fabricius and Signoret *. 
The males have the last genital segment deeply emarginate on each side of the 
produced median lobe, the latter being rounded at the apex; the claspers are long 
and somewhat sinuous, and strongly hooked at the tip, the latter being blunt. The 
females, like the males, have the venter very sparsely pilose.

An American genus ranging from Canada to the Argentine Republic, including a 
large number of species, the majority of which are tropical. Eighteen are here recorded 
from within our limits, four of them being described as new; A. ochropterus, Stal, and 
A. rubrocinctus, H.-S., ave, however, included with some doubt. Many of the species 
are so variable in colour that they can only be separated by the form of the terminal 
genital segment of the males, or by the structure of the first genital (terminal dorsal) 
segment of the females. In the males the apex of the last genital (ventral) segment, 
which in several species is produced into a short process, is either armed with two long 
spines—usually curved upwards and obliquely divergent (A. hirtipes, A. subpiceus, &c.), 
but sometimes horizontal and laterally extended (A. flaviventris, &c.),—or has a single 
long unarmed truncated process (A. /anipes); the long lateral hooks or claspers, which 
* In the Stockholm Museum there is an Agriocoris, from the Amazons, which differs from our insect in 
having the base of the pronotum produced into a prominent rounded lobe on each side of the median 
emargination (a character not indicated in Signoret’s or Stoll’s figures): this form is noticed by Stal in his 
remarks on A. curvipes, and the name he suggests, A. fasciata, can be used for it.
