In this genus the lateral lobes of the head are longer than the central, the lateral 
margins of the pronotum are denticulated or crenulated, and the lateral angles distinctiy 
and acutely produced, the body is always more or less flattened or depressed, and the 
abdomen beneath is longitudinally and centrally sulcated. This last character, however, 
is a somewhat uncertain one ; for since Dallas on this structural character placed the 
genus in his family Halydide, and Stal, who correctly placed it immediately preceding the 
genus Lowa, yet still relied upon the sulcated abdomen as a strong differential character 
in his ‘ Conspectus Generum,’ species have been discovered in which this ventral furrow 
is very obscure and confined to the base of the abdomen only, thus approaching closely 
the following genus. The apexes of the femora are unarmed. Chlorocoris is a truly 
Neotropical genus; and it apparently has its headquarters in Central America. 
A. Head long, triangular ; lateral lobes much produced and subacute.

This species varies in sometimes having the lateral denticulated margins of the pro- 
notum and basal margins of the corium sanguineous: this is particularly observable in 
two Nicaraguan and one Colombian specimen, the only individuals from these regions 
which I have as yet seen. 
The specimen figured is from Chontales.
