Hesus, Stal, Stett. ent. Zeit. 1862, p. 437; Enum. Hemipt. iii. pp. 189, 141. 
A Tropical-American genus including three or four variable species. The Central- 
American representatives may be separated thus :— 
The inner pronotal callosities narrowly separated anteriorly, the intervening 
space depressed ; apical process of the head feebly bilobed in front . . cordatus, F. 
The inner pronotal callosities less approximate, the intervening space tuber- 
culate, the tubercles sometimes fused and forming two longitudinal, 
anteriorly diverging rugz ; apical process of the head distinctly bilobed

We have obtained fourteen specimens of this species from within our limits, all but 
one of them being from Chiriqui. 
The male of the insect described by Stal as H. cordatus (Fabr.), communicated by 
Dr. Aurivillius, differs from the Chiriqui examples of the same sex in having the 
abdomen slightly constricted at the sides beyond the middle, with the apical angles of 
the fourth segment a little less prominent ; but this peculiarity is more apparent than 
real. ‘The females agree precisely with the types of H. annuliger, Stal, and H. cincti- 
cornis (Walk.). Of the latter there are five specimens (¢ 2) in the British Museum. 
H. cordatus chiefly differs from H. flaviventris in having the two inner callosities on 
the pronotum more approximate, the narrow groove between them being without 
conspicuous tubercles or ruge; it also has the basal joint of the antenne usually a 
little more elongate and the apical process of the head more feebly bilobed. 
The insect is also constantly paler in colour. The antenne incline to ferruginous, 
the basal joint included, the apex of the third joint and the base of the fourth being
