ISCHNOCORIS, Feb. 
Subelongate, head short, eyes large, almost touching the 
anterior margin of the pronotum, the distance between 
them hardly so wide as twice the width of the eye, an- 
tenniferous tubercles small, ocelli distinct, rostrum reach- 
ing to just beyond the intermediate cox; pronotum 
slightly widened posteriorly, more so in the developed 
form; elytra with the membrane generally shortened and 
the wings undeveloped, but in the developed form the 
membrane reaches to beyond the apex of the abdomen; 
apical margins of the abdominal segments above simple ; 
anterior femora not toothed or spinose. There are three 
European species of this genus, all closely allied.
