Fore-wings well developed (Hebrus pusillus), or vestigial or absent (usually, in H. ruficeps); in the resting insect lying more or less flat over the abdomen; of macropters, differentiated into a basally thickened and a distally membranous region. Hind coxae mobile; rotatory. Tarsi 2 segmented (the basal segment very small). Claws all apical. Pulvilli absent. The abdomen covered ventrally with dense, silvery pubescence.
