Antennae longer than the head, readily visible from above; 4 segmented; non-aristate; with segments 3 + 4 less than twice as long as 1 + 2. Ocelli present. Metathorax with a scent-gland opening, comprising a funnel surrounded by a dull patch of elaborately sculptured cuticle, visible laterally on either side. Fore-wings well developed (mostly), or vestigial or absent; when macropterous, with a costal fracture and cuneus; of macropters, with a clavus. Tarsi 3 segmented; two-clawed. Claws all apical.
