Wholly pale greenish white ; wings transparent and sometimes with a pale yellowish-brown patch on top of the head. Antenna- with two elevated Mack marks on the underside, the one on the first joint hooked at the base, with the hook turned inward and the mark on the second joint oblong. Average length from head to tip of wing covers, 14 mm. ; body, 10 mm. ; width, This species is not as common as CE. niveus. It inhabits the higher parts of different kinds of forest and fruit trees. The stridulation is very different from CE. niveus. It is a faint, continuous reeeeeee, lasting about five seconds, and terminating abruptly, with an equal interval of rest. Usually sings at night only, but sometimes also late in the afternoon in shady places, and on cloudy days. The insect may be readily separated from niveus by the much narrower wing covers and the different shaped marks on the basal joint of the antennae. Found from August until the colder weather sets in.

Vellowish green, with three more or less distinct black, Longitudinal stripes on the head ami thorax, which are sometimes entirely black. The legs arc yellowish with a blackish tinge, or entirely black. Underside of body black ; upperside yellowish green. Antenna- black 0| with four black marks on the first two joints. The inner- (Sff most mark on the first joint about twice the length of the outer, and nearly always confluent at the upper ends. On the second joints the marks arc more equal. In mam- individuals the antennae are entirely black ; then the marks are not discernible. Hind wings extending mine or less beyond the wing covers.
