notum, and scutellum finely tuberculate, with short, recumbent, spinelike hairs; corium and clavus finely punctate, with similar hairs; dorsal surface of abdomen ferruginous, hairless, rather coarsely punctate; ventral surface of body more finely punctate, with dark stippling and fine, pale, recumbent, spinelike hairs; connexivum clothed with very short, fine hairs, a narrow pale posterior band in each segment; abdominal sternites II–IV mesially sulcate, shallowly so in ♀. Nymphs The late instar nymphs are similar in general appearance to adults except in wing development. The following description applies to both sexes of such a nymph (probably fifth instar): Length, 7·5 mm.; colour brown, with pale apex of antenna very clearly marked; all tibiae with pale middle region, dark at base and apex; mottling and banding of femora, tubercles and spinous hairs on head, pronotum, and scutellum, processes of antenniferons tubercles, and protuberances behind eyes, as in adult; anterior angles of pronotum less strongly produced than in adult; pale connexival areas less pronounced; wingpads, ventral surface of head and thorax, femora, and basal segment of antennae impunctate but with fine tubercles and short spinous hairs as on pronotum; dorsal surface of abdomen, including connexivum, and ventral surface of abdomen impunctate, with short, fine, pale, recumbent hairs; ventral surface of connexivum very finely tuberculate; pronotum with all margins nearly straight, posterior angles rounded and scarcely raised, posterior margin not declivous; a narrow, very slightly raised, pale median line on head, pronotum, and scutellum; wing-pads extending to posterior margin of second visible abdominal segment; dorsal lips of odoriferous apertures prominently raised, very dark, transversely wrinkled. An earlier instar (probably second) shows the following characteristics: Length, 3·5 mm.; both surfaces of body a very pale straw-yellow ground-colour with distinctly reddish-brown mottling; antennae dark brown, except for the reddish-brown base of the third segment and the pale apical two-thirds of the fourth; darker brown markings on tylus, on each side of median line of vertex, and submarginally on thoracic tergites; epicranial suture well marked as a fine red line; connexivum with in each segment a dark brown patch and an anterior and a posterior pale area; lips of odoriferous apertures as described for later instar, but the members of each pair forming a completely united raised dark area; colour pattern of femora and tibiae as for later instar; antenniferous tubercles and anterior pronotal angles not produced; lateral margins of head behind eyes somewhat dilated, but not knob-like as in later stages; pronotum short, with anterior and lateral margins nearly straight, posterior margin convex; first 3 segments of antennae finely tuberculate, with short, spine-like, semirecumbent hairs arising from tubercles, fourth segment more densely clothed with longer hairs; a few small scattered tubercles on head and pronotum; dorsal surface of head, thorax, and abdomen with very short, scattered hairs; punctation completely absent.
