near the humeral angles. Mesonotum with two short obconical black spots at 

 the fore margin, on either side of which there is a much dissected dark band, 

 broadest anteriorly and extending backward to the extremities of the elevated 

 X ; there is also a dark stripe extending along each side from the x to the 

 base of the fore wings. There is an irregular cross-shaped spot between the 

 X and the two central obconical spots, and the two depressed black points, 

 common to many species, and near the anterior extremities of the x are also 

 present. The x and lighter lines on the mesonotum are yellowish in the type, 

 but the X is greener in the paratypes. The tergum is testaceous ; the tympanal 

 areas lighter, each darkly clouded near its center, and the segments are lighter 

 in color along their posterior margins. The dorsal surface is more or less 

 covered with a short, silken, light-colored pubescence. The fore wings have 

 the costal margins greenish yellow for about half of their length, beyond 

 which they are blackened ; the subcostal veins are dark brown. The first and 

 second cross veins of the fore wings are clouded, and the flaps at the base of 

 both fore and hind wings are whitish or grayish white. Beneath lighter col- 

 ored and pruinose, blackened about the eyes, the legs yellowish, streaked and 

 spotted with testaceous. The abdomen nearly uniformly colored except the 

 darker spot on the last ventral segment and a linear one on the valve; seg- 

 ments slightly darkened along the base. Opercula yellowish, a little less than 

 half the length of the abdomen and rounded at the extremities, the inner edges 

 almost touching. Uncus when viewed in profile with the inner edge not

deeply notched, as in some species, but more rounded with the extremities 

 bent inward, and when viewed from behind the hard raised portion resembles 

 in shape a widely arched wish-bone. In Cicada sordidata Uhler the uncus, 

 when viewed in profile, has the claw-like extremities freer and bent inward to 

 a greater extent, and when viewed from behind the wish-bone arch is not 

 as wide.
