in the canyons there are large cottonwood and hackberry trees and 

 grape vhies. Along the rough, rugged sides of the canyon are cedars 

 and small bushes, that are called here skunk bushes, and soap-weeds, 

 or bear grass. It was on these small bushes and bear grass that I 

 captured the cicadas. It was about 2.30 or 3 P. M. I located them 

 by their singing, which was very shrill." 



Tibicen species? 



Black Canyon near Bumble Bee, Arizona, July 30, 1917, female 

 (H. H. K.). I have no male with which to compare this specimen, 

 and it is therefore doubtfully placed, but it resembles Tibicen inaiiditus, 

 though larger. 



Tibicen duryi new species. 



Type male, Jemez Springs, New Mexico, 7,000 ft., June 27, 191 7 

 (John Woodgate). Davis collection. 



Allotype female, Box Canyon, Grant County, June, 1912 (Charles 

 Dury). Davis collection. 



A black and reddish species much resembling an Okanagana in coloring, 

 especially when the wings are closed. The head at the eyes not much 

 broader than the front margin of' the pronotum. 



Head above black with the following marks deep orange in color: a 

 spot on front, a somewhat triangularly shaped one just behind this, one above 

 each antenna, and one irregular spot each side of the ocelli at the back of 

 the head extending to b\ck of the eyes. > Pronotum black margined with 

 orange, and slightly broader so on the posterior margin than on the anterior 

 and sides. The tops of the raised portions occupying the central part of the 

 pronotum are deep orange-colored and darker than the margins. Mesonotum 

 black with a pruinose spot each side near the anterior margin (sometimes 

 nearly obliterated), and a pruinose stripe each side near the base of the 

 wings. The hind margin, the elevated portion of the X, two spots at the 

 extremities of the X, and four spots (two inner curved) beyond the de- 

 pression, orange. Tergum black with two' pruinose spots at the base, one 

 large one each side below the tympanum on the third segment, and also more 

 or less conspicuously pruinose on the eighth segment. The posterior margins 

 of all of the segments, except the first and second, narrowly lined with red, 

 which is conspicuously broadened on the eighth segment of the female. The 

 female from Fort Grant, Arizona, has a blacker dorsum, but the hind margin 

 of the eighth segment is conspicuously red. Fore wing with the costal 

 margin straw-colored to the end of the wing ; subcostal vein black ; first and 

 second cross veins infuscated. The basal cell of each fore wing with about 

 the outer half conspicuously blackened ; more clear at base. The wings are 

 red at base, including the flaps of both the fore and hind pair. There are
