Species: O. Canadensis
Okanagana canadensis, the Canadian cicada, is a species of cicada in the family Cicadidae. It is found in North America.
The genus Okanagana probably contains more species of cicadas than any other in North America, and they are also in many instances quite hard to separate. In, the northeastern part of the continent there appear to be only two species, but in the central and western parts it is far otherwise, and in California they are very numerous.
As a rule the individuals of the same species resemble one another quite closely in color pattern, but occasional variation is seen, espe cially when the species is rather widely distributed.
The original description of the, genus Okanagana was published in the Annals and Magazine of Natural. History, Seventh Series, Vol ume XVI, pp. 23, 190, I905, and is as follows: "Head (including eyes) considerably narrower than base of mesonotum and almost equal to its length (including cruciform elevation) ; front shorter than vertex, its apex more or less emarginiate, vertex centrally sulcate; pronotum about as long as head, its anterior angles in a line with eyes, its posterior angles dilated; abdomen in male longer, in female about as long as space between apex of head and base of cruciform elevation; tympana completely exposed, tympanal coverings entirely absent; face more or less centrally sulcate; rostrum reaching the intermediate coxxe; opercula small, transverse; abdomen beneath with the lateral margins broadly recurved; tegmina and wings hyaline; tegmina with the basial cell about or almost twice as long as broad, apical areas eight; wings with six apical areas.
