June-Sept.. I9I9.] DaVIS : CiCADAS. 197 



peared to cease, and it came from everywhere — from the tops of the 

 trees, from the trembling leaves of the Cottonwood, from the stunted 

 underbrush, from the flowers, the rocks and boulders ... all chanting 

 the same refrain. ... It turned out to be an entirely new species, and 

 now figures in the British Museum as Cicada occidentalis." Dr. 

 Charles J. Gahan has written me under date of May 12, 1919, that 

 this specimen cannot at the moment be located in the British Museum. 

 It would appear from Lord's original narrative that the type locality 

 for this species is in the north-eastern part of the present state of 

 Washington in Colville Valley, where the Boundary Line Commission 

 had its headquarters. 



In the collection of the United States National Museum there is 

 a female occidentalis from Victoria, Vancouver, H. G. Hubbard col- 

 lector, which expands 70 mm. and is like many examples in the 

 writer's collection ; the last ventral segment is doubly notched and the 

 basal cell in the fore wing is clear. From the collection of the 

 University of Nebraska we have examined four males labeled British 

 Columbia (G. W. Taylor). From the collection of the Dept. of Agri. 

 Prov. of Nova Scotia, a male collected by W. Downes at Armstrong, 

 B. C, July 12, 1915; and from the collection of H. H. 'Lyman, a 

 female from North Bend, B. C, July 24, 1890. Prof. A. L. Lovett of 

 the Oregon Agricultural College, has kindly sent the following mate- 

 rial from the collection of that institution : Eureka, Wash., June 30, 

 1895, female; Rainier, Or., July, 1905, male (Thayer); Sauvier's 

 Island, Or., June 8, 1906, male (Farrell) ; Dixie, Wash. Co., Or., July 

 31, 1907, male; Oswego, Or., June 5, 1904, female (Ewing), June 8, 

 1907, female (George Ewing), July 7, 1907, female (George Ewing) ; 

 Willamina, Or., July 2, 191 1, female; Philomath, Or., Aug. 14, 1906, 

 female (Schrack); Corvallis, Or., June 2, 1906, male (Buchanan), 

 June 12, male, July 10, 1896, male, Sept. 2, 191 1, female, Sept. 9, 1906, 

 male (Woods) ; Cascadia, Linn Co., Or., male, July 28, 1903 (Rosen- 

 dorf), Aug. I, 1903, male (Rosendorf). Two females from Dilley, 

 Oregon, are in the writer's collection. 



Mr. Otto Huellemann of Wallace, Idaho, has sent me 51 speci- 

 mens of this species collected near his home, in the years 191 5 to 

 1918 inclusive. Three were collected in May, eight in June, and forty 

 in July. Judging from those received they were very plentiful in
