Okanagana schaefferi Davis. 



1915. Journal N. Y. Ento. Soc, xxiii, p. 19, pi. 3, fig. 4. 

 This species was described from a single male in the collection of 

 the Museum of the Brooklyn Institute of Arts and Sciences, from 

 Iron Co., Utah, 1904. In June, 1917, Mr. George P. Engelhardt of 

 the Brooklyn Museum collected a number of specimens in the foot 

 hills of the Kolob Mts., Washington Co., Utah, and kindly gave me 

 seventeen males and two females. Other specimens examined have 

 been a male, Manti, Sampete Co., Utah, June 23, 1903, collection Dr. 

 E. D. Ball, a male from Salida, Colorado, June, 1885, collection 

 University of Nebraska, and a female from Jemez Springs, 6,400 ft., 

 New Mexico, June 17, 1919 (J. Woodgate). A noticeable feature of 

 this large insect is the strongly protruding front of the head.

This species was listed as a synonym of rimosa Say by Distant in 

 his Synonymic Catalogue of Homoptera (1906), but it is distinct from 

 that species, and from Okanagana bella described in this paper, which 

 it more closely resembles. The most noticeable differences between 

 these three species have been mentioned in. the table, and in series 

 occidentalis is not as blue-black as bella, and the pubescence on the 

 upper surface is more abundant and more golden in color. The true 

 rimosa is a duller colored insect, the tergum not shining as in occi- 

 dentalis and bella. Walker's description is poor and we may be in 

 error in applying it to this species. The description would also apply 

 to some specimens of vanduzeei except that they are usually too small. 

 He states that the body is, 12 lines in length, is black, and that the 

 mesothorax has two V-shaped testaceous marks, " which extend from 

 the fore border to the disk, and are distinct except at the tips." These 

 V-shaped marks are commonly present in what we have called occi- 

 dentalis, and the tips are usually well defined. In bella the V-shaped 

 marks are obscure or absent. 



John Keast Lord in The Naturalist in Vancouver Island and Brit- 

 ish Columbia, has this to say of this species : " But there was one 

 sound — song perhaps, I may venture to call it — that was clearer, 

 shriller and more singularly tuneful than any other. It never ap-
