Okanagana balli looks something like a small riniosa, but is more 

 yellow in color, and the transverse fold crossing the fore wings at the 

 node is sometimes developed, as it is in synodica. 



The first specimen I examined of this species came from Dr. O. S. 

 Westcott, Oak Park, III, but was without locality or date label. In 

 the U. S. National Museum there is a female labeled Winona, Minn., 

 and in the Uhler collection in the same museum, there is a male from 

 Greene Co., Iowa, labeled " Tibicen n. sp., Stal." In Prof. Albert P. 

 Morse's collection there is a male labeled Little Rock, Iowa, and Dr. 

 E. D. Ball has sent to me fifteen males and one female from Little 

 Rock, Iowa. It is evident that at the time they were collected they 

 appeared as a swarm, but unfortunately they bear no date. In the 

 collection of the University of Minnesota there is a male labeled 

 Rock Co., Minn., June 24, 1910, and four other males without locality 

 labels. In the collection of the South Dakota State College, there 

 are five males and two females labeled Brookings, S. D., and a male 

 and female labeled S. D. These and the specimens mentioned above 

 closely resemble one another in size and markings.

The following records are additional to those given in the original 

 description: Sonoma Co., Calif., July 4, male (O. Sack), U. S. Nat. 

 Museum. The label further states, " Its note is continuous (not in- 

 termittent) and not loud. It resembles the whirring of a bee in 

 confinement." Hullville, Lake Co., Calif., June 13, 1917, two males, 

 three females (Dr. F. E. Blaisdell). Ukiah, Calif., May, 1919, three 

 males (E. P. Hewlett). Keddie, Plumas Co., Calif., 3,500 ft., June 

 24, 1918, two males, and June 28, 1918, male and female (Frank M. 

 Jones). In transmitting these specimens and a twig in which a 

 cicada had oviposited, Mr. Jones writes : " The red cicada, of which 

 there are four examples, was locally abundant and in constant song 

 in the manzanita bushes, and the manzanita twig showing egg-deposit 

 almost certainly belongs to this species, though I did not see the 

 female at work." 



The female of this beautiful insect has never been described. The 

 one collected by Mr. Jones expands 64 millimeters and is of the same 

 color as the type; the body black above covered with short reddish
