Okanagana mercedita Davis. 



1915- Journal N. Y. Ento. Soc, xxiii, p. 16, pi. 3, fig. 8. 



Only the type, the allotype and 16 males and 14 females from 

 Merced Co., California, June 18, 1914, have been examined. 



The short marginal cells in the fore and hind wings of this species, 

 also in O. minuta and Tibicinoides ciipreo-sparsus suggest a close re- 

 lationship, and we think that they will ultimately be associated in the 

 same genus. The supplementary transverse vein at the node is also 

 more developed in mercedita and minuta than in most species of 

 Okanagana, though not quite as well defined as in cupreo-sparsus, the 

 type of the genus Tibicinoides. 



Okanagana minuta Davis. 



1915- Journal N. Y. Ento. Soc, xxiii, p. 17, pi. 3, fig. 6. 

 The original description was based on the type and 11 paratypic 

 males, all from Sanford University, California, May 26, 1914 (C. H. 

 Kennedy), and a female, Fresno Co., California (J. C. Bradley). Mr. 

 Alonzo C. Davis has sent me three males collected at Lebec, Kern 

 Co., Calif., June, 1918.

This small, beautiful, black and red species has been included in 

 the table as an aid to the identification of species, and as has already 

 been stated, probably Okanagana mercedita and O. minuta should be 

 transferred to the genus Tibicinoides. The types mentioned by Uhler 

 were two females captured near Los Angeles, California, by D. W. 

 Coquillett. 



The following specimens are in the writer's collection, all from 

 southern California: San Diego Co., May 6, 1914, two males, and 

 May 24, 1914, three males (E. P. Van Duzee) ; San Diego, July, 1914, 

 three males (Prof. W. S. Wright) ; La Jola, June 10, 1915, three 

 males (B. B. Fulton) ; Dulzura, San Diego Co., June 13-21, 1917, 

 twenty males (Prof. W. S. Wright). In the collection of Dr. E. D. 

 Ball, there is a male collected at Ontario, San Bernardino Co., June 

 12, 1908. 



In the Transactions of the San Diego Society of Natural History, 

 Vol. 2, p. 48, November, 1914, Mr. Van Duzee comments on this 

 species as follows : " This very pretty little species was abundant this
