seum there is a male from Santa Cruz Mts., Calif., that appears to 

 belong to this species. It bears a label "New to Uhler, 1893." The 

 lighter colors on the head, pronotum and mesonotum are much more 

 extended than usual. The tergum is black; the uncus is the same as 

 in canescens.

1918. Journal N. Y. Ento. Soc, xxvi, p. 153, pi. 8, figs. 4-5. 

 This species was described from a male and female from O'Reilly, 

 Mississippi, and so far they are the only specimens known. Its green 

 color and size will serve at the present time to separate this remark- 

 able insect from the other species of the genus. 



Okanagana aurantiaca Davis. 



1917. Journal N. Y. Ento. Soc, xxv, p. 9, pi. 2, fig. 4. 

 The three males and one female from which this orange and black 

 species was described are supposed to have come from Lower Cali- 

 fornia, Mexico. No additional specimens have been seen. 



Okanagana fratercula Davis. 



1915. Journal N. Y. Ento. Soc, xxiii, p. 20, pi. 3, fig. 5. 

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

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

 Co., Utah. The following are additional records: Kolb Mts., Wash- 

 ington Co., Utah, 8,500 ft., June 30, 1917, male (George P. Engel- 

 hardt), Davis collection; Nephi, Utah, June 25, 1912, male (Dr. E. D. 

 Ball), Davis collection; Blackfoot, Idaho, June 22, 1904, male (E. S. 

 G. Titus), U. S. National Museum; Springfield, Idaho, July 24, male 

 and female (H. Skinner), Acad. Natural Sciences, Philadelphia; 

 Reno, Nevada, June 6, 1909, two males (Dr. E. D. Ball), Davis col- 

 lection; Iron Springs, Cedar City, Iron Co., Utah, June 26, 1919, 5, 750 

 ft., three males and twelve females (T. Spalding) ; Coal Creek, Iron 

 Co., Utah, June 27, 1919, male (T, Spalding), Davis collection. The 

 specimens from Nevada and Iron Co., Utah, may belong to a distinct 

 and larger species with wing expanse as great as 65 mm. They have 

 the front wings beautifully colored. The veins surrounding the mar- 

 ginal cells and first ulnar cell, are very dark, the remaining veins are 

 bright yellow, and the basal cells is blackened. The tergum is blacker 

 than in typical fratercula, segments seven and eight being the only
