1922] Olsen: Cicadella of North America 361 



bluish and somewhat shining color will readily separate it from 

 hieroglyphica while the light markings of the vertex will serve 

 to distinguish it from dolobrata. 



Described from eighteen males, specimens all from Arizona. 

 Five males from "Phoenix, Arizona, R. Kunze Collection" 

 American Museum of Nat. Hist, collection; seven males from 

 "Phoenix, Arizona, R. Kunze Collection"; and one male from 

 "Phoenix, Arizona, 6-1-02," H. G. Barber Collection. Two 

 males from "Arizona C. U. Lot. Cornell U .Lot 411 and 414," 

 one male from "Arizona U. Lot P. R. Uhler Collection," col- 

 lection of United States National Museum. In time, it may 

 prove to be a perfectly good species. This can better be ascer- 

 tained when the female becomes known. At present the rank 

 of sub-species will serve every purpose. Male holo-type and 

 three male para-types in The American Museum of Nat. Hist. ; 

 four male para-types in Mr. H. G. Barber's collection; four 

 male para-types in U. S. Nat. Mus. Coll. ; six male para-types 

 in author's collection. 



Cicadella hieroglyphica sub-species barberi n. sub-sp. 



Small, slender, pale yellowish-green, scarcely marked. Vertex, 

 anterior pronotum, scutellum, costal margins of the elytra and all 

 beneath from a pale straw-yellow to a slight greenish-yellow. Vertex 

 with apical black spot, disk very lightly marked with fuscous, pattern 

 scarcely discernible, in some specimens entirely obliterated, leaving 

 the vertex clear yellow with only the eyes, ocelli and apical spot dark. 

 Pronotimi without maculation, posterior disk yellowish-green. Scutellum 

 with faint traces of maculations. Elytra yellowish-green. Face and 

 all beneath pale straw color, immaculate or slightly marked. Veins 

 usually pale in the females. 



Four females, from "Phoenix, Arizona," American Mus. of 

 Nat. Hist. Four females, ' ' Phoenix, Arizona, May 25, to June 8, 

 1902," H. G. Barber Collection. One female "S. Col." One 

 female, "Pecos, New Mexico, August 11, Ckll.," and one 

 female, "Santa Fe, New Mexico, Ckll.," United States Nat. 

 Mus. 



Seven males from "Glen, Sioux Co., Neb.," H. G. Barber 

 Collection and one male, "Col. Aug. Uhler," U. S. Nat. Mus. 

 Collection, may possibly be referred to this sub-species; they 

 have a trifle more markings on the vertex than the females as 

 above described and also the veins of their elytra are set off 

 with a darker color.
