Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 303 



Color of body yellowish to dark greenish in places in the female ; the 

 apex of the tibise and the tarsi often of a bluish green. In strongly col- 

 ored examples the front shows a broad whitish median longitudinal vitta 

 and base, and on the vertex a whitish band next the eyes, a narrower 

 longitudinal one on the middle and an oblique transverse one either side 

 at apex. Pronotum with three white spots on the anterior margin, the 

 median often continued as a fainter median vitta to the apex of the scu- 

 tellum. Elytra uniformly milky-hyaline, scarcely tinged with dull green in 

 the female, not at all in the male, the commissural and sutural nervures of 

 the clavus slenderly fuscous. Apex of the elytra with a smoky cloud in the 

 female which may cover much of the surface in the male. Wings milky- 

 hyaline with fuscous nervures. Abdomen blackish in the male, narrowly 

 margined with yellow, dull green in the female. 



Described from six male and seventeen female examples 

 taken by Mr. Giffard at Summit, Placer Co., August 24, 1916, 

 at 7000 feet elevation. Immature examples of smaragdula 

 show indications of the white marks on the head and pro- 

 notum and they sometimes are absent in the females of this 

 species, but the elytral characters are constant in suhlactea 

 and the male genital characters are obviously distinct. That 

 this type material is mature is evident by the presence of the 

 pruinose spots on the elytral costa in some males. 



Holotype (No. 369), male, in collection of the California 

 Academy of Sciences. 



Allotype, female, in collection of Mr. Giffard. 



Paratypes in both collections and in that of the author. 



303. Empoasca transversa, new species 



Aspect of a small dark aurcoviridis ; dark greenish, elytra bifasciate 

 with dusky. Length 4'/4 - 5 mm. 



Head with the eyes distinctly broader than the pronotum. Vertex 

 shorter and broader than in trifasciata. Hind margin of the pronotum 

 moderately concave, nearly truncate in trifasciata. Last ventral segment 

 of the female considerably produced, the sides moderately sinuated, much 

 as in aurcoviridis ; in trifasciata shorter with the sides scarcely sinuated. 

 Twisted apex of the male plates very broad, membranous, almost spatulate. 

 Pygofers distorted in the specimen before me, but apparently produced 

 as in aureoviridis. 



Color dark dull green, becoming blue green on the legs, apex of the 

 abdomen and extreme base of the costa. Face and vertex marked with 

 white as in snblactea and aureoznridis. Anterior margin of the pronotum 

 with three white spots, usually distinct, the intermediate produced in a 

 median pale line which may cross the scutellum. Elytra with a faint 

 transverse fuscous band crossing the middle of the clavus and another on 

 the apical areoles, neither attaining the costa, the apical beginning at the 

 tip of the clavus and interrupted by the pale nervures. Tergum inclined 

 to golden green. 



Described from one male taken by Dr. J. C. Bradley at 

 Leona Heights. Alameda Co., in August, 1908. and six fe-
