Some new Species of Athysanus and Related Genera 



(Homoptera). 



By E. D. BALL, Logan, Utah. 



(Continued from page 176) 



Platymetopius trilineatus n. sp. 



$ . Resembling slossoni in general appearance but much larger and 

 with a dark face and a longer and definitely trilineate vertex, in the 

 male. Length 5 mm. 



Vertex longer than in the male of any known species, three times 

 as long as basal width or length of eye, face definitely concave in 

 profile. Elytra narrow, appressed, outer anteapical definitely shorter 

 than the central one. Third apical cell very broad with a partially 

 formed supernumerary cell at base. Male valve enlarged, gibbous, 

 the margin concave to just before the blunt rounding apex, plates 

 together broader than valve or pygofers, lateral margin concave at 

 base, then slightly convexly rounding to the broad blunt slightly 

 divergent apices, extending one-third their length beyond the valve and 

 slightly exceeded by the stout pygofers. 



Color: milky white and pale brown, similar to slossoni, vertex with 

 a definite median white stripe extending nearly half-way back from 

 apex and two of equal width arising just outside of this at apex and 

 extending back just inside the black margin to just before the end of 

 the median stripe where they almost articulate with a pair of slightly 

 curved stripes and which in turn articulate with a pair of narrow 

 approximate lines at the base, the whole forming an almost continuous 

 pair of light lines from apex to base curving outward on disc. Re- 

 mainder of surface composed of alternate black and white vermicula- 

 tions, washed with brown at the base. Pronotum and scutellum 

 irrorate with light brown, seven stripes on the former and the apical 

 dots on latter white. Elytra milky white, the nervures brown, the 

 apical and costal ones black, whole surface irrorate with pale brown 

 except the sutural and costal margins, circular spots alongside all cross 

 nervures and the narrow margins next the nervures. Face uniformly 

 irrorate with brown and scarlet, omitting a white line under the 

 vertex margin set off by black vermiculations. 



Described from two males taken at Pasadena and Santa 

 Margarita, California, by the writer. The exceptionally long 

 trilineate vertex will at once separate this species from all 

 others except slossoni, from which the dark face and widely 

 different genitalia will at once distinguish it.
