WEST COAST AND OTHER JASSID/E (HOMOPTERA). 



BY E. D. BALL, COLO. STATE COLLEGE, FORT COLLINS, COLO. 



Most of the material upon which the following descriptions are based 

 belongs to the National Museum, and the species are here described at the 

 request of the curator, Dr. W. H. Ashmead. 



Eutettix pannosa, n. sp. — Resembling saacia and scaber in general 

 appearance, smaller, darker, and with longer vertex and more generally 

 reticulate elytra. Length, $ 4.5 mm., $ 4 mm.; width, $ 1.5 mm., $ 

 1.25 mm. 



Vertex right angled, apex blunt, three-fifths as long as its basal width, 

 two- thirds as long as the pronotum, half longer on middle than against eye, 

 disc slightly sloping, flat, with the apex elevated. Face retreating, form- 

 ing an acute angle with the vertex, front rather broad. Elytra rather short, 

 compressed at the apex, venation weak, irregularly reticulate, the second 

 cross nervure sometimes present. 



Colour : vertex and pronotum pale cinereous or milky, heavily and 

 very evenly irrorate with brownish fuscous, except that the anterior margin 

 of the vertex presents six more or less definite dark spots, and the lateral 

 margin of the pronotum is narrowly lined with ivory white. Elytra with 

 the inner halves resembling the pronotum in colour, the outer half on either 

 side milk white, with more or less of brownish reticulation, especially along 

 the costal margin. The brown area on the disc being heaviest along the 

 margin, and shading out towards the suture, the milk white area being 

 continuous with that on the margin of the pronotum and including the 

 claval suture to just before the middle, when it narrows down obliquely to 

 one-half the former width, and becomes obscured by the heavier reticula- 

 tion toward the tip. Face closely and evenly irrorate with fuscous. 



( ienitalia : female segment twice the length of the preceding posterior 

 margin, rounding with a rather broad, blunt, slightly bilobed median 

 projection, surface of the segment depressed either side of this tooth ; 

 male valve triangular, narrower than the ultimate segment, and about 

 two-thirds its length ; plates long, triangular, apices acute, three times the 

 length of the valve. 



Described from eight specimens from the National Museum collec- 

 tion, " Los Angeles Co., California, Coquillett collector." 



Eutettix fe?iestrata, n. sp. Form of pullata nearly resembling 

 jucunda, but more clearly marked. Longer and narrower than either
