Last ventral segment of female yellow, a little longer than the penulti- 

 mate; pygofer yellow, ovipositor black, equalling the pygofer in length. 

 Male: Color whitish, valve short, somewhat angular; pygofer longer 

 than the plates, which are triangular. 



This insect is here recorded from South Africa for the first 

 time. It is widely distributed over Europe and North America, 

 having attracted considerable attention on those two continents 

 because of its economic importance. Osborn places it among 

 the six most important leafhoppers affecting cereal and forage 

 crops in the United States. Its occurrence in South Africa is 

 interesting, in view of the attention which it has attracted in 

 other countries. 



Habitat: Cape Town (Mally). 



Cicadula longiforma sp. n. (PI. XI, Fig. 3). 



Form long and slender, resembling a Gnathodus to some 



extent. General color light yellow. Length of female 4.25 



to 4.5 mm. ; male 4 mm. Breadth 1 mm. 



Vertex yellow, narrow, rounded anteriorly; two light brownish arcs 

 on the anterior margin, a small longitudinal line on the iniddle, extending 

 from the posterior margin; length about one-third of the width between 

 the eyes. Face generally yellowish brown, with the cheeks lighter in 

 color; frons twice as long as its width, and three times the length of 

 the clypeus, with six arcs traversing its surface; cheeks rather broad, 

 equalling the frons in width ; clypeus about one and a half times as long 

 as its width and about as wide as the lora. Eyes large and prominent, 

 black below and grayish above; ocelli dilute brown, located close to the 

 eyes. Thorax well developed, the pronotum three times as long as the 

 vertex; slightly convex on the middle; color light yellow with many 

 irregular and indistinct brown markings on the anterior half; anterior 

 margin well rounded between the eyes, the posterior straight. Scutellum 

 yellowish, with a few irregular faint brown spots, basal angles of a 

 deeper hue than the apex, more than half as long as the pronotum, with 

 a distinct transverse line on the middle. Elytra long, much longer 

 than the abdomen, faint yellow, transparent; length exceeding the 

 abdomen by the distance from the apex of the claval suture to the 

 apex of the membrane. Abdoinen above brownish, yellow at the 

 lateral margins; beneath yellow, interspersed with black. Legs light 

 yellow with the tarsi brown. Genitalia: Female — -last ventral segment 

 longer than the penultimate, emarginate, convex; pygofers long and 

 narrow, widely separated at the base, about twice as long as the last 

 ventral seginent and about one and a half times as long as the width at 

 base; ovipositor equalling the pygofers in length, rounded at the tip. 

 Male: Last ventral segment large, longer than the preceding; valve 

 thick, shorter than the last ventral segment; plates long and narrow at 

 the tips; pygofers longer than the plates. 



Described from two males and two females. 

 Habitat: Cape Town, C. P. (Mally).
