FAMILY TYPHLOCYBID.E. 



The members of this family may be easily recognized by the 

 four longitudinal veins or sectors of the elytra, which fork at the 

 base and run to the cross-nervures, forming the apical cells. 

 There are no anteapical cells in the elytra, nor is there a super- 

 numerary cell present in the hind wings. 



Genus Empoasca Walsh. 

 Generally small species, with the sectors of the posterior 

 wings ending in a marginal vein, and with one apical cell in the 

 hind wing. No appendix present on the elytron. 



Empoasca protea sp. n. (PI. X, Fig. 1). 



Color greenish yellow, with the green predominating. 



Length 2 mm. Breadth .5 mm. 



Face light yellow, fainter next the clypeus; gen«, lorse and clypeus 

 light green. Entire length of face exceeding the breadth by about 

 one-half of the former. Head somewhat large, slightly wider than the 

 pronotmn; vertex greenish, with irregular dark markings, and a faint 

 white line extending along the middle from the posterior to the anterior 

 margin; slightly elevated, giving a convex appearance. Anterior of 

 head angularly rounded, the angle less than a right angle. Eyes dark 

 green to black, large; width between eyes a little more than the length 

 of the vertex. Pronotum brownish green, with a faint white line on the 

 middle, running longitudinally from the posterior margin almost to the 

 anterior edge; two rather indistinct spots on either side of this line, 

 located on the anterior half; length of pronotum a little greater than the 

 vertex; anterior margin almost straight between the eyes, lateral 

 margins rounded, slightly convex above; twice as wide as its length. 

 Scutellum greenish brown, about equalling the pronotum in length; a 

 small transverse furrow near the apex. Elytra light green, translucent; 

 venation distinct. Hind wings with the marginal vein somewhat 

 produced. Abdomen yellowish, below greenish. Legs green, yellow 

 at coxse. Female genitalia: distinct green, last ventral segment 

 twice as long as the penultimate, sinuate and roundedly produced on 

 middle. Pygofers strong, twice as long as the width at base, ovipositor 

 a little longer. 



Described from three females. 



Habitat: Table Mountain, Cape Town (Mally). 



Empoasca heliophila sp. n. (PI. X, Fig. 2). 



Color yellowish, more or less tinged with green. Form long 



and slender. Length 3 mm. Breadth scarcely 1 mm. 



Face distinctly yellow, shading into greenish below, long and slender, 

 with the clypeus about one-third of the length of the frons. Cheeks 

 and lorffi greenish yellow; eyes pale green. Ocelli present, located on the 

 anterior margin of the head, brown in color. Vertex yellow, slightly 

 produced in front, its length less than the breadth between the eyes, and
