white, the frons brownish on the middle and sides, with a brown band 

 extending from below the ocelli to the anterior margin of the head; 

 much wider than the clypeus, which is oval in shape, yellowish, with 

 the sides marked brown; loree white, not as wide as the clypeus. Cheeks 

 white, strong and broad. Ocelli colorless. Black markings beneath 

 the antennal pits. Pronotum strong, brownish on anterior, whitish on 

 posterior half with two large black spots near the posterior margin; 

 irregular brown markings in advance of these, and a brown median band. 

 Pronotum almost twice as wide as its length, the anterior margin 

 rounded, and the posterior broadly rounded towards the sides; convex 

 above. Scutellum yellow, with a brownish semi-circular furrow on the 

 anterior half, not as long as the pronotum; apex tapering to a fine point. 

 Thorax beneath black. Elytra gray, semi-transparent, the veins dis- 

 tinct, showing as brown lines. Middle anteapical cell much larger and 

 longer than the other two; only three apical cells present. Abdomen 

 above yellow, black at the base, beneath light yellow. Legs light yellow 

 to whitish. Genitalia: male — last ventral segment a little longer than 

 the previous ones; valve strong, three times as long as the ultimate 

 ventral segment, broadly triangular in shape, rounded at apex; plates 

 triangular, about equalling the valve in length. Pygofers not as long as 

 the plates, yellowish ventrally, black dorsally. 



Described from two males. 



Habitat: Cape Town (Mally). 



This species may be easily distinguished from A. novella 

 Say. by the size and shape of the pronotum. In the former 

 the pronotum is much larger and more convex than in the 

 latter. Further the black spots on the pronotum of A. novella 

 are located nearer the middle than in this species. 



Agallia cuneata sp. n. (PI. V, Fig. 2). 



Form thin and slender with the posterior end of the body 

 distinctly wedge-shaped. Color light pink, obscured in parts 

 by a white incrustation ; large round, black spots on vertex and 

 pronotum. Length 3.5 mm. Breadth scarcely 1 mm. 



Vertex small, well rounded, pinkish, the black spots on the anterior 

 margin surrounded by yellowish halos; length about one-fourth as long 

 as the pronotum; anterior margin rounded. Eyes yellowish, ocelli black 

 Face narrow, a little longer than broad; frons whitish, with brown across 

 the middle, and on the sides to the clypeus; genae almost straight mar- 

 gined from clypeus to the eyes ; lorse rather long and narrow, not as wide 

 as the clypeus, which is short and oval, its length about one-fourth of 

 the frons; sutures marked indistinctly with brown in parts. Pronotum 

 whitish pink, about one and a half times as broad as its length, and not 

 as wide as the vertex across the eyes ; convex above both anteriorly and 

 laterally; anterior margin rounded between the eyes, side margins of
