faces. Genitalia: last ventral segment black on middle, yellow at the 

 sides; little longer than the penultimate; valve black at base, yellow on 

 border, scarcely visible; plates whitish long, somewhat romided at the 

 tips; pygofer a little longer than the plates. Legs light yellowish white. 



Described from four males and four females. 



Habitat: Cape Town (Mally). 



The species described above is subject to some variation 

 in the distribution of the brown coloration of the face, vertex 

 and abdomen. In some, the black marking on the vertex is 

 absent, in others very prominent; in others the black on the 

 face extends all over except for the middle of the frons and 

 cheeks and loras, while it may be wanting in some other 

 specimens. 



Athysanus eriocephalus sp. n. (PI. VII, Fig. 3). 



General color light yellowish to brownish. Length 4 mm. 

 Breadth 1.5 mm. 



Female — Color yellowish brown, with the vertex a dirty white, 

 marked with irregularly shaped brown markings. Head strong, the 

 vertex somewhat produced, with the anterior margin rather sharp, 

 and the apex angular; length of vertex a third greater than the pronotum, 

 and less than the width between the eyes, equalling about two-fifths 

 of the total width across the eyes. Eyes black, prominent; ocelli 

 located near the eyes. Face strong, the frons marked by numerous 

 transverse brown arcs, about one and a half times as long as its width 

 a little above the clypeus; the latter about one and a half times as 

 long as its breadth, the margins subparallel; frons about two and a half 

 times as long as the clypeus; lorae not quite as wide as the clypeus. 

 Pronotum a dirty white with brownish markings, narrow, about three 

 times as wide as its length, the anterior margin broadly rounded, the 

 lateral margins short. Scutellum not quite as long as the pronotum. 

 Elytra yellowish white, with occasional brownish spots, veins showing 

 as brown lines; brown spots on the middle anteapical cell, the first 

 discal cell, and two on the second discal cell; margins well rounded. 

 Abdomen above brownish black, beneath brownish yellow. Genitalia, 

 last ventral segment about one and a half times as long as the penulti- 

 mate; posterior margin deeply emarginate, color yellow, the pygofers 

 brownish, much wider at the base than the tip. Ovipositor blackish, 

 strong, a little longer than the pygofers. 



Male — Lighter than the female, in fact a light straw color; elytra 

 lighter, otherwise resembling the female. Genitalia: Last ventral 

 segment brown on the middle, whitish yellow at the sides, almost 

 one and a half times as long as the penultimate; valve small, semi- 

 circular, scarcely visible; plates yellowish brown, almost as long as last 

 ventral segment; pygofer a little longer than the plates. 



Described from two females and five males. 

 Habitat: Cape Town (Mally).
