South African GrassJiopjh'vs. 107 



Described from the female type and a male paratype from 

 Lainf^shur};, Cape Province, 3. x. 1917; one male from 

 Spitzkop, ]>iirkley West, Cape Province, 15. xii. 1917 ; one 

 male from Beaufort West, 25. iv. 1917; and one female 

 from Dei-lfontein {Col. Slo(/(/ftt). 



This species is closely related to -S'. forbesl, Burr, fi-om 

 Sokotra, but easily distinguished from it by the reticulation 

 of tlie elytra, apart from the coloration of the wings. 



5. Acrotylus nigripennis, sp. n. 



^. Small, but not slender. Antenna? nearly twice as 

 long as the head and pronotum, somewhat flattened, dis- 

 tinctly thickened towards the apex. Head distinctly 

 prominent above the pronotum, slightly reclinate. Frontal 

 ridge sulcate tlirongiiout, exce])t near the clypeus ; its sulcus 

 separated from the fastigial impression by a feeble keel ; its 

 margins gradually divergent from the fastigium towards the 

 median ocellus, slightly appi'oximated and parallel below the 

 ocellus and divergent, but gradually disappearing towards 

 the clypeus; the ridge at the ocellus is twice as broad as at 

 the fastigium and distinctly narrower than the Avidth of the 

 vertex between the eyes. Temporal foveola; flat, triangular, 

 longer than «i(le. Fastigium of the vertex strongly slojjing, 

 distinctly depressed, about twice as long as broad ; its lateral 

 carinic sinuate ; the apex trapezoidal, truncate. Eyes 

 slightly prominent above the vertex, oval, slightly higher 

 than long, and their height subequal to the height of the 

 subocular space. Pronotum not longer than its width at 

 the shoulders, strongly constricted in the prozona, distinctly 

 sellit'orni, with two bread and shallow postocular impres- 

 sions ; the disc in the prozona ctnivex, with a scarcely 

 indicated first transverse sulcus and almost imperceptible 

 median keel ; the typical transverse sulcus placed in the 

 middle, not very distinct ; metazonal disc very feebly convex, 

 with the median keel low ; hind margin widely rounded ; 

 lateral lobes much higher than long, rather strongly im- 

 pressed between the sulci; their fore margin bisinuate; the 

 lower margin widely rounded in the hind half; the fore 

 angle very obtuse, rounded ; the hind atigle very widely 

 rounded. Mesosternal lobes strongly transverse ; tlieir 

 inner margins oblique, divergent posteriorly ; the hind 

 margins not parallel to the fore margins; the inner angles 

 very obtuse ; mesosternal interspace strongly transverse, as 

 wide as one of the lobes, distinctly widened posteriorly. 

 Metasterual lobes separated by an interspace about as long
