Abdomen.—There are no dorsal processes as in A. capensis n. sp., but there is a median grooved appendage developed below and between the cerci which is not present in A. capensis. Viewed ventrally, this. *A 1A Fig. 5.—Aphanicerca denticulata n. g. et sp. Fore-wing. Length 5-7 mm. Venational notation as in fig. 1. appendage is scissors-shaped (fig. 6a), with the two loops placed posteriorly and the narrow process projecting anteriorly ; the sides of this latter are markedly denticulate. The paraprocts are much larger, their forward processes weakly chitinized, double. Cerci shorter and stouter than in A. capensis, hairy. Subgenital plate very short, basal appendage minute. Wings (fig. 5) almost unicolorously tinged with brownish fuscous, slightly darker at base and along costa of fore-wing. Venation closely similar to that of A. capensis, but with Sc arching up distally to end in costa exactly at the point where the transverse cross-vein descends to the transverse cord. Cu2 not quite as long as in A. capensis, in fore-wing ; in hind-wing the distal intercubital cross-vein is placed nearer margin of wing than base of transverse cord. $ unknown. Type.—Holotype male, mounted on slide, body treated with KOH, wings cleared and mounted separately, from specimen preserved in alcohol, taken on Winterhoek Mountains, Tulbagh, by K. H. Barnard, August 1929. Aphanicerca barnardi n. sp. (Figs. 66, 7-9.) c£. Total length, 5 mm. ; fore-wing, 5-4 mm. General colour brownish. This species is evidently closely allied to A. denticulata.
