Show 1906.] NEW AFRICAN CURCULIONID/E. 943 A plemonus z iz y p i i i , sp. nov. (Plate LXVII. fig. 11.) Long. 3-3|, lat. 1|-H mm. Head porrect, elongate, subcylindrical, coarsely punctured except on extreme vertex, with a shallow impression between the eyes, black with a few sparse white depressed set* ; eyes lateral, round, subdepressed. Rostrum stout, subcylindrical, narrower, but a little longer, than head, not curved, but slightly deflected ; upper surface coarsely punctured throughout and with depressed white set*, except at extreme apex, which is smooth and shiny. Antennae black, inserted behind middle. Prothorcix longer than broad, truncate at apex and base, cylindrical, with a slight constriction near apex ; upper surface convex, coarsely and evenly punctured, with a deep elongate median fovea at base ; colour black, with sparse depressed white set*. Elytra pyriform, much broader than prothorax at shoulders, which are obliquely prominent, sides strongly rounded, broadest well behind middle; upper surface very convex, gibbous, deepest behind middle, the posterior declivity very steep, with nine broad and dee}) stri* containing row's of strong punctures ; the intervals broad and plane, coarsely coriaceous, and often with a faint central stria, but with no tubercles or carin* ; colour black, occasionally with a dark reddish tinge, with sparse depressed white set*. Legs stout, black, punctate, and with scattered white set*. N atal : Malvern (C. iV. Barker), Estcourt (G. A. K. M.). M ashonaland : Salisbury (G. A. Iv. M.). Type in the British Museum. This insect feeds on various species of Zizyphus, as also does its congener A. gibbipennis Falir. This latter species has a very different appearance, owing to the elongate tubercles on the intervals of its elytra. A. aurivillii Fst. (Stett. ent. Zeit. xlix. 1888, p. 296-type in the Stockholm Museum) from Damaraland is very closely allied to gibbipennis, and differs only in its smaller size and in having the rostrum parallel-sided and not constricted at base. EuOPS CYAN'EUS, Sp. 110V. Long. 3, lat. 1| mm. Head subconical, dark blue, convex 011 vertex, and with distinct scattered punctuation ; eyes brown, large, prominent and broadly united above. Rostrum a little longer than head, narrow at base and strongly dilated from there to apex, convex above, dark >lue, closely and distinctly punctured; antenn* black, quite similar to those of E. morio Boh. Prothorax about as broad as long, sides slightly rounded, broadest rather behind middle, apical margin broadly rounded, much narrower than base, which is isinuate and has a distinct narrow margin ; upper surface very convex, dark blue,^ very shiny, evenly set with fine scattered punctuation and without any central furrow or carina. Elytra subquadrate, jointly sinuate at base, much broader than prothorax at shoulders, which are roundly prominent, sides straight, |
