 a row of lateral spots on the abdomen. 



One ? from the Kassai district, Congo Free State (Taymaus). 



l'^. Acorynus pais spec. nov. 



?. Black, tomentnm olivaceon.'< ; antenna, tibiae and tarsi reddish. Eye 

 bordered by a yellowish grey stripe; on pronotnm three narrow vittae of the same 

 colour ; alternate interspaces of elytrae olive-grey, more or less interrupted, some 

 dashes of the same colour in tlie other interspaces; a lateral 8tri])e on prostemnm 

 and the tip of metepisternum more densely pubescent than rest of underside, which 

 is grey. 



Rostrum similar to that of A. calcaratxs .lord. (1804), but narrower proxi- 

 mally, with three dorsal carinae which do not reach the apex, wliile the median 

 one extends on to the head ; edge of antenna! groove continued by carina, which 

 soon forks, one branch ending below the eye and the other being parallel with the 

 dorsal carinae but much more feebly developed than in ,1. cd/rarati/s. Eye smaller 

 than in ? of calcarcitits, the frons being one-third the width of the rostrum at its 

 narrowed point. Antenna! segment 10 less than half the length of 11, the latter 

 longer than 9. 



Prothorax conical ; dorsal carina straight, towards the sides feebly fle.xed 

 backwards and in a rather sharp curve forward, as in ,1. calcarutus, the lateral 

 carina not slanting downward as in ,1. (jeometi-icus Jord. (1894), but being parallel 

 with the dorso-lateral vitta. 



Elytra strongly elevate near the base, the basal portion of the suture appearing 

 depressed. 



Legs not ringed or spotted. 



Length (exclusive of head) .') mm. 



One ¥ from Portuguese Congo. 



19. Acorynus caffer spec. nov. 



?. Probably a local form of -4. calcaratus Jord. (1894); bnt the question can 

 hardly be decided before the S of cafer is known. Frons more convex than in 

 calcaratus. Sides of head below eyes and a broad border to the eyes yellowish 

 grey ; this border continnons with a broad, obli(iue, ill-defined, dorso-lateral, 

 pronotal vitta, there being also a vestigial median vitta on the ])ronotuni ; 

 dorsal carina sharply angulate in centre, curved backwards sublaterally as in 

 calcaratuH aud then curved forward in a wider cnrve than in that species. 

 Alternate interspaces of elytra more strongly convex than in calcaratus, the 

 basal and apical margins yellowish grey, short lines or spots of the same colour 

 behind the base and behind the middle, arranged transversely. Pygidium truncate, 

 with the corners rounded. 



Shaft of antenna rufescent, segment 1 rufous, 8 pale rufous. 



Chie ? from Malvern, Natal. 



20. Litocerus helictns spec. nov. 

 i. Black. Rostrum vertical, on a plane with the frons and almost at right 

 angles to the occiput, broad, twice as lung as it is broad, almost suddenly widened 

 in centre, where the antennal grooves terminate, resembling the rostrum of the
