Synopsis of Species. 



Head and prothorax black ; elytra pale yellow, mth a broad 

 dorsal fuscous band on each side Promontorii. 



Prothorax broadly flavescent all round ; elytra with a short 

 narrow fuscous band on each side capensis. 



Pachyteachelus Promontoeii. 



Head and prothorax black, the anterior and basal margins of the 

 latter sometimes narrowly rufescent ; palpi and the three basal joints 

 of antenna3 flavescent, the other joints infuscate ; clypeus with two 

 small tubercle-like protuberances in the basal part ; head deeply 

 impressed longitudinally along the ocular ridge and impressed across 

 the vertex, posterior part smooth ; prothorax nearly as broad as long, 

 nearly truncate at both ends, with the outer sides nearly straight, 

 convex, narrowly grooved longitudinally from apex to base, impressed 

 on each side of the median groove near the base, which is closely 

 but narrowly punctured from one impression to the other ; body not 

 pedunculate ; elytra not broader than the prothorax, subcylindrical, 

 narrowly striate with the intervals smooth, flavescent with a broad 

 fuscous dorsal band extending on each side from the first to the fifth 

 stria, and disconnected from both base and apex, the scutellary 

 region and the outer margin are also infuscate ; under side piceous 

 red; legs pale flavous with the knees infuscate. Length 6-7 mm. ; 

 width 2-2 J mm. 



Hah. Cape Colony (Cape Town). 



Found burrowing in wet sandy saline spots under water algag. 



Pachyteachelus capensis. 



Size, facies, and sculpture of the preceding species, but the head 

 is not transversely impressed on the vertex ; the prothorax is only 

 infuscate in the median part, the fuscous dorsal patch on each 

 elytron reaches from the second to the fourth interval instead of the 

 first, and is very short on the fifth interval if it invades it, the colour 

 of the background is also more testaceous red, as are the legs also. 

 Length 6-7-|- mm. ; width 2-2 J mm. 



Hah. Zambezia (? Zambeze Eiver). 



This species may, however, prove to be only a varietal form 

 of P. Promontorii. 



Gen. AGEIODUS. 



Mentum broadly emarginate, semicircular, with the apical part of 

 the lobes very sharp ; ligula narrow, parallel, truncate at the tip, and 

 bearing a long seta at each apical angle ; paraglossse also parallel and 

 truncate, very slightly broader than the ligula, and disunited from it 

 at some distance from the tip, slightly diverging and glabrous, last joint
