216 Mr. W. L. Distant on African Pentatomidse. 



Fairm., from Abyssinia, but at once separated by the 

 antennae and the strongly crenulate jet-black costal margin 

 to the corium. 



Tantfa, gen. nov. 



Head long, triangular, obliquely narrowed to apex, as long 

 as breadth at base (including eyes), lateral lobes longly 

 passing central lobe, their apices subacute ; anteunae with 

 the second and third joints subequal in length, fourth a 

 little shorter than fifth ; pronotum about half as long as 

 breadth between the lateral angles, from between which it is 

 deflected towards apex, the lateral margins denticulate, the 

 lateral angles shortly angularly subspinous ; scutellum as 

 long or slightly shorter than head and pronotum together, 

 attenuated from about one-third from apex ; corium about 

 as long as breadth between pronotal lateral angles ; mem- 

 brane reaching abdominal apex ; other characters generally 

 as in Me tony mi a and Dalsira, from which Tantia is at once 

 separated by the structure of the head, which character taken 

 by itself allies it to Schismatops.

Hab. Congo. 



Magwamba, gen. nov. 



Body elongate, about two and a half times as long as 

 breadth between the pronotal angles ; head about as long as 

 breadth at base including eyes, the lateral lobes meeting in 

 front of the central lobe for about half their length and only 

 slightly divergent at their extreme apices, ocelli at base, very 

 much nearer to eyes than to each other • antennae with the 

 basal joint about extending to half the length of head, second 

 and third subequal in length, each shorter than fourth or 

 fifth, which are also subequal and more robust ; rostrum 

 reaching the anterior coxae ; pronotum about half as long as 

 greatest breadth, deflected from a more or less distinct 

 transverse line between the humeral angles, which are broadly 

 rounded and only slightly prominent, the lateral margins 

 oblique, entire, not denticulate, slightly reflexed ; scutellum
