brighter yellow than the outer sides ; elytra elongato-quadrate, with 

 on each side a juxta-sutural black band reaching from the base to 

 about the median part, broadest there and attenuated diagonally 

 from its broadest part towards the base but not reaching it ; behind 

 a supra-marginal apical triangular patch on each side, on a line 

 with the inner edge of the anterior elongated patch, and sometimes 

 connected with it by a fine longitudinal sutural line ; legs black. 

 Length 13 mm. ; width 6 mm. 



Hah. Cape Colony (Kimberley, Barkly), Bechuanaland (Molopo, 

 Bawankitsi), teste Chaud., Mashunaland (Salisbury). 



Geaphipterus zambezianus, Per., 

 Trans. S. Afric. Phil. Soc, 1892, p. 99. 



Covered with a deep ochraceous pubescence ; head broadly denuded 

 in the centre ; antennae black, with the three basal joints red ; pro- 

 thorax moderately broad, with a median black band ; elytra elongato- 

 quadrate, with a broad sutural band reaching from the base to past 

 the middle, where it merges into a triangular black patch only twice 

 as broad as the sutural band, and the point of which stops a little 

 short of the apex. Length 13 mm. ; width 6 mm. 



Hah. Neighbourhood of the Zambeze River. 



Geaphipterus cordiger, Bej., 

 Spec. Col., v., p. 461. 



Covered with a yellow pubescence ; head broadly denuded on the 

 vertex ; first and second joints of antennas reddish ; prothorax mode- 

 rately broad, with a broad median black band ; elytra elongated, 

 nearly one-fourth broader at the apex than at the base, a broad black 

 sutural band merging into a more or less cordiform black patch 

 beginning at about the median part, produced behind in a triangular 

 narrow sutural band, hardly reaching the apex ; legs black. Length 

 13-15 mm. ; width 6-7 mm. 



The habitat of the typical G. cordiger seems to be the grassy plains 

 extending from the northern parts of the colony towards the west, 

 as far as Ovampoland and the Marico District (Transvaal) in the 

 east ; further east and north they are replaced by G. Wahlhergiy 

 while in Natal and the southern part of the Transvaal we meet Avith. 

 G. hamatus, the discoidal patch of which often assumes the shape of 

 that of G. cordiger, but is always more quadrate. 



Hah. Cape Colony (Calvinia, Kimberley), Orange Free State 

 (Parys, Cronstad), Transvaal (Middelburg), Upper Limpopo, Bamara- 

 land, Bechuanaland, Ovampoland. 



The median patch on the elytra varies in size ; the anterior edge
