Gkaphipterus frontalis, Boliem., 

 Insect. Caffr., i., p. 86. 



Black, thickly covered with dark ochraceous hairs ; antennae, 

 palpi, and legs entirely black ; head with two lateral bands of 

 whitish hairs uniting above the epistoma ; prothorax proportionally 

 broader than in G. cicindeloides and G. limbatus, and wdth the anterior 

 angles projecting more on each side of the head, narrowly marginate 

 with white, the lateral margin smooth ; elytra more elongate than in 

 G. cicindeloides, that is to say the humeral angles are more sloping, 

 and the median part is not rounded, they are not much broader at 

 the base than the prothorax at its widest part, broadly although not 

 deeply striate, and have a lateral narrow white band ; abdomen 

 black, glabrous. Length 13 mm. ; width 5 mm. 



In Boheman's type the hairs of the lateral bands of the head are 

 rubbed off, and only the apical patch left, hence the name of G. 

 frontalis. Although the description resembles very much that of the 

 two preceding species, the general facies is different, owing to the 

 greater width of the prothorax and the less ovate shape of the elytra. 



Hccb. Transvaal (Potchef stroom) . 



Geaphiptebus agilis. Per., 

 Trans. S. Afric. Phil. Soc, vol. vi., 1892, p. 10. 



Antennae and legs black ; head with two narrow lateral yellowish 

 bands joining above the epistoma ; prothorax longer than broad, very 

 cordiform, and of the shape of that of G. cicindeloides, covered with 

 pale yellow hairs, leaving a narrow median denuded band ; elytra 

 hardly broader at the base than the prothorax, with no humeral 

 angles, gradually ampliated from the base to near the apex, non- 

 striate, with the suture, a dorsal narrow white line, and the outer 

 margin white, a narrow and black band reaching from base to apex 

 placed between the suture and the dorsal white line, the broad 

 interval between the dorsal white line and the outer margin is 

 light cinnamon ; sides of pectus and abdomen with dense white 

 hairs. Length 12-13 mm. ; width 5|— 6 mm. 



Hab. Damaraland. 



Gkaphipterus angustus, Per., 

 Trans. S. Afric. Phil. Soc, 1888, p. 80. 

 Head moderately broad, with two lateral yellow bands joining 

 above the epistoma ; antennae and legs black ; prothorax short, a 

 little broader than the head, cordiform, but depressed instead of 

 being convex as in G. cicindeloides and G. agilis, and also broader 

 at the base, covered with light ochraceous hairs hardly whitening on
