black band (denuded) in the centre, antennas black with the three 

 basal articulations red ; pro-thorax cordiforrn, with a broad black 

 median band, the sides of the disk and very tomentose ; elytra 

 with a broad black 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 ; the point of the triangular patch stops a 

 little short of the apex. 



Easily differentiated from G. cordiger, Dej., and G. hamatus, Boh. 

 by the shape and size of the dorsal black patch of the elytra. 



Captured by Mr. F. C. Selous, near the Zambeze River. 



G. FRATERNUS. 



Niger, supra ochraceo-pubesce?is, antennarum basi pedibusque rufis ; 

 capite prothoraceque in medio vittatis ; elytris quadratis, vitta dorsali 

 nigra, lata, ad basim incisa alter aque angustiore prope marginem 

 posita in singulo ornatis. 



Long. 13, lat. 6 mm . 



Black, covered on the upper part with an ochraceous pubescence, 

 the three basal joints of the antennas, the tibias and sometimes the 

 femora, dull-red ; head and prothorax with a black band in the centre, 

 the latter short, broad ; elytra quadrate, with a broad, black, dorsal 

 band reaching from base to apex, but divided in two near the base by 

 a, narrow ochraceous line, and with another narrow band placed 

 between the first and the outer margin. 



The shape and colouring are those of G. plagiatus, Boh., but 

 whereas in plagiatus there is only one dorsal band on each side of the 

 -elytra incised at the base as in the present species, but broader, there 

 are two distinct ones in fraternus.
