8 M. L. Peringuey 's Third Contribution [March 30, 



whitish hairs and with a triangular black band in the centre ; prothorax 

 twice as broad as the head with the outer sides strongly ampliated in 

 the middle, covered with an ochraceous tomentum and having a broad 

 median black band and the outer margins whitish ; elytra nearly 

 rounded, plane, three times the length of the prothorax and nearly 

 twice as broad, with a very broad, black, sutural band acuminated 

 towards the apex and three narrow whitish bands on each elytron ; the 

 first two are connected at the apex with the outer margin which is 

 broadly white, and the third one stops short of it ; the 2nd and 3rd 

 interstice instead of being ochraceous like the first are dark brown. 



Probably allied to G. laticollis, Harold, which I know from descrip-

16. G. amabilis. Bohem. 



Recorded from the Lake N' Garni, and between Zambeze and

 Recorded from Lake N'Gami.

Upper side yellowish, pubescent, turning in some examples to a 

 cinnamon hue ; both sides of the head pubescent ; prothorax briefly 

 cordiform with a broad, black, median vitta, lateral sides white ; elytra 

 elongated, very little ampliated in the middle, in fact almost 

 sub-parallel, with a broad, sutural, blackish, brown band and two 

 narrow whitish ones on each elytron, the first one edges the black 

 sutural band, and the other is discoidal ; the outer margin is white, 

 and broader than the dorsal vittae. 



Allied to G. suturiger, Chaud, and shaped like it, but differs in
