25. G. simulator, spec. nov. 



Niger, pube flavescente tectus ; capite in medio vittato ; prothorace 

 brevi, cordiformi, in medio haud vittato, albo-marginato ; elytris sub- 

 quadratis, albo marginatis, vitta lata, nigra prope suturam posita, 

 apicem attingente, postice haud acuminata vittisque discoidalibus duabus 

 albis in singulo ornatis. 



Long. 12. Lat. 5-o£ mm * 



Allied to G. bi-vittis, Chaud., but the elytra are more quadrate, and 

 the pre-sutural black band on each elytron reaches from the base to 

 the apical margin and is not acuminated posteriorly, the two white 

 doTsal bands are much more defined, the one edging the black vitta is 

 the largest of the two. 



26. G. bilineatus. Boh. 



Recorded from Damaraland, and the vicinity of Lake N'Gami. 



27. G. amicus, spec. nov. 



Niger, pube griseo- flavescente vestitus ; prothorace brevi, lato,. 

 albido-marginato, in medio nigro-vittato ; elytris brevibus, latis, sub- 

 rectis, albo-mai ginatis, vittis duabus nigris duabusque albis alter- 

 nantibus in singulo ornatis. 



Long. 10. Lat. 5 mm * 



Allied to G. bilineatus. Bohem. The shape is the same, although 

 smaller, but the markings of the elytra differ. Head and prothorax 

 with a black central vitta, the latter is short and broad ; elytra with 

 a broad black band placed at a short distance from the suture, reaching 

 from base to apex, and also a narrower discoidal one (which is often 

 dark-brown instead of black) ; between the pre-sutural band and the 

 discoidal one runs a white band as broad as the latter, which is also 

 edged on the marginal side with a very fine white line ; outer margins 

 white. 



I have seen an example where the large pre-sutural band is divided 

 in two by a very fine white line, the same thing occurs occasionally in 

 G. bilineatus. 



28. G. l^tus. spec. nov. 



Niger, capite prothoraceque in medio flavo-pubescentibus, hoc albido- 

 marginato ; elytris ob-ovatis, depressis, pube nigro-brunnea tectis y
