a moderately broad, black, tornentose band placed at a short distance 

 from the suture and reaching from the base to a little short of the 

 apex where it Ivocomes acuminated, outer margins slightly albo- 

 marginate. 



A reproduction of G. bilineatus, Boh., although a little less 

 quadrate, but the suture is not white nor is there any trace of a white 

 line bordering the dorsal black bands of the elytra. Varies also in- 

 colour from earthy-brown to light-cinnamon. 



Cape Colony (Kimberley), Tiansvaal (Potchefstroom, Klerksdorp). 



Gr. EGREGIUS. 



Niger, fiavo pubcsccns, capite magno, medio late denudato ; pro- 

 thorace lato, angulis anticis valde prodactis acutisque, vitta mediana 

 a.ngusta, nigra ; elytris snb-ovalibus, sutura antice, fascia arcuata 

 communi in medio arcuque apicali nigris ornatis. 



Long. 17-18, lat. 8-9 mm . 



Black, covered with a dense yellowish pubescence. Head very 

 large, punctured with a broad denuded space in the centre ; prothorax 

 very broad, short with the anterior angles very acute, and with a 

 black narrow band in the centre ; elytra sub-ovate, densely pube- 

 scent with a black crescent-shaped dorsal patch, a small triangular one 

 at the apex of each elytron, connected by a broad sutural band which 

 does not reach the apex. 



Allied to G. ancora, Dej., but the dorsal fascia instead of being 

 straight is slanting and forms in conjunction with the suture a broad 

 crescent with the horns directed towards the base. The apical fascias 

 are shaped exactly like in G. ancora, and the median black band of 

 the prothorax is much narrower. «. 



An intermediate form between ancora and Westwoodi. In the 

 three exampies which I have examined, the pubescence of the pro- 

 thorax is of deeper yellow than that of the elytra. 



Transvaal (Rustenburg), Zambeze, ? Limpopo. 



Gr. ZAMBEZIANUS. 



Niger, pube ochracea dense vestitus^ capite protheraceque in media 

 atro-vittatis ; elytris sub-quadratis, sutura plagaque communi trian- 

 gula, parva, post medium posita nigris. 



Long. 13, lat. 6 mm . 



Shape of G. cordiger but the elytra are slightly more quadrate and 

 the colouring of the tomentum is deeper ochraceous. Head with a
