punctate along the margins ; it has a slightly marked medial 

 longitudinal line, and a longitudinal depression along each side 

 parallel to the margin. The front of the thorax is emarginate, 

 the base is cut straight. The elytra are oblong, widened behind ; 

 each has nine longitudinal raised lines; the interstitial spaces 

 are concave hollows, and under a strong lens they are found to 

 be very finely transversely strigose, and covered with numerous 

 scattered papillse, from each of which arises a hair. The apex 

 of the elytra is truncate, slightly sinuate towards the suture, 

 which has a tendency to project ; the under side is of the same 

 colour as the upper, with the exception of the trochanters and 

 thighs, which are ferruginous. The tips of the thighs are 

 black. The pilose pubescence on this as well as the other 

 species appears to be easily rubbed off. 



This species comes very close to G. africana, Dej., but is distin- 

 guished by the thighs and first joint of the antennae being red, 

 while in africana they are black. The thorax is also somewhat 

 more elongate. 



2. G. ffracilis, mihi. 



Nigra, pilosa, elongata; thorace elongato-cordato, fortiter ru- 



goso-punctato ; elytris sulcatis, interstitiis concavis. 

 Long. 9| lin., lat. 3 lin. 



Not to be distinguished from G. africana, Dej., except by a 

 comparative description. It is smaller and more elongate ; the 

 thorax is proportionally narrower and more elongate ; the an- 

 terior angles are less rounded, sloping forward to the head more 

 gradually; the head is more deeply punctate, and the thorax 

 more deeply rugose-punctate. The clypeus has the front and 

 anterior margins reflexed ; the centre of the front of it is raised, 

 so as to leave a fovea on each side of the anterior margin. Like 

 africana it is wholly black, with fuscous or ferruginous hairs 

 beneath the tarsi. The tarsi are more elongate than in africana. 



3. G. interstitialis, Dej. 5. 295. 



Nigra; thorace cordato; elytris sulcatis, interstitiis concavis, 



bilineatis, subtilissime transversim striatis, pilosis. 

 Long. 9^ lin., lat. 3 lin. 



Macrocheilus, Hope. 



1. M. grandis, Dej. 5. 400. 



Ater; labro subporrecto, Isevigato; elytris elongatis, sulcatis. 

 Long. 12i lin., lat. 4 lin.
