the median part of the disk is more minutely but as roughly punctate 

 as the sides, but there is a smooth band along the median part of 

 the base, and the median anterior part is shiny and a little punctate. 



My female example is much smaller than the $ (11mm. x 7 mm.), 

 and lighter red. Both examples at my disposal ( $ ? ) seem to be of a 

 greater development than those on which Kolbe founded the species, 

 but they come from the same locality (Okahandja in Damaraland), 

 and I have no doubt that they are the same species. 



Length 11-14^ mm., width 7-9f mm. 



This species is, like B. capicola, easily distinguished from all its 

 South African congeners by the shape of the thorax. It should 

 precede B. damarinum, and it belongs to the same group. 



Hab. Damaraland (Okahandja). 



BOLBOCERAS FAUSTUM, n.Sp. 



Male and Female : Fuscous brick-red with the anterior part of the 

 prothorax darker than the sides or the elytra, glabrous above, shiny, 

 clothed with a dense fulvous pubescence underneath ; antennae 

 flavescent ; labrum emarginate in the centre, above the labrum is a 

 sharp, transverse ridge reaching from side to side, not aculeate at the 

 ends, and on the centre of the frontal part rises a high, compressed, 

 sub-laminate tubercle truncate at the tip, the frontal part is 

 trapezoid, being about one-third wider at the base than across the 

 clypeal part the outer margin of which, close to the genae, is highly 

 reflexed, the surface is very deeply and very closely punctate, the 

 sub-foveate punctures are almost contiguous, especially in front, and 

 separated by a narrow wall ; prothorax with an anterior, sub- 

 quadrate, sloping depression, rather than an excavation, not wider 

 than the head and not reaching quite to half the length, this 

 depression has on each side a small tubercle, and in the upper part 

 two, somewhat short, sub-triangular ones nearly connected at their 

 base and set close to each other, the posterior part is very convex, 

 and has a shallow median longitudinal sulcus, the surface is covered 

 with sub-foveate punctures more closely set in the anterior de- 

 pression than on the sides where the intervals bear distinct aciculate 

 punctures, but these punctures disappear above the median part of 

 the base for about one quarter of the whole length, except in the 

 sulcus which is plainly punctate; scutellum closely but very weakly 

 aciculate ; elytra longer than the prothorax, punctate striate with 

 the punctures deep, intervals plane, smooth ; femora almost im- 

 punctate ; anterior tibiae 5-dentate outwardly. 



Length 11-16 mm. ; width 7i-10 mm.
