BOLBOCERAS STEECOKOSUM, U. speC. 



Female : Brick-red, with the head and the greater part of the 

 prothorax ferruginous ; labrum shghtly emarginate, clypeus truncate 

 at tip, sinuate laterally, the basal angles are not at all sharp, there is 

 no trace of any median tubercle, and the whole surface is sub- 

 scrobioulate except a small basal area, which is punctulate ; prothorax 

 moderately sinuate in front, median part of the anterior margin 

 simple, it is covered with deep, irregularly scattered pianctures which 

 are more closely set as well as scrobiculate on the sides, but along 

 the basal margin there is an impunctate, narrow, transverse zone, in 

 the centre of the anterior part there is a faint, longitudinal impression ; 

 scutellum impunctate ; elytra punctato-striate, eighth interval a little 

 shorter than the ninth, but reaching the apical part of the humeral 

 callus ; under side and legs densely pubescent ; anterior tibiae 

 six-dentate. 



Length Ih mm. ; width bh mm. 



Hah. Cape Colony (Bechuanaland). 



This species closely resembles small female examples of B. 

 2)annosuin, but the anterior tibiae are distinctly six-dentate, whereas in 

 the latter they are seven-dentate.

Plate XXXVI., tig. 26. 

 Insect Caffr., ii., p. 372. 



Ferruginous red, with the median part of the prothorax and the 

 head often infuscate ; labrum emarginate and with a very distinct 

 transverse carina running along the apical margin, head scrobiculate 

 except for a small basal area, which is smooth and vaguely punctate ; 

 clypeus short, transverse, a little sinuate below the basal angles which 

 are distinctly aculeate, while in the centre, but a little in advance of 

 them, there is a small tubercle hardly more raised than the basal 

 angles, and which in the large development is united diagonally with 

 them by a slightly raised carina ; prothorax moderately deeply 

 sinuate in front, and with the median part of the margin bi-tuberculate ; 

 it is covered with somewhat scattered, deep punctures denser along 

 the sides, and with a fairly broad basal impunctate transverse space, 

 and in the anterior part of the disk there is in both sexes a round, not 

 very deep, smooth impression reaching from the apical margin to 

 about one-third of the length ; scutellum with a few scattered 

 punctures ; elytra punctato-striate, punctures deep, very closely set, 

 eighth stria slightly shorter than the ninth, and both reaching the
