SCARAB^US SENNAARENSIS, Cast., 



Hist. Nat. d. Ins., ii., p. 66. 



" This species resembles much S. puncticollis, Latr., but it is 

 easily distinguished by being more shiny black, by the fine and very 

 closely set punctuation of the prothorax, the very sharp angles 

 of the clypeus, the yellow antennal club ; the sides of the prothorax 

 and the legs are set with long rufous hairs ; the anterior tibiae 

 have four very strong and perpendicular teeth outwardly ; the 

 pedicel of the antennae are entirely brownish red. 



Length 8 lin. ; width 4f lin. 



Hah. Sennaar." 



Mr. Marshall informs me that this species has been captured by 

 Burchell during his South African journey. 



Sub-Gen. SEBASTEOS, Westw., Cat. i., p. 57. 

 Sebasteos westwoodi, Har. Coieopt., Heft v., 1869, p. 95. 



This species is not synonymous with S. galenus, Westw., as I 

 thought. It most closely resembles the latter in general appearance, 

 but the prothorax, instead of bearing equally distant punctures, 

 bears equally distant granules covering the whole of the discoidal 

 part except a sub-arcuate space on each side of the base ; in the 

 median part there is a narrow, median, longitudinal line which 

 becomes impressed from the centre to the basal part, where it 

 culminates into a sharp carina. 



I found one example of this species among a small number of 

 S. galenus, from the same locality. 



Length ($ ) 32 mm. ; width 19 mm. 



Hah. Transvaal (Zoutpansberg). 



Gen. PACHYSOMA, Cat. i., p. 76. 

 Pachysoma rotundigena, Felsch., 



Deutsch. Entom. Zeitschr., 1907, p. 273. 



" Black; head from the front to the back equally arched, closely 

 plicate longitudinally, the anterior margin with four teeth, the two 

 central ones considerably longer than the other two, genae rounded, 

 prominent but distinguishable from the head in front only, the 

 border is finely crenated, the surface finely granulated; the pro- 

 thorax is widest behind the middle, rounded there with the sides 

 entire, the whole lateral margin is toothed, the hind angles sharp,
