these so-called species will be found and that the three will be again 

 united at most as local races. 



L. P. 



Sub-gen. PEOAGODEEUS, Lamb. 

 Not. Leyd. Mus., v., 1883, p. 14. 

 Onthophagus (Proagoderus) gibbiramus, d'Orb. 

 0. rarus, Klug, Pering. nee Guer.-Menev., Cat. i., p. 250. 



According to d'Orbigny, both Klug and I were mistaken in the 

 identity of this species. 0. rarus, Guer.-Menev., is confined to 

 Senegambia and the Guinea coast. 



Onthophagus (Proagoderus) plato, Bat., Cat. i., p. 251. 

 d'Orbigny, Ann. Mus. Genov., xli., 1904, p. 327. 



Judging from the description and also the habitat of this species, 

 I placed it in synonymy with 0. furcifer, Boh. d'Orbigny, however, 

 who has been able to compare the type, a single $ example, with 

 0. furcifer, as identified by me, says (Ann. Mus. Genov., xli., 1906, 

 p. 327) that plato differs from furcifer in having the upper part of 

 the body opaque instead of slightly shiny, the granules of the pro- 

 thorax are much finer, the base is more angular in the centre, the 

 apex being almost sharp instead of not plainly rounded. In the great 

 development of the $ plato differs from furcifer by the shorter, 

 almost tuberculiform frontal ridge, the vertex bears a carina slightly 

 dentate in the centre, and on each side, below the eyes, the horns 

 emit a ramus in the inner side towards the anterior third part, 

 instead of having in the middle a non-dentate ridge emitting a long 

 ramus on each side below the eyes, and the horns being simple ; on 

 the prothorax the anterior depression is little pronounced and as 

 densely granular as the rest of the superficies instead of being deep 

 and little densely punctate ; the two discoidal tubercles are much 

 weaker and situated somewhat further back, and the longitudinal 

 median furrow extends over the whole length instead of the 

 posterior half. 



Hab. Damaraland. 



Onthophagus (Proagod.) nasidens, d'Orbign. 

 Ann. Soc. Ent. Fr., lxxiv., 1905, p. 510. 



"Little shiny, sub-aeneous black, very briefly pubescent on the 

 upper side. In the female the head is sub-strongly, closely granulate, 

 the clypeus is produced in the middle into a tooth, the frontal part
