Southern Masai Country, near Ugogo (Dr. Baxter), 

 Differs from the two previously described species by many 

 characters, the chief of which is the narrow clypeal horn, gradually 

 and slightly dilated towards its apex, where it is sinuate-truncate, 

 instead of bifurcate. The chalky tomentose markings of the elytra 

 are arranged in longitudinal stripes, the marginal one being the 

 broadest, and continuing round the apex to the narrower sutural vitta, 

 two other shorter discoidal vitta? being partly dilacerated. There is 

 also a large basal spot on each elytron.

 Mamboia (Mr. Last). 



This very remarkable species does not fall into any of the 

 numerous sub-genera into which the genus Ceratorhina has been 

 divided, a new generic name {Doedycorhina, in allusion to the scoop- 

 formed nasal horn) is, therefore, proposed for it. The long, rather 

 narrow and bowed anterior tibiae are unlike those of any other species 

 of the group, but they somewhat resemble the form shown in 

 Ischnoscelis Dolirni, Westw. In the velvety surface and markings, 

 the species resembles the ChordodercB. The tawny-red spots of the 

 elytra are, on each, 10 — 12 in number, extremely irregular in size and 

 arranged longitudinally, those near the suture tending to form short 

 fasciae.
