(Species of which only the females are known to me.) 

 Onthophagus importunus, n. spec. 



Head and prothorax fuscous bronze green, with the elytra very 

 dark green, nearly black, not shining and very densely pubescent ; 

 antennae rufescent with the clava sub-fiavescent ; head very rugose, 

 genae angular at middle, clypeus rounded laterally, distinctly emar- 

 ginate at tip and with the outer margin very slightly reflexed, there 

 is a short, slightly arcuate frontal carina and a transverse one 

 truncate at both ends on the vertex at nearly the same distance from 

 the frontal carina and the base ; prothorax distinctly marginate 

 laterally and in front but not along the base which is rounded ; it 

 is covered with very closely set punctures which are very rugose in 

 front, on the sides, and in the median part, but are more round and 

 less confluent along the base ; elytra ampliato-ovate, very finely 

 geminato-sti-iate, striae punctulate at long intervals, intervals scro- 

 biculate, second, third, and fourth raised, second not broader than 

 the third, humeral callus distinct ; pygidium very closely and deeply 

 pitted and very densely pubescent ; metasternum sparsely punctate 

 but having no distinctly impressed median line ; apical spur of 

 anterior tibiae slender, nearly straight. 



Length 6 mm, ; width 3 J mm. 



Hah. Ovampoland (Humbe). 



Evidently allied to 0. cretus, and the male will probably prove to 

 have the same cephalic and thoracic armatures ; it resembles very 

 much 0. inisillas, and the sculpture of the elytra is nearly the same, 

 but not that of the prothorax. 



Onthophagus imitativus, n. spec. 



Black, opaque, very slightly pubescent ; head very rugose all over, 

 genae rounded, bulging, nearly sub-auriculate, clypeus semicircular, 

 hardly obtuse at tip and not emarginate there, no trace of carinae ; 

 prothorax ampliate laterally, moderately convex, marginate in front 

 and laterally but not distinctly along the base which is rounded ; it 

 is covered with very closely set, sub-contiguous elongate granules 

 disposed equally all over the surface, and there is a trace of a fine 

 longitudinal median smooth line in the posterior part ; elytra 

 ampliate, narrowly but very distinctly geminato-striate, striae punc- 

 tulate, intervals plane and having each two series of small, regularly 

 disposed granules, second interval slightly wider than the third, 

 humeral callus distinct ; pygidium closely granulose ; metasternum 

 deeply and sparsely punctate, median longitudinal line very distinctly
