much more strongly plicate than the male, and black, tubercle on 

 the vertex more developed ; legs normal. 



Length 19-23 mm. ; width lOi-12 mm. 



Hab. Cape Colony, apparently restricted to the South- Western 

 part. 



Onitis sphinx, Fabr., 

 Plate XXXIV., fig. 12. 



Colour, shape, and sculpture of 0. cvjgidus, but smaller, and at 

 once distinguishable in not having the base of the prothorax 

 marginate, except slightly between the two basal impressions ; the 

 metasternum is distinctly grooved longitudinally at middle. 



Male : Clypeus not emarginate in front as in 0. aygulus; anterior 

 femora with a small tooth at a short distance from the upper margin 

 of the groove and another small one opposite in the lower edge, as 

 well as a long and sharp one on the same edge, but close to the 

 knee, and a short, blunt tooth or sharp tubercle at about the median 

 part of the inferior surface ; anterior tibiae quadri-dentate outwardly, 

 not sinuate inwardly, mucro not much incurved, inferior carina not 

 thickened and with six or seven serrations, or small, even teeth ; 

 intermediate coxte and tibiae as in 0. aygulus ; trochanters of pos- 

 terior legs not spinose, lower margin of femora produced into a 

 sharp, long, sub-horizontal triangular tooth situated at about the 

 median part ; posterior tibiae simple. 



Female : The clypeus is only a little more elongate than in the 

 male, but not aculeate, and the tubercle on the vertex is very much 

 more developed. 



Length 10-21 mm. ; width 7-10^ mm. 



Very common everywhere in South Africa, except perhaps in the 

 extreme south-western part of the Colony. It occurs probably in 

 the whole of Africa, and is met with also in Southern Europe and 

 Syi'ia.

 Insect. Catirar., ii., p. 255. 



Totally testaceous, with three large, longitudinal, green metallic 

 patches on the prothorax ; clypeus elongate in both sexes, clypeal 

 and frontal carinas as in the two species preceding, but there is only 

 a faint trace of a tubercle behind the interrupted frontal carina in 

 both sexes, and the basal carina is hardly distinct even in the 

 female; prothorax a little attenuate laterally in front, l)ut nearly
