examples, the sub-median excavation is usually very shallow or hardly 

 noticeable except in the great development, and the distinctive dif- 

 ference, apart from that in size, is to be found in the much more 

 deeply and more closely punctured prothorax. 



The South African examples of this widely spread species are usually 

 smaller than the Abyssinian ones. 



In the dorsal view given in plate xxxiii., fig. 9, the edge of the 

 declivous part should be three-dentate in the centre and uni-dentate 

 laterally ; the lateral view is correct.

CoPEis CASSius, n. spec, 

 Plate XXXIX., fig. 36. 



Male : Black or piceous red, shining, antennae ferruginous, club 

 flavous ; clypeus slightly emarginate at middle, nearly granular, like 

 the gense and the greater part of the head which has in the middle 

 a short, sub-conical tooth; in some examples the immediate surround- 

 ing of the cephalic tooth is smooth, but not in others ; prothorax 

 declivous in front, but not vertical ; the declivous part is not 

 broad, and has a slightly sinuate median ridge feebly carinate and 

 slightly aciculate on each side, and next to it a sub-lateral impression, 

 while in the minor development the anterior part is very slightly or 

 not at all declivous and quite simple, the anterior part and also the 

 sides are scabrose, and the latter also scrobiculate, but the median 

 dorsal part is covered v/ith closely set, deep punctures, and there is 

 a well-defined median longitudinal impressed line reaching from the 

 base to the median part, the posterior part of the disk has a sub- 

 gibbose appearance owing to the non-lobate, not quite abruptly 

 declivous anterior part ; elytra convex, distinctly punctato-striate, 

 intervals slightly convex, vaguely aciculate ; apical spur of anterior 

 tibiae bent outwardly; upper edge of valves of penis with four hamate 

 teeth on each side. 



Female : Colour of the male ; the whole head is covered with 

 scabrose punctures, the anterior edge of the clypeus is somewhat 

 plicate, and there is in the middle a short, arcuate ridge a little 

 angular in the centre ; the prothorax is more scabrose than in the 

 male and simple, the impressed line in the posterior part of the disk 

 is very well defined, and the punctate dorsal part is much narrower 

 than in the male 



Length 12-14 mm. ; width 7-8 mm.
