a^. Protliorax neither truncate, retuse in front, nor ex- 

 cavate, 



Clypeus very broadly sinuate at apex ; protliorax 



with a small, median tubercle achates. 



C^ Cephalic horn laminate at base and cylindrical at tip. 

 D". Apical spur of anterior tibise bent outwardly. 



Prothoracic lobe wide, arcuate, hardly sinuate, lateral 

 cavities narrow and shallow, median part of the head 

 and median dorsal part of prothorax impunctate 

 (pi. xxxiii., fig. 10) urus. 



D^ Apical spur of anterior tibiae curved inwardly at tip. 



Clypeus deeply incised and sub-lobate at tip ; prothorax 

 scrobiculate in front and laterally, and very deeply 

 and closely punctured in the dorsal part insidiosiis. 



A\ Prothorax simple. 



B. Males without a cephalic horn. 



D, Inner part of anterior tibise nearly transverse {Litocopris) . 



Clypeus broadly emarginate at tip ; prothorax nearly 



parallel ; elytra deeply XDunctato-striate {muticus. L 



CoPEis MACEK, n. spec. 



Black, shining ; clypeus deeply incised in the centre and less 

 deeply on each side of it, the space between the two incisions 

 forming a short, slightly recurved lobe, the whole head is deeply 

 and roughly punctured, and it bears a strong, compressed, slightly 

 curved horn reaching higher than the prothoracic median lobe, with 

 an angular projection on each side behind near the base ; prothorax 

 strongly declivous, lobate in the middle, the upper median part of 

 the lobe incised in the centre, sub-dentate on each side of the 

 incision and with the outer angle strongly dentate, the anterior part 

 of this median lobe is sloping, and it is edged on each side by a 

 sharp, very conspicuous, slanting carina running from the outer tooth 

 of the upper part of the lobe to a short distance from the apical 

 margin where it ends in a sharp angle, on each side of the median 

 part there is a deep excavation reaching as far as the base of the 

 lobe, and bounded on each side by a nearly erect, compressed 

 triangular sharp tooth, there is a distinct, median, longitudinal 

 groove in the dorsal part, and the surface is covered by deep, round, 

 foveolate punctures which are not, however, closely set in the 

 anterior part of the median lobe, and leave on the dorsal part a 

 longitudinal smooth space as wide as the median lobe ; elytra a little
