South African Coleopterous Fauna, 223 



declivity ; the elytra are occasionally testaceous, irregularly tessellated 

 with bronze, autennal club flavescent ; clypeus produced diagonally 

 laterally, deeply and broadly emarginate in front, with the angles of 

 the emargination distinct, but not sharply reflexed, the first clypeal 

 carina is triangular, sharply raised, and the median longitudinal keel 

 is very short and does not connect the first clypeal one with the 

 highly raised, sub-arcuate second clypeal carina which overhangs 

 slightly the clypeus, and reaches on each side the inner angle of the 

 genao the anterior margin of which is also carinate, but not as highly, 

 and along the base of the frontal part there is an interrupted slightly 

 raised line with occasionally a minute tubercle in the centre above 

 it ; prothorax declivous in front in the male, not carinate above the 

 declivity but having on each side of it a depression edged by a short, 

 transverse ridge set above the shiny space, it is not much ampliated 

 laterally, although it is broader than long, the hind angles are rounded, 

 the basal margin has no fold, it is covered in the median discoidal 

 part by deep, round punctures, the slightly raised intervals of which 

 are very narrow, these punctures are slightly wider on the sides than 

 on the disk ; elytra longer than the prothorax and about equally 

 broad, plainly striate with the intervals nearly plane and filled with 

 closely set granules ; pygidium nearly as broad as long, deeply and 

 closely punctate, the intervals separating the punctures forming a 

 sort of reticulation near the basal part ; metasternurn very closely 

 punctate ; inner spur of anterior tibiae nearly straight. 



This species differs from M. apicalis, Fahr., chiefly by the more 

 highly raised and retuse prothorax. 



Length 6-7 mm. ; width 4-4^ mm.

Mons. d'Orbigny (Annal. Soc. Ent. France, 1902, p. 20) does not 

 consider that the genus Miliclius should be retained, even as a sub- 

 genus, although admitting that the two species then known should 

 form a small group of the Onthophayus, near Caccobins. I cannot 

 agree with him, however reluctantly, because the presence of a cly- 

 peal carina running parallel to the margin in addition to the normal 

 clypeal keel, a character unknown in the endless number of species 

 of the genus Ontliopliagus, is certainly more important than the fact 

 of the anterior tibiae being truncate at the apex, turning an Ontliopliayus 

 into a Caccobins, or if the body is entirely glabrous into a Cacconcmus, 

 &c. The presence of additional clypeal carinae has proved of great 

 value in the classification of the Sericince and Nclolonthina, and has, 

 according to my views, too much importance not to be taken into 

 account,
