A small dull black hairy species, distinguished in well-developed males from 0. mexi- 

 canus and its allies by the absence of the posterior carina of the head, the anterior 

 (frontal) carina being, in compensation, rather strongly raised. The thoracic lobe is 

 never much elongated or furcate. An example from Jalapa is figured. 



19. Onthophagus iodiellus.

 bidentato, genis rotundato-sublobatis cum clypeo grosse punctatis ; thorace grosse discrete punctato, medio 

 antice carina brevi obtusa ; elytris conspicue crenato-striatis, interstitiis sparsim punctulatis, planis.
