I venture to take this opportunity of describing a new genus 

 as follows : — 



Taukonthophagus, mihi. 



This genus is distinguished by having the head furnished 

 with two very long branching horns, extending from the centre 

 of the head over and beyond the posterior margin of the thorax, 

 and with a small rounded dilation towards the extreme apex, and 

 a small tooth pointing inwards near the base. The humeral 

 prominences are produced into a distinct dilated strong tooth, 

 the apex slightly leaning towards the suture. The posterior 

 margin of the thorax is very strongly emarginated, the centre 

 being produced into a slight scutellary projection, which overlaps 

 the scutellary space. Abdomen is compressed towards apex, and 

 rather convex. Pygidium thickly covered with hairs.
