Femina a mari (ut supra scriptus) difFert capitis et pronoti

 bifidum erecta; pronoto antice retuso, area retusa minus nitida

This is the only species known to me, of those having the hind 

 tibise transversely multicarinate, in which the 14th and 15th 

 elytral striae do not coalesce; although they are contiguous near 

 their front extremity they are (even at that part) distinctly two 

 rows of punctures; in the other species of the group these striae 

 coalesce at the corresponding point and are there a single row of 

 punctures. The male resembles that of rhinoceros, Macl., more 

 closely than any other male known to me. It differs from rhino- 

 ceros, in respect of its head, by the frons being much less vertical; 

 and, in respect of its pronotum, by the horns much wider (viewed 

 from the side) and placed with their broad faces much less parallel 

 to the centre line of the body, so that when viewed from behind 

 .the bifidity of both horns is visible, whereas when rhhioceros is 

 viewed from behind the bifidity of the horns is not apparent; 

 also, in respect of its pronotum, by the anterior excavation 

 longitudinally (not convex but) concave between the horns, and 

 by the same excavation not crossed in its middle part by a
