The genus Orochirus is closely allied to Apithes and Orocharis, the tambourine of the 

 male elytra belonging to the same type and the anterior tibiae having a large tympanum 

 on their inner side. It differs from these genera, however, in the following 

 characters :— the surface of the head, pronotum, and legs is somewhat wrinkled and 

 strongly pubescent (not even and shiny, as in Apithes and Orocharis). The apex of 

 the vertex is more elongate. The ocelli are placed in a triangle, not in a transverse
