Apriona. 

 Chevrolat, Rev. et Mag.de Zool. 1852, p, 414. 

 Characteres ut in Batocera, sed antenncB in utroque sexu fere 

 aequales, laevigatse, scapo leviter cicatricoso ; elytra parallela, 

 humeris dentatis, baud spinosis ; et tibicB anticse haud den- 

 ticulatae. 

 M. Chevrolat describes the antennae as 12-jointed, which is 

 erroneous, and the eye as deltiform, which is true only with re- 

 ference to the small h, not the capital A. The genus is a very 

 natural one, having for its type A. German, Hope (^Lamia).*

 diagnosis will serve to differentiate it : —

 Characteres ut in Apriona, sed scapus \a\de cicatricosus, oculi mediocres, lobo 

 inferiori angustato, et tarsi articulo ultimo praecedentibus multo breviore.
