Sub-Family YL— BALANIXIN J^. 



The single genus which constitutes this sub-family has been 

 heretofore arranged as a tribe, in the vicinity of Anthonomini. 

 It differs, however, from that 1ril)e, as from all other Coleoptera, 

 known to us l)y the movement of the mandibles Ijcing vertical 

 instead of horizontal;* the mandibles are short, pyramidal and 

 acute, and the condyle is on the uj)per side; the teeth seen in 

 most Curculionidie are wanting; the inner edge is more eonvexly 

 curved than the outer, so that in the ordinary position, the points
