Long. 5lin. ¢ Q. 
Hab. Nicaragua, Chontales (Belt); Panama, Bugaba (Champion).

more strongly clavated scape and the flexuous third antennal joint, as well as by the 
much shorter humeral carina; there is the rudiment of an elongated carina, but it is 
not sharp and polished as in Plerodia. From very small and unusually narrow indi- 
viduals of Hypsioma picticornis, to which species it is very closely allied, it differs again in
