Abstract. Prioiwderci melallica Jacoby is a new synonym of Lycaste triclioa Gistl.
The genus Lycoste Gistl is redescribed and restricted to the species L. triclioa and L.
ewnolpoides (Lefevre). The genus CullicoUispis Bechyne is resurrected for Ihc remaining
species formerly placed in Lycaste.
Key Words: Chrysomelidae. Hmnolpinae. Lycaste. Prionodera. Cidlicolaspis
