This document describes the biological cycle of two species of the genus Corades Doubleday, C. chelonis Hewitson and C. dymantis Thieme. The morphological characteristics of the two species are compared to each other, to other species of Corades and to other members of the subtribe Pronophilina. An outstanding character of the larvae of C. chelonis is the united cephalic horns which differ from the other species of Corades. The hostplant of both species is Chusquea serrulata.
