Cataclysta Robinsonii Grote. ♂ ♀ I refer this species to Lederer's Section C.: veins 8 and 5 of the secondaries present. primaries bright golden brown. The median whitish grey space is tolerably narrow and well defined; inwardly bounded by the outwardly arcuate white transverse anterior line; outwardly by the white transverse posterior line which is angulated on the m. nervuies. Both the lines are a little uneven. From the distinct ans regularly arcuate white transverse posterior line to the base of the wing, the surface is entirely golden brown.
