This species differs from Hulst's definition of Melitara in that 
the 9 antennae are without pectinations. It is also longer and 
narrower winged than the other species of Melitara. This has 
caused the female to be twice redescribed under other genera, 
as I have noted. The larva feeds in the giant cactus (Cereus 
giganteus] as described by Mr. Schwarz.
