the head more produced behind the eyes than in Larrada. Thorax: the prothorax subtuberculate at the sides; wings subhyaline and iridescent, the nervures fuscous, the tegul? pale testaceous behind. The apical margin of the first segment of the abdomen rufo-fuscous.

The insects belonging to the genus Morphota differ from those of Larrada in having three distinct ocelli, the vertex without any depressions, and the head much less compressed than in Larrada; the recurrent nervures are received nearer to the base and apex of the second submarginal cell; the species have, in fact, a distinct habit, and do not assimilate with the species of Larrada.
