Prof. Uhler states that in Western Hayti this species occurs abundantly in the 
neglected and weedy parts of gardens, and that he also obtained a few specimens in that 
country from the Palma Christi, or castor-oil plant. He also remarks that “the most 
typical form of this species inhabits the West Indies and Mexico; those with the 
humeral angles shortest are found in Nebraska.” All the Central-American specimens 
which I have examined have the humeral angles well developed and the red thoracic 
fascia prominent.

The specimen figured is from Guatemala. Stal gives “‘ Puna” as one of the localities 
of this insect, meaning, I suppose, the island of Puna off the coast of Ecuador.
