undetermined where to alight. I have found no difference between the sexes as to external appearance.
The plant on which I have figured a male is found in Louisiana, growing along the skirts of woods and by fences. It is called the Spanish Mulberry. It is a herbaceous perennial plant, attaining a height of from four to eight feet. The fruits are eaten by children, but are insipid.
