The same month we received by request from Prof. H. A. Gossard, 
Lake City, Fla., specimens of the larva of this species found on cowpea,

is velvet}^ brown, with long metallic-green hairs on the thorax and 
contiguous parts of both pairs of wings. The fore- wings are orna-

The egg is nearly spherical, depressed below, and marked with ridges, 
converging at the polls. The eggs when first deposited are glistening 
white, but soon become yellow. They measure nearl} T a millimeter in

The larva is of the peculiar appearance shown in the illustration 
(5, c), nearly cylindrical, with narrow neck and prominent head. The
