The life-history of the two species found within our fauna has not as yet been carefully worked out, and aside from a knowledge of the fact that the caterpillars closely resemble in many respects the caterpillars of the two succeeding genera, being provided with branch- ing spines on their bodies, we do not know as yet enough to give any complete account of the earlv stages of these insects.

There are a few crimson marks at the base of the hind wings, and two light-colored lunules near the inner angle of the hind wings. Expanse of wing, inches. This butterfly, which mimics the genus Helicouiiis in the out- line of the wings, is very common in the tropics of America, and only appears as an occasional visitant in southern Texas.
