Genus Meganostoma Reakirt (the Dog-face Butterflies)
Closely resembling the insects of the next genus, from which they may be distinguished by the more pointed fore wings, and the fact that the rude outlines of the head of a dog are shown in yellow silhouette upon the fore wings. There are two species in our territory, one of which, M. eurydice Boisduval, found in California, may be distinguished from the other by the splendid purplish iridescence of the fore wings of the male.
