I have collected the following Lepidoptera in the country about Demopolis, Ala., lying at the junction of the Tombigbee and Black Warrior Rivers. It has been my aim to make as complete a collection as possible of the insects inhabiting this district, in which my residence has been lately fixed, but the time at my disposal for the purpose has ben cruelly limited by other duties. The summer heats preclude much exertion during the best part of the day.

All of my specimens have a very pronounccd though rather short white dorso-basal streak, which is sometimes continuous with a longitudinal median white streak upon the thorax, and in all of them the median basal streak is continuous with a white line across the anterior margin of the thorax, which is extended backwards over the tegulae. The dorso-basal streak and the markings of the thorax and tegulae are not mentioned by Dr. Clemens.

I write no less to elicit information, than to offer such as my limited material affords. In a very interesting and origional paper on Asymmetry, published by the Boston Soc. Nat. Hist. 1869-71, Messrs. Scudder and Burgess describe and figure the genital armor of all our species of Nisoniades, making seventeen species, of which nine are new. Their Virgilius I have not, and doubt its validity, my specimens of Horatiushaving a mixture of the characters of the two species; the specimens differ somewhat from each other in armor, and, what is puzzling, are very different in size, though wonderfully alike colouring, and very unlike all our northern species in one respect to be mentioned.
