Abstract
Having brought my studies of the neuration of the diurnals to a preliminary close, I wish to place on record here the conclusions to which they have led. The diphylism is founded on the following characters:A.–Butterflies having a short third anal vein on fore wings, curving downwardly from base to internal margin, and with only one anal vein on hind wings ......... Papilionides.B.–Butterflies having a fork to the second anal vein of fore wings at base, sometimes incomplete, often disappearing through absorption, and with at least two anal veins on hind wings ......... Hesperiades.
