Excerpt from Additional Observations on Sexual Selection in Spiders of the Family Attidæ: With Some Remarks on Mr. Wallace's Theory of Sexual Ornamentation

On seeing the female, which he does when eight or ten inches away, he approaches her slowly; when within three or four inches lie-begins to sway from side to side by bending all the legs on'on'e side and extending the opposite ones, and then reversing the process, at the same time advancing. The palpi are stretched out sideways, thus exposing the blue clypeus. As he moves, the female eyes him attentively and seems to be interested in his display. When quite near her he raises the first legs and holds them perpendicularly upward, and then, as he comes closer, lowers them so as to touch her. This seems to frighten her, and she runs Off. The whole performance is repeated six or eight times before she finally yields, either to his boldness and persistence, as Mr. Wallace would haveit, or to the combination of these qualities with grace and beauty.
