one of the larger boxes, and the next day we put a male in with
her. He saw her as she stood perfectly still, twelve inches away;
the glance seemed to excite him, and he at once moved toward her;
when some four inches from her he stood still, and then began the
most remarkable performances that an amorous male could offer to
an admiring female. She eyed him eagerly, changing her position
from time to time so that he might be always in view. He, raising
his whole body on one side by straightening out the legs, and
lowering it on the other by folding the first two pairs of legs
up and under, leaned so far over as to be in danger of losing his
balance, which he only maintained by sliding rapidly toward the
lowered side. The palpus, too, on this side was turned back to
correspond to the direction of the legs nearest it. He moved in a
semicircle for about two inches, and then instantly reversed the
position of the legs and circled in the opposite direction,
gradually approaching nearer and nearer to the female. Now she
dashes toward him, while he, raising his first pair of legs,
extends them upward and forward as if to hold her off, but withal
slowly retreats. Again and again he circles from side to side,
she gazing toward him in a softer mood, evidently admiring the
grace of his antics. This is repeated until we have counted one
hundred and eleven circles made by the ardent little male. Now he
approaches nearer and nearer, and when almost within reach whirls
madly around and around her, she joining and whirling with him in
a giddy maze. Again he falls back and resumes his semicircular
motions, with his body tilted over; she, all excitement, lowers
her head and raises her body so that it is almost vertical; both
draw nearer; she moves slowly under him, he crawling over her
head, and the mating is accomplished."
