N2  - (1) a. The mating behavior (including copulation) is described for the first time in the following species: Pardosa modica, P. emertoni, P. saxatilis, P. lapidicina, Lycosa helluo, .L. gulosa, Dolomedes scriptus, Phidippus clarus, P. audax, Philodromus pernix, and Coriarachne versicolor. b. The courtship only is described for the first time in Phidippus purpuratus. c. In Lycosa rabida and Pardosa milvina new data concerning the copulation, and in Schizocosa crassipes new data concerning courtship, are added to what is already available from Montgomery's work. d. In Tibellns oblongus and Xysticus triguttatus new data are added to the accounts of Gerhardt, and of Emerton, respectively. (2) a. On the basis of a large number of observations and experiments with the males of 19 species from 4 families of vagabond spiders, it is pointed out that the senses involved in courtship may vary with the species. b. There is no evidence that a sense of smell is used in sex recognition by any spiders. At least this sense plays no part in initiating courtship activity in the male. c. There is no evidence that Attid males can "recognize" the females by any sense other than sight. At any rate, it appears that the visual stimulus is the only one that suffices to incite courtship in this family. d. In one Lycosid observed, Pardosa emertoni, the courtship behavior is elicited only when the male can both see and touch the female. e. In the Pisaurid, Dolomedes scriptus, the sole stimulus for courtship is the chemoperception by contact of an ether-soluble substance normally covering the cuticle of the female. f. In the Lycosid, Pardosa milvina, the chemoperception by contact of an ether-soluble substance normally covering the cuticle of the female, together with the simultaneous perception of tactile stimuli will elicit courtship. This probably holds for P. saxatilis, Lycosa rabida, Schizocosa crassipes, and perhaps for Pardosa modica. Moreover, the sight of a moving Lycosid of about their own size may, in some cases, be sufficient for these males to start courting. g. In the Lycosids, Pardosa banksi, and probably Lycosn gulosa and L. helluo, only the simultaneous perception of both tactile and tacto-chemical stimuli suffices. Visual stimuli play no part in eliciting courtship. h. The condition in the Thomisids is in all probability similar to that in the preceding group of Lycosids. (3) a. In the case of those species in which contact chemoperception occurs it is shown that perception is not limited to the tarsi. Such stimuli can be perceived on all the segments of the legs as well as on the abdomen. From the known distribution of the slit sense organs it is probable that they are the chemoreceptors involved in courtship.
