LOVE DANCES OF SALTIGRADES. 59 



Fifth, the first legs are extended directly forward, close to the ground, 

 the legs being slightly curved, with the tips turned up (Dendryphantes 

 capitans), or again he lies down on one side with the legs well extended. 

 Sixth, the fore legs are elevated high above the head and curved towards 

 each other, while the body is sustained upon the remaining feet during 

 the saltigrade movement (Philffius militaris), or again the fore legs are 

 extended and the abdomen turned up. (Habrocestum splendens.) 



Seventh, the spider maintains a ramj)ant attitude, something like the 

 position last mentioned, with the fore feet raised high and curved forward, 

 instead of toward each other. (Astia vittata.) 



These are the most characteristic positions, and they are maintained 

 during the courtship dance with more or less persistence, according to the 

 various species. The position after the consummation of the 

 Position ^vooing is much the same in all species. In mating, the male 

 ° , ^ ® usually crawls over the female, or the female crawls under the 

 Mating male, and the palps are applied to the vulva while in this atti- 

 tude. An exception was observed in two species, where the male 

 jumped upon his partner from a distance of one or two inches, the ap- 

 proach being per saltern, instead of by the gradual crawling movement 

 above indicated. 



For the most part the female appeared to be complaisant or, at the 



furthest, indifferent. She maintained herself in a position to 



ema e ^r.^^ch the antics of her lover and to be influenced by them. 



Sometimes she ran away and avoided the advances of lier suitor, 



but showed no disposition to attack or annoy him. 



At least one exception, however, to this general complaisance was ob- 

 served in the case of Phidippus rufus, who is a ferocious creature, having 

 a great advantage in size over her partner. It happened to one 

 A Fero- assiduous male that in an unguarded moment he was pounced 

 _, , uj)on and eaten up by the lady whom lie was wooing. Another 

 species of Phidippus showed the same ferocity. This is our 

 large black Phidippus morsitans, a creature not in good repute in certain 

 parts of the country, it being regarded as one of our poisonous species.^ 

 The single female which the Peckhams caught during the summer was a 

 savage monster. The two males provided for her had offered her only the 

 merest civilities when she leaped upon them and killed them. 



The male of this species has the first pair of legs much longer than the 



corresponding legs of the female, and also it is thickly adorned 



Vain \s\\X\ wliite hairs, some of which are long and others short and 



Signals scale like. It was while one of the males was waving these 



handsome legs over his head that he was seized by his mate and 



devoured. This love signal was evidently not sufficiently attractive to win 



' Vol. I., page 276. A letter just received from Prof. Peckhani denies this accusation.
