when he quickly turned and faced her and she became again motionless 

 with her legs flexed closely. At 2.06 he pulled her toward and beneath 

 liim, his head facing her spinnerets and just above the pedicel of her 

 abdomen; at 2.08 turned her partially on her side, then applied his 

 left palpus from 2.08 until about 5.00, then applied his right palpus 

 on her other side from 5.00 until 9.40; the number of insertions of 

 each palpus was not noted. At 9.40 he stood over her. At 9.46 she 

 moved slightly for the first time, when he embraced her again and 

 tapped her abdomen rapidly with his fore-legs, got her agaui into 

 copulatory attitude and inserted his left palpus from 9.502- to 9.54. 

 He then withdrew this palpus and cleaned it vigorously with his 

 chelicera until 9.58, when he left her. She quickly rose and followed 

 him, but he escaped. 



(2) ? No. 243. d^No. 303 was dropped upon her web on August 19, 

 at 3.14 P.M. At 3.34 he placed his first pair of legs upon hers, while 

 he was higher in the web than she. At 3.37 she turned away, then 

 faced him again, and at 3.40 he moved still nearer. At 3.46 he sud- 

 denly grasped her with his legs, and, she flexing her legs to her sides 

 and becoming motionless, he carried her an inch away from the place. 

 At 3.49 he left her still lying inert and walked about, evidently seeking 

 a place on the web favorable for copulation, returning to and standing 

 over her half a minute later. At 3.51^ he seized two of her legs with 

 his chelicera, carried her about, then dropped her. At 3.54 she turned 

 around. At 3.59 he seized her again, placing himself over her with 

 his head directed obliquely toward her spinnerets, she lying partially 

 on one side with her legs flexed, and commenced the copulation with 

 his left palpus. The length of time of each insertion of this palpus 

 was as foUows: 3.59-4.19^, 4.20-4.30, 4.31-4.37^, 4.39-4.46^ 4.47- 

 4.56, 4.57-5.03, 5.03f-5.08i, 5.09-5.14, 5.15-5.22, 5.23-5.31, 5.31f- 

 5.4H, 5.42^-5.49^, 5.50-5.55, 5.56-6.01, 6.01|-6.09, 6.09J-6.14, 

 6.141-6.24, 6.24^6.28, 6.29-6.36, 6.36^-6.56^, 6.57-7.10^ 7.11-7.21, 

 7.22-7.30i, 7.31-7.40i, 7.41^-7.50^, 7.51-7.58^, 7.591-8.06^, 8.07-8.16, 

 8.17-8.36^, 8.38-8.39, 8.40-8.54. He inserted the palpus each time 

 by extending it downward along the left side of her abdomen to her 

 epigynum, and inserting the spirally wound process of the palpal organ 

 for its whole length; when inserted, a large sac connected with the 

 ventro-median side of the palpal organ swelled up. The palpus was 

 withdrawn after this sac had collapsed, and the palpal organ drawn 

 through the chehcera before the next insertion. At 8.55 the male 

 changed his position upon her, so as to bring his long axis parallel 

 to hers, lifted her 1 cm. backward, then stood quietly over her. At
