The peculiar part of the above cocooning, in comparison with 

 other Lycosids, was its slowness, pauses occupying more time than 

 the spinning itself. 



The number of cocoons, and the dates, were as follows for ? No. 186: 

 June 21, this one did not hatch, but was chewed up by the mother; 

 July 13, this also did not hatch. 



Care of the Young. — The cocoon is normally carried attached to 

 the spinnerets until it hatches. ? No. 317, who was captured with 

 a cocoon, bit it nearly in two around the ecjuator to allow the young 

 to escape; the young took above four hours on July 15 in leaving the 

 cut cocoon to get upon her body, and the first of them left her on the 

 night of July 19. 

 Lycosa scutulata Hentz. 



Individuals observed, males: No. 232, captured June 22, moulted July 11, killed 

 by ^ No. 273, August 21 ; Xo. 233, captured June 22, moulted July 2 and IS, 

 killed by 9 No. 271, August 25; No. 275, captured June 27, moulted July 14, 

 killed by ? No. 273, August 25. 



Individuals observed, females: Xo. 271, captured June 27, moulted July 1 and 

 20, still living; No. 273, captured June 27, moulted July 3, 14, 31, still living; 

 No. 278, captured July 2, moulted July 3, died July 24 (then immature) ; No. 

 326, captured July 23, moulted July 24, still living. 



Moult. — 9 No. 273 was found at the conclusion of the process 

 at 10.30 P.M. The exuvia was upside down and attached by its 

 feet to web-lines in the upper part of the cage; the spider was hanging 

 attached to it b}'' her spinnerets. She did not start moving until 

 10.42; at 10.57 she walked away from the old skin, and then remained 

 c^uiet for half an hour more. The old skin breaks by a horizontal 

 split, as in other spiders. 



Mating. — The following cases were seen : 



(1) 9 No. 273. After her penultimate but before her final moult 

 cJ* No. 232 was introduced in her cage on July 15, 16 and 18. 

 Though he was still immature he courted her on all these occa- 

 sions ; and he courted her at frequent intervals when they were 

 not together in one cage, recognizing her at a distance of several 

 inches through the glass of the cages. When courting he held his 

 body close to the ground, his last three pairs of legs stretched out 

 nearly straight, but his first pair of legs were flexed at the femoro- 

 patellar joint so that the femora were drawn back over his cephalo- 

 thorax, the tibia and tarsus held nearly horizontally in the air. Then 

 first, the palpi are swung outward and upward in alternation, each 

 five or six times; second, one leg of the first pair is pushed forward 

 and its foot tapped 6-10 times upon the floor in front of him, being
