copulation at 5.24 P.M., half a minute after his introduction. On 

 May 11 she was hostile to him, as also on May 13; at this date she 

 was very large with eggs, which she laid May 19. May 24 I introduced 

 c?No. 115 at 4.51 P.M., he copulated immediately; he was removed at 

 4.05, and c?No. 116 placed with her, copulating at 4.07^ and 4.08. 

 May 25 I put ind'No. 116 from 10.10 to 11.00 A.M., but he avoided her. 

 though she made amatory signals; and cJ^No. 115 behaved similarly 

 on the evening of the same day. May 27, d^No. 125 copulated at 2.50 

 and 2.53 ; and the same 6" at 8.43 and 8.45 P.M., May 28. On May 28 

 put in d^No. 128, copulation at 8.57^ and 8.58 P.M. May 29, put in 

 d^No. 125, copulations at 6.00, 6.01, 6.02 P.M.; and he copulated with 

 her on June 1, at 5.30^ and 5.31 P.M. June 2, d^No. 126 was placed 

 in her cage, but he showed no eagerness and was removed at 9.25 P.M. ; 

 then d^No. 125 was put in, and copulation followed at 9.32^. June 30, 

 put in d^No. 125, but no copulation ensued, although she was eager. 

 June 17, put ind^No. 215 at 11.00 A.M., and two copulations followed 

 within 3 minutes. (A total of 27 observed copulations.) 



(2) ? No. 16 copulated with d" No. 13 at 7.55, 7.56, 7.56+, 7.58, 8.00 

 and 8.04^ P.M., on April 29, the d^ after each copulation moving half 

 an inch away from her and drawing his palpi through his jaws. May 4 

 I introduced d^No. 19 from 7.35 to 9.40 P.M., but there was no copula- 

 tion. On May 5, d'No. 19 copulated at 8.14, 8.18 and 8.19 P.M. ; and 

 the next day at 7.39 P.M., a minute after his introduction. On May 8 

 d^No. 19 copulated with her at 5.33 and 5.37 P.M.; and on May 13 at 

 4.22 and 4.23 P.M. On May 14 I introduced d'No. 7, on May 15 d'No. 

 19, on May 16 d^No. 19, but she was hostile on each occasion (she 

 oviposited May 25). On May 25, at 10.10 A.M., just after the comple- 

 tion of the cocoon, d^No. 115 was introduced; she first rushed at him, 

 then held herself in copulating attitude, then became again hostile. 

 May 27 I introduced d'No. 127 at 3.10 P.M., she rushed at him and 

 started to enshroud him, but when he touched her with his legs she 

 ceased, and copulation followed at 3.11 and 3.12. May 28, d''No. 127 

 was put in at 9.08 P.M., copulations followed at 9.09, 9.09^, 9.10. 

 May 29, d'No. 127 copulated at 5.27 P.M. ; but when d" No. 128 was put 

 in his place at 5.30, she chased him hostilely. June 1 I put in d^No. 

 127, but she acted hostilely (perhaps from hunger this time, as she had 

 not been fed for three days). June 2 I introduced d* No. 127 while she 

 was feeding, and she chased him from the web. June 7, d^No. 182 

 was introduced, but though she signalled eagerly he did not mate. 

 June 15 (a cocoon was built by her the preceding day) I introduced 

 d^ No. 182, copulation ensued at 7.25 and 7.27 P.M. (A total of 22 

 observed copulations.)
