Explanation of Plates IV and V. 



All the drawings are freehand outline sketches, and as such do not claim to be 

 accurate in all dimensional proportions, though the attitudes are true to 

 nature ami all are studies from life. The degree of magnifi- 

 cation varies in the different figures. 



Plate IV, Fig. 1. — Lateral view of a female Ocyaleundata, hanging in her web 

 and holding her cocoon. 



Fig. 2. — Copulation of Theridium tepidariorum , lateral view at the instant 

 when the male seizes the female. 



Fig. 3.— Copulation of Pholcus phalangioides, only the proximal portions of 

 the legs shown. 



Fig. 4. — Copulation of Agalena noivia, the female below and partially upon 

 her side, the male's left palpus applied to the epigynum. 



Fig. 5. — Copulation of Acrosonia gracile, the male with his left palpus ap- 

 plied to the epigynum ; the male is drawn proportionately some- 

 what too large. 



Pl.\te V, Fig. 6. — Copulation of Dictyna volupis, the left palpus of the male 

 inserted; the third leg of the male and the posterior end of the 

 abdomen of the female are supported by the web. 



Fig. 7. — Copulation of Xysticus stomachosus. 



Fig. 8. — Copulation of Pardosa nigropalpis, lateral view, the male with his 

 left palpus inserted. 



Fig. 9. — A female Pardosa nigropalpis holding her cocoon beneath her 

 cephalothorax; this is the attitude when she finishes spinning the 

 cover of the cocoon, and when she bites it open to free the young. 



Fig. 10. — Copulation of Lycosa stonei, dorsal view, the male inserting his 

 right palpus, the cephalothorax of the female hidden by the male.
