grown katy-did, and a large brown twig-mimicking cater- 

 pillar. 



Lycosa rahida Walck. In following a suspicious-look- 

 ing hole I soon uncovered a chamber, two inches below 

 the surface of the ground ; this contained this large spider 

 with a small wasp larva attached to it which shows that 

 this spider is the prey of a digger wasp. 



Lycosa kocJii Kyserling [J. H. Emerton]. This 

 spider was found in a rubbish pile on May 15, carrying 

 her egg-case. This she lost while being transferred to 

 the vial, but she soon regained it and adjusted it as before, 

 and carried it constantly. A week later I suddenly found 

 that her body was completely covered with myriads of 

 little ones. After three days, they disbanded. The 

 mother was then very very weak and thin and walked 

 slowly, and died after two more days. 

 ' Phidippus tripv/nctata [J. H. Emerton]. These spiders* 

 nests were abundant about the sheds June 13 to 19, 1920. 

 One unique nest had two openings; when disturbed, the 

 spider would use either extremity which at the time 

 seemed the safer.
