ant-cow larvae transform into little dark 

 like excrescences, feeding on the juice of 

 the flower stems, and then the ants no 

 longer attend them. "At this late period in 

 their life history, the full-grown ant-cows 

 have gained jumping powers which they 

 are quick to exercise when disturbed. Two 

 stages of the larvse and one of the humped- 

 back adults, greatly magnified, are depicted 

 in the illustration. 



Peeping up almost everywhere, the small

 blossoms. 



On a previous visit to the meadow in 

 May, I noticed a small open space on the 

 ground about eight feet across, which was

In the meadow one may find that the 

 rain has replenished the water in the small 

 copse. At the margin, set off by a sur-
