[December 
At the June meeting, Miss E. P. Butler described the de- 
velopment of pseudopodia on the first abdominal segment of 
several insects. These at first resemble the rudimentary legs 
but at an early stage their growth stops, they become enveloped 
by the growing parts around them and are eventually absorbed. 
Prof. W. M. Wheeler gave an account of a recent visit to the 
Panama Canal Zone and the Galapagos Islands, referring es- 
pecially to the large associations of insects that live in the 
hollow stems of various tropical trees.
