capable of being expanded at the will of the reptile, and is 

 extremely striking, as most species of the genus are otherwise 

 somewhat sombre in general coloration. Walking along a 

 forest path near Chimbo in Ecuador, I saw one of these lizards 

 on a tree-trunk (their favourite haunt), with its bright scarlet 

 pouch fully distended. As I was watching, a butterfly of the 

 genus Catagravima darted at the pouch, and the lizard snapped 

 at the insect but missed. This incident gave me the idea that 

 possibly one of the uses of the gular pouch is as a decoy for 

 butterflies. Many of the most handsome JVt/mphalidae, such 

 as the Catagrammas, delight in settling on tree-trunks, and 

 they are constantly chased off by other individuals, apparently 

 out of pure mischief. So that when one of these butterflies 

 sees a patch of colour on a tree-trunk, it darts at the supposed 

 intruder, and if the latter turns out to be the gular pouch of 

 an AiioUs so much the worse for the insect." 



Mr. G. A. K. Marshall congratulated Mr. Rosenberg on 

 his extremely interesting notes, and said that he had been 

 endeavouring to stimulate entomologists in the Tropics to 

 make observations on the behaviour of bix-ds, etc., towards 

 butterflies by sending copies of his paper to them. 



The President, Mr. G. 0. Champion, Mr. J. W. Tutt, Dr. 

 T. A. Chapman and other Fellows continued the discussion.
