250 THROUGH THE BRAZILIAN WILDERNESS 



we judged it to be a larval form, but we were none of us 

 entomologists — bore a resemblance to a partially curled 

 dry leaf which was fairly startling. The tail exactly re- 

 sembled the stem or continuation of the midrib of the 

 dead leaf. The flattened body was curled up at the sides, 

 and veined and colored precisely like the leaf. The head, 

 colored like the leaf, projected in front. 



We were still in the Brazilian highlands. The forest

At this camp the carregadores ants completely devoured
