THE GENUS CALOSOMA. 25 



Tliird-stage larvae were kept in the experiment from July 1 to July 

 11, when the last died. They were placed upon the trunk of the tree 

 many times but climbed up vej'y little before f allmg. One specimen 

 crawled as much as 1 foot down the trunk from where it was placed 

 before fallmg and tliis was the best record of progress during the 

 experiment. 



The larvae in the tliree stages were kept under observation in the 

 experiment from June 24 to July 11 without any indications of their 

 having reached the food cage at the top of the tree. It was necessary 

 to supply the larvae with food on the ground in order to keep them 

 from starvmg. All the data secured on the habits of the larvae would 

 indicate that under natural conditions they climb very little if at all. 

 In tliis respect they possess habits very similar to those of C. calidum.
