Insects of this order were found in the stomachs of seventy- 

 three frogs, consisting of one imago, one chrysalis, and one 

 hundred and twenty-one caterpillars. These larvae were 

 eaten indiscriminately and constitute one of the most import- 

 ant foods. Such hairy caterpillars as the larvce of the Tiger- 

 moths and Fall Web-worms were present in several stomachs. 

 Frogs taken at night or in the morning contained such noc- 

 turnal larvae as cutworms (Agrotinae). 



Lepidopterous larvee are so easily digested that in many 

 stomachs they were ground up beyond specific recognition 

 and could not be identified beyond the family.
