CATERPILLARS AS ANTS' PETS. 595 



In order not to forget the practical side of these notes I venture to 

 ask the kind help of the members in the matter. Our Society will be 

 very thankful for any specimens of well-determined caterpillars of 

 the Lyccenidce, either blown out or preserved in alcohol, formalin, 

 etc., and for ants that have been observed in company with caterpil- 

 lars or pupae. Equally welcome are observations concerning the 

 relations between ants and caterpillars.
