blance to Camponotus <sneopilosns, Mayr, while a third imitates 

 the form of some of the species of the genus Folyrhachis, even to 

 the golden pile upon the abdomen. 



Since these spiders are only found in places where the ants that 

 they resemble are also found, and as the latter are frequently 

 found without the mimetic spiders, it is evident that it is the 

 spiders which benefit from their striking resemblance to their 

 hosts. 



In concluding these notes, I would like it to be understood 

 that they refer only to the Formicidm collected in the immediate 

 district, as under different conditions and surroundings it is 

 very probable that the same species may vary both in the con- 

 struction of the nest and the site chosen. 



My thanks are due to Mr. W. W. Froggatt for notes and 

 assistance in preparing this paper.
