 species in preference to Toxeus. 



Mr. H. Donisthorpe, who has recently taken specimens at 

 Sandown, Isle of Wight, and has kindly communicated the data 

 (August 15th ? ; August 26th S and $ ), tells me that in each 

 instance he found the spider in company with an ant, Myrmica 

 scabriuodis, at the roots of Lotus major.
