Adults of both sexes of this spider were sent to me by 

 Dr. A. R. Jackson, M.D., &c., by whom they were found at 

 Box Hill, Surrey, in June, 1911. It is only very recently 

 that this spider has been noted as British ; it is nearly 

 allied to the rather larger and more strongly marked 

 species, Micariosoma festivum, C. L. Koch, which is 

 widely dispersed and abundant, and with which the 

 present might easily be overlooked.
