Remarks. — This species was originally described from Somers 

 and Beesley's Points, where it was discovered in April of 1871. 

 It burrows in the sand of the beaches, just above ordinary high- 

 water mark, in company with Talifrus longicomis, and several 

 species of beetles. It makes a little conical mound of sand around 

 the aperture to the burrow. Its distribution is from Massachu- 

 setts to Maryland.
