FOUR BURROWING LYCOSA (GEOLYCOSA MONTG. 

 SCAPTOCOSA BANKS) INCLUDING ONE NEW 

 SPECIES. 



By J. H. Emerton, 



Boston, Mass. 



In Psyche, Vol. 2, 1877, S. H. Scudder described the burrowing 

 spider of the Atlantic seacoast under the name Lycosa arenicola, 

 which was preoccupied by Cambridge in the "Spiders of Dorset" 

 in 1875. It was again described by George Marx in the Ameri- 

 can Naturalist in 1881 as Lycosa pikei. The upland species of

the Eastern States was described by Marx at the same time with 

 the name Lycosa nidifex. Lycosa missouriensis was described by 

 Nathan Banks in Entomological News, 1895, and again under the 

 name domifex by J. L. Hancock in Entomological News, 1899. 

 The fourth species which is described here, Lycosa wrightii, has 

 long been known without any name or description being published.
