 tween the bristles. 



LoNCHAEA RUFiTARSis Macquart. 



Four specimens, Nassau, June 28. Apparently a widely distributed species, 

 (New Hampshire to Mexico). With the limited material before me it is difficult 

 to define the many described species, some of which are very closely related or iden- 

 tical.
