Very little size variation is found to occur, this entirely irrespec- 

 tive of geographic distribution. 



Coloration.— Head ochraceous-buff to ochraceous-tawny, with a 

 broad band of dark chestnut brown between the eyes;^ in several 

 specimens from extreme southern Florida before us, this marking 

 is continued on the face, forming a large triangular blotch, with a 

 small additional marking at its apex at the clypeal suture. Pro- 

 notum transparent luiffy; disk marbled with very weak ochra- 

 ceous orange, bordered rather narrowly with blackish brown, this 

 marking broader and solid caudad to the caudal margin of the 

 pronotum, disk further marked wath this color in the shape of an 

 anchor, the two adult females from extreme southern Florida and 

 fourof theBahaman adults have this marking subobsolete. Tegmina
