39. Nipteria dispansa ab. infiarcata nov. 



Like the type form of dispansa Warr., bnt the oujter line is quite simply curved 

 from three-fifths of inner margin to costa shortly before apex, without any traces of 

 the furcation towards costa with the dark suffusion between the two branches which 

 is so conspicuous in dispansa. It seems probable that the present will prove to be 

 the more ordinary form, the original type representing a dark abnormality.
