I have compared the present species with specimens of the lat- 

 ter in the Museum of Comparative Zoology, and find them distinct. 



In galbanata the middle abdominal tuft is much larger than the 

 others, the whole insect is also larger, its color more uniformly 

 gray, and the ordinary undulating transverse lines differ in their 

 intensity and course from those of its ally. 



Head and thorax gray, faintly mottled with white and black. 



Tegulae shaped as in related species, wings gra} r , covered by 

 numerous dark gray undulating lines ; basal space dark gray, in- 

 terior line oblique, between it and the exterior line two undulating 

 lines, one of which passes before, the other around the distinct 

 reniform spot ; exterior line black and well defined, forming a 

 prominent indentation opposite the reniform spot ; the terminal 

 and subterminal lines followed by slight dull yellowish shades; 

 markings of the posterior wings corresponding to those of the 

 anteriors, except that the basal lines are absent and that there 

 are two black subparallel median lines, most prominent at the anal 

 angle. 



Beneath gray, with distinct discal dots and a common black 

 median line (in this respect differing from the Texan species). 



Hab. Glencoe, Nebraska.
