Very similar to the larger form of astrologana Zeller and fre- 

 quently confused with it. The two species have different genitalia 

 and may also be distinguished by the shape of the fore wing. The 

 latter is broader and has the termen a little more vertical in con- 

 stellatana than in astrologana. 



Male and female genitalia figured from specimens in National 

 Collection from Kansas (male) and Arendtsville, Pa. (S. W. Frost, 

 June 8, 1919, female). 



Bursa of female with signum a short hollow spine.

The larger western specimens of this species closely resemble con- 

 stellatana Zeller and the smaller eastern specimens are very similar 

 to coruscajna with which astrologana has been frequently confused. 

 In superficial characters it differs from the former in having termen 

 of fore wing more slanting, and from the latter in having under side 

 of hind wing distinctly paler than under side of fore wing. The 

 genitalia are characteristic. The species is variable as to size and 

 intensity of dark scaling on the fore wing. The small eastern and 

 large western forms could be easily separated as local races, did not
