This and the two following species are very close. All are some- 

 what variable and show more or less of a dorsal patch on fore wing. 

 It is least obvious in some specimens of hritana from California and 

 in kana. Specimens from the type localities can be distinguished 

 by the characters given in our key; but it is often difficult to place 

 those from new localities, D. kana differs from the others chiefly 

 in the more slanting termen of its fore wing,
