Very like smaller eastern specimens of astrologana but with very 

 different genitalia and with under side of fore and hind wings both 

 of the same dark shade. The male genitalia are similar to those of 

 constellatana; but differs consistently in one very significant detail; 

 in constellatana the spining on the cucullus of harpe extends along 

 the arch over the neck of the harpe and fuses in with spine group, 

 Spc ^ ; while in coruscana it ends abruptly at the beginning of the 

 arch and the spine group, Spc^ is isolated. 



Male and female genitalia figured from specimens in National 

 Collection from Washington, District of Columbia (" 28-5-85 " 

 and "24-5-79").
