South and Central America, as indicated by the specimens so labeled 

 in the Schaus collection. Cramer's figure (Plate CCCVIII, fig. c), 

 heretofore cited to lunata, certainly does not represent that species at 

 all. Whether putrescent Guerin really belongs here I consider dis- 

 tinctly questionable. Guenee seems to consider them the same on 

 larval characters, and I am simply following- his citation without 

 further personal knowledge. 



Walker refers to viridans Guenee, and indicates its possible identity 

 with lunata Cramer. Viridans Walker, however, seems to be really 

 a form of lunata Drury, and not the species in mind by Guenee. 



Edusa Drury is merely the male of lunula, the sexual differences 

 being regarded as of specific rank. It is the form in which, the 

 terminal area is filled with blue powderings, making two lunate areas 

 on primaries and one on secondaries. 



The form named saundersii by Doctor Bethune is that in which the 

 median area becomes paler, more yellowish, and sometimes contrast- 

 ing. Inasmuch as this form occurs in both sexes, limited material 

 would easily seem to justify the separation. In the collection of the 

 American Entomological Society in Philadelphia there is a specimen 

 labeled by Mr. Grote as having been compared with type, and that 

 bears out the characters given in the description. The actual type 

 is no longer in existence. 



The involuta of Walker represents that form of Janata in which 

 the exterior lines are unusually well marked, and the darker areas are 

 along the costal region, really very much like saundersii. I marked 

 it in my notes in 1892 as being the edusa form with the blue out. 

 The possibility of error on my part is not excluded, however, for the 

 description applies more nearly to some forms of minerea which I 

 was not in position to discriminate in all eases in 1892. At all events 

 the name can not be restored for any existing species even if the 

 present reference is erroneous. 



How many, if any, of the names applied to West Indian and South 

 American forms must be cited here I am in no position to determine 

 at present.

In the essential characters of maculation this is like lunata, differ- 

 ing from that species in the somewhat smaller size and the less con- 

 trasting colors and markings. Line for Tine the ornamentation is 

 the same in the two species, but the California specimens have a 

 smoother appearance throughout, the lines are not so well marked 

 and what contrasts there are in the color and maculation are very 

 much less conspicuous.
