on submedian fold and fiUeil with light green ; at a short distance 

 beyond, a geminate t, a. line filled with ruddy brown runs parallel 

 to subbasal line, outer line of the two being broadly black; median 

 area with small black spot in cell and a wavy black median shade 

 exterior to spot ; t, p. line geminate, almost perpendicular, slightly 

 outcurved opposite cell, incurved on submedian fold ; inner line deep 

 black, space between ruddy brown; at a point beyond t. p. line, ecpial 

 to distance between subbasal and t, a. lines, a perpendicular, hnui- 

 late, pale green line, the area beyond this being almost entirely- 

 whitish green; below apex of wing a slight black curved line, con- 

 tinued indistinctly as a greenish shade edged with dusk\- to anal 

 angle, often entirely absent; terminal black line slightly lunulate; 

 fringes rosy gray. Secondaries dark smoky gra\-, lighter along outer 

 margin with traces of black subbasal line and lighter median band. 

 Beneath smoky, banded with lighter, costa, apex of wing and fringes 

 rosy ; small discal spot on secondaries.

■'This species, which is very constant in markings in all speci- 

 mens before us, we consider distinct forms both 'improvisa' Edw. 

 and 'tear I a (sic) Edw. The latter species can at once be separated 

 by its dull gray color and lack of contrasting markings ; the median 

 area is scarcely lighter than the remainder of the wing and there is 

 no green whatever present ; Dyar is evidently in error in making it 

 synonymous with 'improvisa' Edw. The green basal area of 'impro- 

 visa is more limited than in fasciata and of a decided apple green 

 shade ; the broad suffusion of greenish in the outer portion of wing 

 bordered inwardly by geminate line is almost lacking in improvisa, 

 being confined to an apical patch continued as a waved line; the 

 course of the t, a. line also differs in the two species; in improvisa it 

 is strongly oblique below costa and well angled inwardly on sub- 

 median fold ; in fasciata it is much less oblique and the angle is not 

 prominent ; this latter distinction holds good in six specimens of 

 improvisa and eleven of fasciata compared by us." 

 My own observations entireh agree with the foregoing descriptions 

 and remarks pertaining to improvisa and fasciata. with the exception 

 that all the markings which Messrs. Barnes and McDunnough call 

 "black" are in my specimens a very dark chocolate brown. 



I will now proceed to give my reasons for considering that "impro- 

 visa" and "fasciata" are distinct from each other and the latter worthy 

 of being raised to the rank of a species.
