Male. — Expands 1.5 inch. 
Upper side greenish-yellow or greenish-white, usually much and uniformly ir- 
rorated with gray-brown over entire surface ; sometimes but little however on the 
disks, though densely on the hind margins, in which case there is formed thereby 
a broad marginal border ; both wings have a sub-marginal series of oval spots, 
the color of the ground, not very well defined, being more or less dusted with 
brown; those of secondaries often incomplete, and some of them, especially next 
inner angle, often lost in the prevailing brown shade; discal spot of primaries 
small, black, of secondaries small, pale yellow, often indistinct; costal edges and 
fringes roseate. Under side of primaries either greenish-yellow or white, the 
apical region washed with yellow, and surface more or less densely dusted with 
gray-brown; the discal spot black inclosing either a pure white space, on which 
are a few roseate scales, or the space is of the ground color, without roseate ; 
beyond the disk a transverse row of brown points, obsolete except two or three 
next inner margin; secondaries dark green, or often greenish-yellow, the hind 
margin paler, and the whole surface densely covered with brown scales; discal 
spot white with a few roseate scales, and a dull red narrow border, a spur of 
same red often projecting posteriorly; or sometimes there is a roseate point 
outside the discal spot in direction of outer angle; a small red patch at base of 
wing:.
