speckled with black, except on inner sides; outer joint half as long as second, 

 exposed, dark at base. Antennse slightly dentate, whitish-green, annulated with 

 black. Thorax more of a solid pale green, patagia whitish green. Abdomen 

 light fuscous, segments darker anteriorly, anal tuft cinereous. Legs light gray 

 or pale fuscous, marked with blackish-brown on anterior tibia, annulations on 

 anterior tarsi and a spot of same on posterior tibial tufts. 



Forewing: costa slightly and evenly arched, male costal fold nearly half length 

 of wing, moderate in width. Apex rounded, terraen slightly concave between 3 

 and 7; dorsum slightly rounded. Color: whitish-gray, overlaid with shades and 

 lines of pale green, fuscous and black. A median spot of black at base with green 

 center; an oblique black dash on inner third of dorsum to middle, defining basal 

 area, above it, obliquely inwardly, a shade of greenish fuscous, not reaching costa ; 

 a quadrate dark spot on dorsum before angle, this spot is slightly oblique, is out- 

 lined inwardly and outwardly with black, between these lines it is mottled green, 

 whitish and gray. Between this spot and inner dorsal dash the ground color 

 is paler and forms a light fascia on lower half, but not defined above middle. 

 Costal fold marked with eight inwardly oblique short black dashes. Beyond 

 fold, costa is marked with four quadrate dark spots, each outlined with black 

 and greenish between the black lines, the third spot before apex sends an 

 oblique black line into ternien below apex, and an oblique line of the same color 

 from inner spot obliquely to dorsal quadrate spot. A preciliate row of five green- 

 ish spots, each outwardly outlined with black. A cluster of green scales above 

 dorsum in pale fascia between the two dark dorsal spots and a similar cluster 

 above ocellic space. The ocellic spot is not defined. An obscure, inwardly- 

 oblique, blackish shade from costa spot before apex towards quadrate spot on dor- 

 sum, ending abruptly at vein 7, and separated from the dorsal spot by ground 

 color. In very strongly marked specimens, no doubt these spots may appear as a 

 blackish, interrupted fascia. Dorsal margin maiked with seven or eight spots of 

 fuscous, greenish and black. Cilia long, gray, speckled with fuscous. 



Hindwing: cinereous gray, darker at apex and before termen, cilia paler. 



Forewing: beneath blackish-fuscous, streaked with gray along costa and ter- 

 men, cilia gray, with five or six small round dark gray dots. 



Underside hindwing: pale shining gray, cilia same. This description is prin- 

 cipally from the female, in which the black lines and scales are the more pro- 

 nounced than in the males, the black of the female is more of a dark fuscous, and 

 there are more of the greenish scales scattered over the ground color. There 

 seems to be no difference in the position and shape of spots, lines and fascia.
