the extradiscal line. Basal line either very faint or obsolete; it is situated nearer the discal 

 spot than the base of the wing. Extradiscal line narrow, pale brown, of the same color as the 

 margin of the wing and crossing the outer third of the wing; it is irregularly scalloped ; between 

 the costa and the third cell or origin of II 4 [III 4 revised nomenclature] is a single outward curve, 

 and the line is not bent back on the costa toward the middle of the wing as in C. angulifera; 

 beliind this bend the line is scalloped on each vein, the deepest scallop being the one between 

 veins [IV X and IV, revised nomenclature], one in second median cell. Discal spot a slight 

 small trigonate pale discoloration, varying in size and shape, and in one o* entirely obsolete; 

 but when present nearly touching the extradiscal line. Beyond this line the wing is a little 

 paler, the outer edge of this transverse shade irregularly scalloped, two of the scallops in the 

 third and fourth II cell respectively like those in S. cecropia, which forms distinct black spots 

 or blotches, while the scallops in the succeeding cells are more or less distinct. Outer margin 

 of the wing clear, unspotted pale vandyke brown, and containing the distinct scalloped marginal 

 dark brown line, which is doubly scalloped, the sinuses between them broad and deep, three of 

 them are doubly scalloped, while the last one is less prominent. 



Subapical ocellus round, black, the blue semicircle distinct and the hollow partly filled 

 with pale brown scales. Above and below the ocellus cell II 2 is stained with reddish, especially 

 next to series II 2 and II 3 . The apical black mark is wanting in this genus. The subapical 

 white zigzag line is oblique; composed of two scallops pointing outward and two inward, 

 and the line ends directly above the ocellus, the first or costal scallop nearly touching the sub- 

 marginal reddish line which sweeps around and connects (being a part of) with the post-ocellar 

 brown line (this reddish line in one example is quite deeply scalloped^ at the mouth of the 

 sinus thus made is a whitish patch. 



Hind wings twice as long as the abdomen along their inner edge; with the discal spot 

 either very small and faint, or obsolete; extradiscal line faint, well scalloped, and curved around, 

 ending on the outer one-fourth of the inner edge of the wing. Outer edge of the paler brown 

 shade deeply scalloped, the points of the scallops being intervenular and ending near the series 

 of dumbbell-shaped dark-brown spots, which in one example are separated into two, forming 

 a series of two spots in each cell. This series is bounded externally by the scalloped sub- 

 marginal line. 



Under side of wings paler than above, and there is a greater contrast in hue on the fore 

 wings between the basal, median, and .submarginal portion of the wing; the discal spots are 

 more distinct, definite, and trigonate, and in the hind wings they are very long; the angle is in 

 the upper part of the cell. The zigzag line in the hind wings is more distinct and the scallops 

 are more pointed than on the upper side. 



The median space is washed with lilac beyond the extradiscal line, as on the upper side of 

 9 , and the line is white, being much more distinct than above. Submarginal spots reddish, 

 more of the shade of the upper side of the s . The apex is colored and marked much as above. 

 Expanse of fore wings, 80-102 mm.; length of fore wings, 36-49 mm. 



Female. — Antennae about two-thirds as wide as in s ■ Differs from the <? in its body 

 and wings being of a brick-red lilac hue, the darkest portion of the wing being of a brick-red 

 brown or burnt-sienna brown. Basal line well marked, broad, diffuse, dull whitish, edged 

 externally with black-brown, especially in the discal space. Extradiscal line as in <$ , but more 

 deeply scalloped, shaded within with black. Discal spot minute, faint, the shade beyond 

 irregularly scalloped as in <? , and the submarginal line as in S , so with the subapical ocellus 

 and the reddish areas. The short apical white line ending on the ocellus is divided into 3£ 

 scallops, the largest of which is nearest the apex, the two next behind pointing inward, the 

 half scallop being an incomplete one and forming a short line parallel with vein II,. Hind 

 wings with a faint basal line, the extrabasal line more sharply scalloped than in c? ; beyond 

 as in the fore wings. The wing is much lighter in hue, becoming more brick red toward the 

 irregularly scalloped outer edge of the brick-red transverse shade. The series of submarginal 

 brick-reddish spots very distinct, and they are nearly all undivided. The submarginal line 

 beyond is dark brick-red-brown. The ocellus is a little rounder than in the o* , and the blue
