Imago. — Five c? , five 9 . A slightly smaller species than S. cecropia. Antennae pale as in S. 

 cecropia, not so dark as in S. Columbia. Pro thorax white as in the other species; the rest of 

 the body a little darker brick-red than in S. cecropia and much lighter red than in S. Columbia. 

 The white bands or rings on the abdomen are somewhat wider than in S. cecropia. 



Fore wings: Apex narrower, more produced than in S. cecropia, and the wing is more 

 falcate, being much as in S. Columbia. The general hue of the wings of both pairs is wine red, 

 not deep and rich purple-madder as seen in S. Columbia, while there is much more wine or pale 

 claret-red tint than in S. cecropia, though they are not shaded so black brown as in S. cecropia. 

 The base of the fore wings within the basal line is wine red; the basal line either bent angularly 

 or curved and rather more curved, and the white portion much broader than in S. cecropia and 

 a little broader than in S. Columbia and widely edged with black. The white extradiscal line 

 or band straight, not sinuous, but passing obliquely in its direction across the wing; not curved 

 outward opposite the discal spot as in S. cecropia and Columbia; it is curved inward opposite 

 the hinder end of the discal spot. It grows wider on the inner edge of the wing, and is slightly 

 scalloped on the inner side in one example. This line is not so incurved in S. Columbia or in 

 S. cecropia. 



The subapical ocellus is elongated rounded, much as in S. cecropia, but in some examples 

 more orbicular, less pear shaped. The inclosed blue semicircle tends to be wider, heavier, than 

 in S. cecropia, and the inclosed pale brown scales may be present or absent. The white sub- 

 apical zigzag line is more as in S. cecropia than in Columbia, the scallops being large, as in the 

 former species. The apical black linear spot is more as in S. Columbia than in S. cecropia, being 

 narrow, linear. 



The discal spots of the fore wings extend across the discal space and are parallel with the 

 extradiscal line; they are much smaller than in S. cecropia, varying in shape and size, but in 

 some examples much smaller and narrower, less comma-like than in S. cecropia and more as in 

 S. Columbia, they range from 6 by 3 mm. to 5 by 3 mm.; like those of S. Columbia they are all 

 white inside of the blackish edge and contain no red scales. In the hind wings they are shorter, 

 less produced toward the extradiscal lino than in S. cecropia; in this respect and in then- wholly 

 white interior they resemble Columbia. They are also more bent or curved and less comma-like 

 than in S. cecropia and less regularly oval and rounded than in S. Columbia; the longest is 10 by 

 5 mm., another 10 by 6, another 9 by 4£ mm. 



The series of black patches behind the ocellus are in my specimens not so well developed 

 as hi S. cecropia and Columbia, there being but one present, and that in the third s. c. cell. The 

 black doubly scalloped line is distinct and as hi 8. Columbia, but the inwardly directed scallops 

 are deeper and larger than in S. Columbia. 



Hind wings : The marginal spots differ both from those of S. cecropia and Columbia in being 

 round, small, while the line outside of them is more deeply scalloped, forming nearly complete 

 rings, inclosing the isolated round spots; in others the spots are not subdivided in all cases, 

 and are more as in cecropia. 



Under side of wings of nearly the same shade as in S. cecropia, but there is no red at all. 

 The discal spots, especially on the hind wings, are bordered inside the black outer edge with 

 yellow ochre instead of the brick-red of cecropia, and there is no red beyond the extradiscal line 

 in either wing. The legs are wine-red.

This species need not be confounded with either of its geographical neighbors, cecropia on 

 the east or californica on the west; it is more difficult to separate it from the northeastern ally, 

 Columbia. This species is a much paler form than either cecropia or Columbia; its prevailing 

 tint being a claret red. It differs from both of these species in the ochreous ring in the discal
