a broad fuscous band near the base, corresponding to that on the anterior, and 

 touched with ochreons in its middle ; with a median yellowish brown curved 

 line, not reaching the costa, and exterior to this, the apical half of the wing 

 is dusted slightly with dark brownish. Along the terminal margin, is a row 

 of five black lunules, connected by intermediate metallic violet-blue spots, and on 

 the extreme margin behind these latter spots, arow of orange yellow dots ; while 

 the band is tinted interiorly with the same hue, limited by an interrupted 

 slender dark brown line near the band. 



Pennsylvania, Easton. 



In ornamentation the following species is very like the foregoing. It differs 

 from it structurally in the following respects : Fore wings with the first sub- 

 oosto-marginal and medio-posterior opposite at their origins ; the second mar- 

 ginal arises at the angle of the disk ; the apical vein forked at about its middle, 

 the lower branch entering the costa before the tip. In the hind Mings the 

 costal has a long fork ; the intercostal joins the subcostal at the point of 

 departure of the discal and seems to be a continuation of it, and the subcostal 

 is continued to the base of the wing. Head with ocelli. Tongue as long a^ 

 the thorax beneath. The first joint of labial palpi thickened with scales. 



C. ? helopalis . Fore wings white, dusted with pale fuscous toward the 

 base, and on the fold behind ; with a narrow fuscous band crossing the base of 

 the disk. Near the end of the disk is a yellowish brown line, crossing the 

 wing, deeply and acutely angulated on the fold ; and near the tip are two nar- 

 row oblique streaks of the same hue converging to the inner margin above the 

 angle, the first of which is recurved toward the disk, encircling an obliquely 

 placed oval spot of the general hue on the nervules behind the disk. Alone 

 the hinder margin, near the inner angle, are a few indistinct, iridescent spots ; 

 the margin and cilia yellowish brown. Hind wings white, with a short nar- 

 row fuscous band near the base, corresponding to that on the fore Mings ; a 

 median line of the same hue, not attaining the exterior margin and the apical 

 portion of the wing exterior to it sprinkled thickly with fuscous. Hinder 

 margin with a row of black spots, having violet- blue metallic pupils and tint- 

 ed with pale orange between the spots.

Sikonia. 



In the fore wings two distinct subcosto-marginal nervules leave the disk, 

 the first and the medio-posterior opposite ; the second marginal arising at a 

 point nearly intermediate between the two hinder branches of the median ; 

 the apical vein is forked a little beyond its middle ; the post apical and disco- 

 central arise near each other on the costal side of the wing. The median is 

 four-branched. In the hind wings the intercostal is short, remote from and 

 exterior to the upper angle of the disk. There is nothing characteristic in the 

 shape of the wings ; the posterior are broader than the anterior. 



Head with ocelli. Antennae pubescent beneath. Labial palpi, when un- 

 denuded, moderately thick and squamose beneath, ascending to the middle of 

 the front ; third joint short and rather smooth ; denuded; tapering to the tip 

 from the base, slender and cylindrical ; the basal joint long, equal to the front : 

 the second and third short and equal in length. Maxillary palpi two-jointed, 

 with tips nearly equal to those of the labial, ascending and somewhat 

 tufted at the end. Tongue scaled at base, exceeding the labial palpi by one 

 half its length. No abdominal apron peceptib!e ; the length of the posterior 

 tarsus and the tibia equal to that of the body. 



S. maculalis. Fore wings white, dusted with fuscous along the base 

 of submedian nervure ; with a fuscous spot at the base of the fold and one of 

 the same hue in the middle of submedian interspace, and a broad, irregular 

 band adjoining the disk behind, extended from the costa to the inner angle, 

 with the exterior half nearly square, and the interior somewhat paler, curved
