costa and extradiscal space the line is straight and divided into l.vvo shallow 



scallops, I lie lower being (lie more pointed ol the two (in (J. pampinaria, the 

 upper scallop is represented by a prominent double tooth); below, the line 

 curves inward, with a similar outward curve, and then the line curves out- 

 ward, ending on (lie inner edge of Ihe wing; a broad, pale, chocolate-brown 

 shade borders Ihe line externally; the usual distinct, zigzag, while line 

 inclosed in a dusky area ; a whitish subapical patch ; a row of marginal, 

 small, round dots, each dot sending a faint black streak inward. Fringe 

 concolorous with the wing, not checkered. Hind wings with a black line at 

 (he extreme base (sometimes wanting) ; middle line broad, diffuse, straight ; 

 outer line linear, with a distinct point opposite the discal dot in the more 

 typical form, or the point obscure ; the line varies in its distance from the 

 narrow, large, discal ringlet; the line shaded beyond with pale chocolate; 

 submarginal zigzag line and edge as in the lore wings; beneath, usually with 

 no markings, except three faint costal spots, and discal spots and marginal 

 spots. Surface of both wings uniformly dusky-ash, a little darker than in 

 C pampinaria; in one specimen, a faint submarginal, dusky shade. Abdomen 

 with a narrow black stripe at the base, but Ihe basal ring not conspicuously 

 white, as in C. pampinaria; two rows of dorsal black spots along the abdo- 

 men. Anterior legs grayish, with paler rings.

. This variable species is nearly as common as C. pampinaria, and differs 

 from it in the very sinuous outer line, Ihe more oblique, less curved, inner 

 line of (he fore wing, by Ihe distinct discal ringlets on both wings, and by 

 the absence beneath of the submarginal dusky shade. Walker's Phibala- 

 pteryx erosiata is a rubbed individual, with very broad, suffused, black lines. 

 1 have it from Maine. Another variety, which 1 did not see either in M. 

 GueneVs collection or that of the British Museum, is chocolate-ash, with 

 the chocolate bands twice as broad as usual.
