outwardly deeply indented and black marked. There is also more or 

 less black between the ordinary spots. The female is very often quite 

 uniform in color, the markings disappearing in the uniform soft gray 

 tint, and the characteristic reniform alone showing prominently — from 

 this form to the typical strongly marked male all intergrades are present. 



This is the species most usually marked chalc'edonia in collections, 

 and which I have heretofore so determined. I have not s,Qtx\ /esiivoides 

 identified in collections but ain quite certain that this is the species in- 

 tended by Guenee. His description tallies in all points. 



The wings are comparatively somewhat shorter and broader 

 than in the other species. The harpes of the male are as in the 

 other species ; the clasper consists of a moderately long spoon-shaped 

 corneous process with a litde acute hook at tip. The species is common 

 throughout the middle slates, extending to Texas in the south-west and 

 probably to the Rocky Mountains, though I have seen no specimens 

 from further west than Missouri.

 Head, thorax and primaries grayish-brown, the costal region of piimaries paler, 

 and sometimes head, thorax and basal and costal region of primaries luteous, the re- 

 mainder of wing then of the more usual sober brown. Basal line, when present, 

 geminate ; darker brown — in pale specimens the line is wanting. T. a. line geminate, 

 outwardly oblique and somewhat sinuate, the included space somewhat paler. In 

 pale specimens the line is wanting either in part or entirely. T. p. line outwardly 

 bent over reniform, then somewhat sinuate, but as a whole outwardly oblique to the 

 hind margin. It is geminate, the inner line distinct, the outer fainter, sometimes 

 punctitorm. The hne is accompanied by a broad, diffuse whitish shade band, most 

 distinctly marked on costa and very variably distinct below that point. Beyond this 

 band the wing is somewhat evenly colored, broken into only by the pale, luteous 

 apical patch, from which starts the more or less obsolete s. t. line which is pale, 

 broken and irregular. Claviform small, pale, oval, very much of a size and form 

 with the orbicular, which is often quite indistinct or even absorbed by the pale shad- 

 ing. Reniform small, oblique, a trifle paler, black ringed.^ A black mark between 

 it and orbicular and another between it and t. p. line. Secondaries white, hyaline, 

 with margins soiled and smoky. Beneath pale, powdery, with a distinct outer line. 

 Collar with a central, darker transvei'se line. 

 Expands, .88 — 1.05 inches. 22 — 26 mm. 

 Habitat — Md. to Fla., to Texas.
