348 AMERICAN LEPIDOPTERA. 



All the iiKirkings are distinct, and the median shade, which tends 

 to become prominent, is very much like that of verberata in course. 



Straminea Smith is a small species, straw- yellow in appearance, 

 with all the maculation present but not conspicuous. The s. t. space 

 is somewhat darkened by a smoky shading and the reniform is dusky 

 interiorly, as usual. The secondaries, while they are pale, are dull, 

 with a smoky tinge, and there is a darker outer border. 



The second series, with the antennse of the male ciliate only, is 

 the equivalent of Hampson's Section III ; but this contains two 

 series more widely distinct than the difference between the series 

 distinguished on the autenual character alone. 



Superficially all of these species, except inops, differ from all the 

 preceding in that they have a punctiform s. t. line; and in gen- 

 eral that line is preceded on the costa by a distinctly darker patch 

 filling the s. t. space at that point. But that is a somewhat variable 

 character, and while in the series it stands out conspicuously in each 

 species, yet individuals occur in all of them in which the point is 

 obscured. 



A series of three species, antapica, purpurea and Jorniea have the 

 primaries somewhat elongate, with acute apices, even or slightly 

 depressed costa and the outer margin a little excised below the apex. 

 There is a tendency to the darkening of the s. t. space, and the ter- 

 minal space is concolorous or even a trifle paler. 



The sexual characters of the male agree remarkably in the form 

 of harpes and clasper. Only in purpurea were the supra-anal plate 

 and uncus examined, and in that species the latter is broad and flat- 

 tened, altogether unlike the slender hook of the species in the pre- 

 ceding series. The harpes in all the species are narrow, elongate, 

 drawn out to a long point ; not so markedly unlike the bicolorago 

 type, but even narrower with a longer point. The superior margin 

 of the harpes is thickened at base and to the middle, and then the 

 chitinous thickening extends obliquely across to the inferior margin 

 and may extend almost or quite to the tip. From the oblique 

 thickening and almost at the middle of the part a rather stout, 

 moderately long, curved hook arises, which becomes more slender 

 toward the tip, but ends bluntly. Only in antapica does this hook 

 seem to be absent; but 1 believe that to be due to defective material 

 rather than to a real divergence from its allies. Toward the apex 

 and a little nearer the inferior margin is a chitinous, short, stout.
