Fleuritica comes close to niessoria but has a i^eculiar rusty yellowish 

 tiut to i^riiuaries which is characteristic. The reseinblauce to pUychrotis 

 which Mr. Grote emphasizes in his description I entirely fail to see. 

 The species does not appear in the synopsis as I had not recognized it 

 when that was written and have no specimens at hand now to i^lace it 

 properly. The remaining species of the larger series lack the claviform. 



Brunneigera is close to rubefactalis in appearauce, but lacks the clavi- 

 form, and the ordinary spots are indistinct. 



IncalUda is a smooth even bluish ash gray in color, the median shade 

 npright, very broad, distinct, diffuse, contrasting; the secondaries of 

 the female blackish. 



Lutulcntus is luteous in ground color, the median shade narrow, 

 vague, indefinite; secondaries of female luteo-fuscous. 



Annulipcs is a whitish gray, powdery form with a very prominent, 

 curved narrow median shade. 



3lurdocM is one of the handsomest of our species. The basal and sub- 

 terminal spaces are a bright rusty red or yellow, the median space a 

 fine blue gray more darkly shaded outwardly. It is unique in appear- 

 ance, and easily recognizable. 



QuiTKpielinea is a simply-marked, fuscous gray species of rather even 

 color, with simple black transverse lines, differing thus obviously from 

 all the other membi^rs of the subseries. The remaining species of the 

 group are smaller than any of the preceding ; not so much absolutely, 

 but habitally, seeming slighter in most cases. 



Friabilis is a very dark form in which all the markings of messoria 

 are present, sometimes quite distinctly. The general tiut is more blue 

 gray where messoria is fuscous, but otherwise the species might be con- 

 sidered as a dwarfed form. 



Fusciyera is a stdl smaller, paler gr ay, the transverse lines broad, 

 very distinct and somewhat approximate. 



Orbicularis is a paler, somewhat longer winged species, in which the 

 median lines, in contrast with the preceding, are widely separated. 



Micronyx is a very short- winged, robust species, of the typical mes- 

 soria color and general style of maculation, but the lines are indistinct 

 and the orbicular is unusually large, gray. 



Intrita is well marked; equally robust and short winged as the pre- 

 ceding, the color is a mixture of rust red and black, the lines distinct, 

 geminate, the included space pale; t. p. line unusually even. As a 

 whole, the species of each little group are closely allied, and yet each 

 affords one or more distinctive characters, the knowledge of which ren- 

 ders specific recognition easy.
