Pale red brown, varying to yellowish red; the colors more or less 

 mottled, uever eutirely even. Basal Hue distinct, blackish, obsoletely 

 geminate. T. a. line upright, irregular, outer line black and distinct 

 though narrow, inuer line hardly aud iu some cases uot at all traceable. 

 T. p. line geminate, puuctiform, its course sinuate. S. t. line distinct 

 pale, sinuate. The costal patch at inception of s. t. line is distinct, red 

 brown iu color. There is a dusky median shade most distinct between 

 stigmata. Claviform indicated, uever completely outlined. Stigmata 

 well sized, outlined by narrow pale aunuli. Orbicular round concolor- 

 ous. Eeniform distinctly kidney-shaped, never constricted at each side 

 of the middle ; usually paler, more or less suliused with yellowish dnsky 

 in inferior portion. Secondaries pale smoky yellowish. Beneath pale, 

 powdered with red ; a distinct dusky extra discal line ; secondaries 

 with a discal lunule. Thorax coucolorous with primaries, head paler, 

 more yellowish. 



Expands 31-33™"— 1.2-1.3 inches. 



Habitat. — Northern and Eastern States, Canada, and northward. 



This is the nearest approach to liospitalis in our fauna and is well dis- 

 tinguished from that species by the obtuse apex of primaries. From 

 rubifcra, with which the species has been confounded, it is well separated 

 by the shape of the reuiform and the costal patch at inception oft. a. line. 

 Unfortunately, I have not succeeded in getting a 5 of this species. I 

 doubt whether conJluaocGiws in America. I have never seen a specimen. 

 Mr. (jrote cites " Anticosti," but his examinations were made before he 

 recognized the distinctness of perconflua, aud I have seen specimens, 

 undoubtedly this species, labeled conflua fide Grote. Mr. Butler says, 

 Trans. Ent. Soc. Loud., 1889, 382, under Amathus jucunda Wlk., Lep. 

 Het., X, 399 {Graphiphora)^ "This is the Agrotis conflua of Grote's collec- 

 tion, but uot of Europe." 



It is very probable that Mr. Butler is right, and that Walker's species 

 is either the present species or something very like it. Mr. Grote was 

 not certain as to what was really conflua, and he has labeled more than 

 one species with this name. Without knowing exactly what Mr. Grote 

 had as conflua, it would be unsafe to substitute jucunda for perconflua.
