 hne indicated by costal s[)ots only ; t. p. line piinctitorni and very indis- 

 tinct ; the i)oints venular and very small ; a terminal row of trian<;nl;ir

 with black ; beneath white, powdery; primaries somewhat darker. 



Expands 37-40""", 1.50-1,00 inches. 



Habitat. — Canada ; United States, west to the Mississippi, south to 

 Georgia. 



This species is not uncommon and is very easily distinguished by its 

 bright color and almost entire lack of maculation. 1 have taken in on 

 golden rod in September during the day. 



Mr. Grote in commenting on I\Ir. Walker's species says the type is a 

 white Af/rotis very much rubbed and scarcely recognizable. Should the 

 suggestion that it is the same as muraenida i)rove well founded, vvtiista 

 must, 1 am afraid, be used for this species. 



Porosagrotis catenula Grt. 



187U. Grt., North Am. Ent. i, 44, Jf/rotis. 



Pale, yellowish gray, i)owdered with black atoms; ordinary spots very 

 indefinite, blackish ; t. a. Hue evident though not very distinct, single 

 with three outward curves, that below vein 1 widest; t. p. line nearly 

 parallel with outermargin, strongly crenulate, tending to become puncti- 

 form ; a distinct black dot preceded by a clear white dot marking each 

 vein; a row of terminal luuules; secondaries white, sometimes with 

 smoky outer border; beneath white; primaries blackish on disc. 



Expands 31-39""", 1.2.')-1.55 inches. 



Habitat. — Colorado, Montana, New Mexico. 



Closely allied to mur((eHuh(, from which, however, it differs in the 

 yellowish tint to primaries and the well-marked transverse lines. It is 

 undoubtedly the western repx'esentatlve of that species and may possi-
