222 THE CANADIAN ENTOMOLOGIST. 



Cosinia puiictirena, n. sp. 



Ground colour rather bright luteous, with blackish or reddish 

 powderings, so that in some cases a specimen will be almost all smoky, 

 and in another it will seem, and actually be, red. Head and thorax 

 without markings. Primaries powdery, the median lines darker, single, 

 obvious in all cases and distinct in most. Basal line single, a little 

 diffuse, not prominent. T. a. line single, oblique from the costa, forming 

 an obtuse, more or less rounded angle in the submedian interspace. T. 

 p. line single, forming rather an even and not very great outcurve from 

 costa to inner margin. Median shade obvious, sometimes prominent, 

 usually a little diffuse ; extends obliquely from middle of costa to inferior 

 margin of the reniform, forms there a rectangle and then runs parallel 

 with the t. p. line. S. t. line of the ground colour, more or less relieved 

 by the powderings on each side, and by a preceding shade on the costa. 

 Terminal space usually a little dusky. A series of more or less obvious 

 interspaceal, terminal lunules. Orbicular roiu:id or nearly so, of good size, 

 concolorous, ringed vvith darker scales, sometimes barely traceable. 

 Reniform of good size, kidney-sh^jped, more or less obviously outlined by 

 a darker line, concolorous except for a dusky spot inferiorly, which is 

 always present, even when nothing else of the spot is traceable. 

 Secondaries yellowish, silky, sometimes with a reddish flush, with a 

 narrow, scarcely defined, median line. Beneath yellowish, more or 

 less powdery, all wings with an outer line and a discal spot. 



Expands 37-44 mm. = i. 48- 1.76 inches. 



Habitat: Glenwood Springs, Colorado, September (Dr. Barnes); 

 Yellowstone Park, Wyoming, August (Dr. Barnes) ; Cartwright, Manitoba 

 (Mr. Heath). 



Four males and one female, all in fair condition, and no two alike. 

 Taken as a whole, this is a somewhat smaller form than found in the east, 

 and not nearly so bright nor so sharply marked. Yet its markings are 

 practically identical, save that the new form has, in all the examples 

 before me, a blackish spot in the reniform, inferiorly, which is not present in 

 any examples of paleacea { = discolor, Wlk., =i}ifuinata, Grt.) now 

 before me. In one specimen the median space is darkened between the 

 median and t. p. lines, making an obvious, broad band.
