in specimens with single median lines and reddish shadings. 

 Finally, with fully marked individuals without much reddish, 

 a resemblance to //nan's becomes obvious, and that is the 

 real relationship of the species. Rena is really not a near 

 ally at all, and is rather of the tessellata series. Dissona, 

 cervinea and munis are allies, and will require further study 

 from larger material to bring out fully the differences be- 

 tween them. 



Mr. Dod was good enough to call my attention to the fact 

 that the Calgary species was not identical with the Califor- 

 nian. I have only one Calgary example before me, and that 

 looks as though there might be yet another species involved. 



Euxoa indensa n. sp. 



Ground color a bright mouse-gray, more or less tinged with reddish 

 or smoky. Head and thorax without definite maculation ; head usually 

 gray powdered ; thorax reddish or brown tinged, as dark or darker 

 than any other shade on the insect, the scales slightly gray-tipped. 

 Primaries with all the normal maculation distinctly and even brilliantly 

 defined. The ground color is a clean gray, the cell intensely black 

 before and between the ordinary spots and the outer third of median 

 space is reddish, rusty or smoky. Basal line geminate, black, cleanly 

 defined. T. a. line geminate, black from costa to median vein, black- 

 ish or brown below that ; outwardly oblique and a little outcurved 

 between veins. T. p. line geminate, black on costa, abruptly bent 

 over cell, then even, parallel with outer margin; inner part lunulate, 

 well marked, outer portion even, powdery, tending to become lost. 

 S. t. line of the ground color, only a little irregular, more or less 

 defined by the darker terminal space and by a variably developed pre- 

 ceding dusky shade. A very narrow, lunate, black terminal line. 

 Fringes carneous, long and dense. Claviform small, barely indicated. 

 Orbicular large, gray, not closed above or below, clearly defined by 

 the black filling of median space. Reniform large, broad, kidney- 

 shaped, with a dark central crescent and a more or less obvious carne- 

 ous shading. Secondaries soiled yellowish white, with a smoky outer 

 border and veins in the male ; smoky, with whitish fringes in the 

 female. Beneath whitish, powdery, both wings with more or less 

 complete extra-median line and a dark discal lunule ; primaries more 

 or less dusky on disc. 



Expands, 1.25-1.35 inches = 31-34 mm.
