by dull purple-brown scales, serve to tone down any striking colour 

 effect. 



Expanse 32 to 37 mm. ; head and palpi of usual proportions, front 

 smooth, antenna? simple ; the thorax is clothed heavily, the usual tufts 

 prominent in good specimens. At extreme base of primary a yellowish or 

 whitish scale, variable as is so often the case in its degree of contrast ; 

 basal line "3" shaped, and extends half way across, enclosing an area that 

 may be whitish or more deeply stained with the tint of the ground colour. 

 T. a. line not strongly marked, irregular in its course, best defined as it 

 passes the claviform. The portion it bounds is decidedly purplish. The 

 median field is strongly yellow, of a hue not copied by any eastern 

 species here allied. Toward the costa purple shadings appear, developing 

 into a noticeable shade or bar, which connects the orbicular and lower 

 half of the reniform. The ordinary white spots are much stained with the 

 yellow of ground colour, and are probably never a very pure white. They 

 are of usual size and pattern, but not as a rule very contrasting. The 

 median shade line shows more of a departure than any other marking. 

 In lighter specimens it is best traceable ; beginning at the inner margin, 

 it bends outward, then starts across the wing at nearly a right angle with 

 costa. The point of difference lies in the angle being lower than usual, 

 and at the same time less acute. T p. line geminate, well defined, bend- 

 ing outward opposite the reniform it produces a strong curve to the point 

 of beginning on costal margin, which is directly above this spot. S. t. 

 space entirely purplish, its line is irregular and inwardly dentate 

 between the veins. The apical patch is yellow ; in lighter specimens the 

 whole terminal space reverts to this colour. 



The secondaries are more smoky in hue, with a faint deepening of 

 colour at the outer margin ; veins traceable ; fringes incline to purplish. 

 It is easy to imagine a vague, rosy flush existing in examples when just 

 emerged, making them a rather pretty species. Under side is glistening, 

 somewhat rosy, and shows the usual blending of darker scales. 



The genitalic characters exhibit no strong individuality. Three 

 examples, all from Vancouver Island, embracing both sexes, stand as 

 types ; one in the Rutgers College collection, one with Mr. W. D. Kear- 

 foot, a third with the writer. Other examples in indifferent condition 

 have beer seen, usually seeking shelter under the rutila label. The 

 species seems a western representative of the white-spotted series that run 

 so close in the east, but locally has no near relative. Its position in the
