THE CANADIAN ENTOMOLOGIST. • 1]3 



In another specimen the pattern is the same as the above, but the 

 ground colour is more uniformly a bright or steely grey ; the brown scales 

 are nearly entirely absent, and the clothing of the head and palpi is almost 

 white, but faintly tinged with yellowish-brown or very pale fawn. On the 

 thorax of this specimen are three small pure white dots, one on each side, 

 the result of the extreme ends of the scales of the patagia being white, 

 and one on posterior edge, caused by the tips of the thoracic scales, 

 which partly overlap first abdominal segment, being white. 



In another specimen the reddish-brown scales cover nearly all of the 

 lower half of the fore wing, and in other specimens these scales are 

 coppery-brown, and in others pale brown or fawn colour. The species 

 seems to be quite variable, but a fairly constant characteristic of all that I 

 group under the name Columbia is the pair of black patches on the outer 

 half of fore wing, one before apex, parallel to and just below costa, and a 

 larger one also parallel to costa, but on a lower level, covering end of cell. 

 These two streaks, with the smaller one on the apex, make three steps, 

 each nearly an equal height above the other. 



Besides the above there are two very differently marked varieties 

 which show no intergrades, and are entitled to varietal names j they may 

 possibly be distinct species, as Dr. Dyar's breeding records of this group 

 are not entirely satisfactory to him. . 



Proteopieryx Columbia, var. albidorsatia, var. nov. — Head well 

 clothed with long smoky-black scales. Palpi fawn colour, speckled with 

 blackish, the latter predominating on end of tuft, and paler fawn on inside. 

 Thorax black, with a few very minute brown specks. Fore wing dark 

 chocolate-brown ; basal patch smoky-black, about half length of costal 

 fold, convex outwardly. On the dorsum, defined on the inside by the 

 basal patch, is a broad white band, the upper edge is excavated deeply 

 just beyond its inner end by the ground colour, beyond this it extends 

 upwards to a sharp point at about the middle of the cell, thence curving 

 downward and again upward, terminating in a sharp point on middle of 

 wing, just beyond end of cell ; the ground colour below this forms a 

 triangular patch on dorsum, just before anal ocellic spot, the base of the 

 triangle rests on dorsal margin at and before anal angle, but leaves margin 

 and indents white area, causing the latter to terminate outwardly in two 

 points. The ocellic spot is a hemispherical patch of these same white 

 scales, but a shade less white. 



In other specimens the white dorsal area is replaced by fawn-coloured 

 scales. On the costa, beyond the fold, are five pairs of greyish-blue
