A long series of examples is before me from all save the last two 

 mentioned of the above localities. It establishes the species and illus- 

 trates its range of variation, which is narrow. There is a very slight 

 tendency to a reddish tinge, but nothing to cause confusion with 

 iii,s)(<'f(u from which this species is also well separated b}^ the absence 

 of a black basal streak. In some examples the indications of such a 

 streak may be made out b}' close scrutiny, but I have never found a 

 case where there was enough to give any reason for hesitation. 



Aside from this it is a mere matter of lighter or darker, or more or 

 less contrast, and this seems to depend somewhat on the age of the 

 specimen. 



The sexual and other structural characters have been elsewhere 

 defined.

Ground color a pale reddish luteous. Head a little lighter or a little 

 darker, but always uniform. Collar with a smoky or blackish central 

 lino. Thorax more reddish gray, speckled lightly with black. Pri- 

 maries streaked and shaded with ))rick red or even darker red brown. 

 Costal region always paler and sometimes white. Veins white, or at 

 least paler. Median vein white, enlarging into a little spot at its end, 

 shaded on each side so as to darken the center of the wing. A short 

 t)lack ])asal streak in the submedian interspace. A shorter dark 

 t)rown or blackish streak on the hind margin near base. Transverse 

 posterior line black, punctiform, evenly curved. An oblique brown 

 shade over the anal angle and a second from vein 2 at the transverse 

 posterior line to outer margin below apex. The white veins are often a 

 little expanded at the base of the fringes. Sometimes a series of small 

 terminal black dots, rarely an almost continuous brown line; often 

 neither. Secondaries whitish or yellowish at base, darkening out- 

 wardly to smoky or blackish; fringes with a yellow line at base. 

 Beneath, primaries reddish gray, powdery, with a smoky costal dot 

 from which starts a variably complete punctiform extra median line;
