costa; the outer runs straight from just beyond the middle of the inner edge 

 of ilie wing to the costa, on which it forks, ending just before the apex; 

 beyond this line, the wing is pale fawn-brown, the apical region clear yellow. 

 Hind wings with a single, sinuate, reddish or brown line, beyond which the 

 wing is tinged with reddish, while within the line it is-inclined to lie whitish. 

 Beneath whitish-yellow, the primaries more yellow than the secondaries; the 

 outer line a broad reddish-orange hand, with the wing beyond tinged witli the 

 same color, the apical region yellowish; a brown or paler curved line on the 

 hind wings, with a few brown rleeks beyond, though these are often wanting. 

 Legs pale, a little darker at the ends of the tibia', or broadly ringed with dark 

 brown. 



Length of body, i, 0.45, 9, 0.35-0.50; of fore wing, <?, 0.55, 9, 0.47- 

 0.72; expanse of wings, 1.50 inches. 



California (Edwards and Behrens); Nevada (Edwards). 



The inner line is often obsolete, or represented by a few spots ; the outer 

 varying in depth of color, usually but little darker than the brown portion 

 beyond. Hind wings sometimes yellowish, with a brown line. A large 

 female from California, received from Mr. Behrens, differs from the others in 

 having the outer line on the fore wings obsolete between the median vein and 

 the costa, the lines brown, and the hind wings more yellowish and speckled 

 with brown scales. 



In a single male specimen from California, the costa of the fore wings is 

 arched, the wings being much broader and fuller, with a distinct, dark, trian- 

 gular, costo-apical spot, while the base of the costa is reddish, the secondaries 

 much more rounded, and the line nearer the middle of the wing and distinctly 

 scalloped, but I judge the three forms to be simple local varieties, as the mark- 

 ings vary considerably in this genus. The five Nevada individuals are smaller 

 than the others, and with narrower wings. 



Upon a careful comparison of all the specimens from all parts of the 

 country, I see no reason for not considering that all of GueneVs and my own 

 species are variations of a single species, and have, since seeing Guenee's and 

 Walker's types, been led to this determination. Guenee's 8. solfataria is cer- 

 tainly equivalent to his truncataria. Harris's type of macularia differs more 

 than any of (he others except one. One White Mountain anil a Cali- 

 fornian specimen are of the same size, and with markings almost identi- 

 cal. I do not see any good reason for GueneVs dropping Harris's name macu-
