VOL. XXXV. 



fuscous, banded above with blackish on posterior segments. Legs 

 crean\y ochreoiis, anterior pair heavily dusted with fuscous. 



Fore wing white, overlaid with fuscous and blackish brown. The 

 white occurs as follows : A broad median streak from base to end of 

 cell, a fine line on fold, and a dusting on dorsal margin below fold ; 

 all veins on outer half of wing overlaid in white; between veins 5 

 and 8 the white predominates; at the termon the white forms a con- 

 tinuous band. The fuscous oc- 

 curs along costa, between median 

 white band and fold, below fold 

 and between veins in outer half 

 of wing. The blackish brown 

 occurs only as fine lines, outlin- 

 ing vein 1 '', all veins between 

 end of cell and termen, and is 

 rather heavier between end of 

 cell and apex than elscAvhere. 

 The terminal line is ocherous

fuscous; it is close to termen, and is sharply angled below costa and 

 dentate at lower end. The subterminal line is of the same color, but 

 somewhat obscure; it follows end of cell, then sharply angles out- 

 ward halfway to termen in a tooth-shaped process, the lower half 

 of which runs backward to inner third of dorsal margin ; it is lightly 

 outlined with white on both sides. The terminal line is outwardly 

 edged with a row of dark brown dots. The cilia is shining leaden, 

 cut by white on the upper half. Pre- 

 ceding the cilia is a line of black dots 

 and lines; between the veins there are 

 four short lines on upper half of wing, 

 three dots below them, and a nearly con- 

 tinuous line of tornus. 



Hind wing light fuscous, with a fine 

 darker marginal line, which at apex is 

 preceded by a few whitish scales; cilia 

 white, divided by a pale fuscous line at 

 base. Underside both wings grayish 

 fuscous; both are margined outwardly with white, Avith the mar- 

 ginal and ante-ciliate lines and dots repeated. 



One male specimen, from Baboquivaria Mountains, Pima County, 

 Arizona, latter part of July, 1903, collected by Mr. O. C. Poling. 



Type. — In Author's collection. 



This species is remarkably like T. repanda Grote, and the only way 

 to distinguish them is by the difference in the male antenna?, an 

 enlargement of both, with head structure, is shown by figs. 10 and 11.
