and wings arc of a uniform fawn-color, the scales being thick and close. 

 The basal line is angulated on the median vein, extending thence straight to 

 the costa, and below the median vein its course to the inner edge is oblique 

 and slightly sinuous. The outer line pale testaceous, like the inner, but a 

 little more distinct, and slightly sinuous; it is situated half-way from the 

 inner line to the outer edge of the wing. Apex very acute, median angle 

 large, as is that on the hind wings. A minute black discal dot on both wings. 

 On the hind wings, the single straight pale line is a little broader than on the fore 

 wings. Fringe short, testaceous, a little reddish at base, especially toward 

 the angles. Abdomen a little paler than the thorax. Beneath, the wing is pale 

 ochreous, with dense black strigse, often confluent; both wings are shaded 

 with a slight ashen tinge on the outer edge; on the fore wings, the strigge 

 unite in diffuse patches, forming an irregular broad band on the outer third 

 of the wing ; fringe as above. 



Length of fore wing, 0.87 ; of body, 0.72 ; expanse of wings, 1.50 

 inches. 



W. Springs, Cal. (Behrens). 



Another individual from California, taken by Mr. Behrens October 16, 

 is ochreous, with the tawny-brown lines and the inner line on the fore wings 

 much curved. 



This fine species may be recognized by its large size, uniform fawn- 

 color, the simple antenna?, and the two testaceous lines on the fore wings, the 

 inner line being curved regularly.

1 $. — Head smooth in front. Palpi large, extending far beyond the 

 front of the head. Antenna? with moderately long pectinations. Fore wings 

 with the costa sinuous, falcate, the outer edge not excavated as much as 

 usual, with a slight projection half-way between the apex and the median 

 angle, the latter not so prominent as usual. The angle on the hind wings is 

 well marked, much as in T. truxaliata. Body and wings pale ochreous. 

 Fore wings with the inner line broad, diffuse, curved outward, not well 

 marked; the outer line scalloped, sinuous, curved outward beneath the 

 costa ; the line is made up of a fine black line, with the shallow scallops 

 filled in with white scales, with a broad brown shade beyond. Hind wings 

 with traces of a straight dusky line; both wings speckled transversely with
