One 9 . Denver, Colo., Sept. 10th, Oslar. 



This species is of the same shape and general appearance as cram- 

 bitana and canariana. I would not venture to describe it from one 

 9 except that it can be easily recognized by its uniform wing col- 

 oring without marks of any kind.

Head and thorax pale brown ; antennse pale brown, dusted with darker brown 

 outwardly; antennae clay-yellow; abdomen and legs pale fuscous, latter dusted 

 with light brown. 



Forewing: clay-yellow, rather heavily overlaid with pale pinkish terra-cotta- 

 brown. Tliere are no well defined fasciae or spots; the darker shade forms an 

 obscure triangular patch, with base resting on dorsal margin between inner and 

 outer fourths, the point of the triangle reaching top of cell a third from base. On 

 the outer third are vertical irrorations of shining clay-yellow. The edge of the 

 costa is reticulated with the two shades. Cilia clay-yellow, inwardly edged with 

 a slightly darker line.

 whitish. Underside the same.

 va)ia Wlsm. and larana Wlsm.
