"Pupa pale golden brown, 4 mm. in length, and rather stout, with 

 no especially marked characters. 



" Imagines in seven or eight days after pupation. 



" In Central Missouri the species is rather rare, and, within the limits 

 of my observation, has only occurred three times within the last dozen 

 years, although careful watch for it has been maintained upon its food 

 plant. So far it has not been found upon any Gnaphal'mm or Antennaria, 

 except G. polycephalum. I have never taken this species at light."

Dr. Clemens states that he described this species from a " single 

 specimen taken on the wing in July," presumably atEaston, Pennsylvania. 

 The type of this species has probably been lost, as I could not find it in 

 the collection of Dr. Clemens, now owned by the Am. Ent. Soc. I would 

 not be greatly surprised if it should prove to be a variety oS. bjerkandrella.

I have long had this species in my collection under the name of 

 Choreiitis colorade/la, and had so named it for others, but had not pub- 

 lished a description of it, so that Mr. Dyar's name will hold. His type is 

 in poor condition, else he would probably have recognized that it was the 

 same as my C. coloradella, specimens of which I had sent to the National 

 Museum. 



Choreutis extri?icicelia, Dyar, seems to be a badly-faded specimen of 

 the above. After a careful examination and comparison of the single 

 type specimen with all the material before me, I should not feel justified 

 in considering it a distinct species.

C. LEUCOBASis, n. sp. 



Expanse of wings 10 to 12 mm. Head, thorax and base of fore 

 wings pure white. Outer two-thirds of fore wings dark fuscous or 

 reddish brown, with an oblique, white costal streak before the apex, and 

 two others of the same colour, but much smaller, on the costa between 

 this and the white base of the wing. Outer part of the wing more or less 

 overlaid with white scales, so dense beyond the cell as to fuse and form a 

 distinct whitish patch. There are numerous clusters of metallic scales
