Habitat. — Cheyenne Mountain, Colorado. (G. Hofer.) 



Food Plant. — Pinus scopulorum. A single male reared under 

 Hopk. U. S. No. 13957b-2. Moth issued July 7, 1916. Habits of 

 the larva not noted, probabl}'" a needle miner. 



Type.—Cat. No. 21808, U.S.N.M. 



Close to Recurvaria milleri Busck but readily distinguished by its 

 much darker color. It differs also in characters of the male genitalia. 

 In millefi the caudo-lateral projections of the tegumen are greatly re- 

 duced while in moreonella they are conspicuously developed. Other- 

 wise these organs are much the sa,me in both species.
