Descriptions of some New Tortricid^ {Leaf-rollers ). 

 By Chas. v. Riley, M.A., Ph.D. 



(Communicated Mar. 21, 1881.) 



The Study of the Tortricidae in this country will undoubtedly re- 

 ceive an impetus from the recent publication of Lord Walsing- 

 ham's admirable work on the Family.* Prof. C. H. Fernald of the 

 State College, Orono, Me., has been for some years devoting espe- 

 cial attention to these moths, which greatly interest the cultivator 

 of flowers, fruits, and trees, on account of the frequency with which 

 their larvae (Leaf-folders) are met with, sometimes in injurious 

 numbers. In the spring of 1878 I sent to Prof. Fernald some 

 notes upon about a hundred species of which I had studied the 

 habits and adolescent states, indicating a few of the undescribed 

 forms by MS. names. These Prof. Fernald has kindly retained 

 in his determinations, and I am under obligations to him not only 

 for this coui'tesy, but for the generic references of most of the spe- 

 cies here treated of, and for other valuable assistance in determin- 

 ations. I am likewise under obligations to Mr. Wm. H. Patton, 

 of Washington, for courteous assistance and advice, and to Miss 

 M. E. Murtfeldt of Kirkwood, Mo., for aid in rearing some of the 

 species. 



. CoNCHYLis CENOTHERANA, n. sp.— r^?. Expanse 9-10 mm. Basal half 

 of primaries yellow, apical half rose-red. Head gray. Thorax yellow, the 

 patagia tipped with gray: primaries with the basal half yellow, the costa 

 and apical half rose-red, the yellow extending as a broad median emar- 

 gination into the red ; the red portion more or less dotted or fasciate with 

 black shining scales, these scales not encroaching upon a central patch 

 which contains a yellow spot of variable size; some abbreviated black 

 and white costal streaks; posterior margin and fringes yellow, becoming 

 gray at the anal angle : secondaries and under surfaces fuscous : legs 

 silvery, the tibiae and tarsi mostly black or fuscous. Abdomen silvery- 

 fuscous, paler beneath ; ovipositor laterally compressed.
