Close to and possibly a pale race of siniidana; differs chiefly in the 

 much heavier dusting of ochreous scales on outer half of fore wing. 



Genitalia figured from specimens in National Collection from Pitts- 

 burgh, Pa. (Henry Engel, " V — 29 — 65," male type) and Cincinnati,

Distiihution. — Pensylvania, Ohio, Wisconsin. 



Alar expanse. — 14 — 15 mm. 



Type. — In National Collection.

6. DICHRORAMPHA INCANANA (Clemens) 



(Figs. 108, 279) 



Halonota incanana Clemens, Proc. Acad. Nat. Sci. Philadelphia, 1860, 

 p. 351. 



Hemimene incanana Fernald, in Dyar List N. Amer. Lepid., no. .5288, 

 1903.— Busck, Proc. Biol. Soc. Washington, vol. 19, 1906, p. 179.— 

 Barnes and McDunnough, Check last Lepid. Bor. Amer., no. 7254, 

 1917.— Forbes, Memoir 68, Cornell Univ. Agr. Exp. Sta., 1924, p. 389. 



Hemimene nigromaculana Kearfott, Bull. Amer. Mus. Nat. Hist., vol. 23, 

 1907, p. 159. — Barnes and McDunnough, Check List Lepid. Bor. Amer. 

 no. 7264, 1917. 



The type of Clemens' species, a small male with distinct costal 

 fold (yellow label. No. 1437), is in Philadelphia. It agrees with 

 Kearfott's nigi'omaculana except that the latter is somewhat larger. 

 Kearfott described from two specimens, but I am able to locate only 

 one (the female type in the American Museum). He had other 

 specimens under liis name, but these are incorrectly determined. 

 They are Grapholitha prunivora Walsh. Aside from the Clemens 

 and Kearfott types I have seen only one other specimen of the true 

 incanana, a male in the National Collection from Falls Church, Va. 

 (Heinrich, "6—6—17"). 



Male genitalia of this last figured; female genitalia figured from 

 type of nigromaculana. 



Alar expanse. — 8 — 10 mm.
