A narrow-winged Eucosnia similar in pattern to pulveratam,a 

 Walsingham, which species it precedes in our arrangement. The 

 resemblance to Bactra is only superficial, and there is a well-marked 

 costal fold which Walsingham overlooked. A series of males from 

 Sells Post Office, Pima County, Arizona (April-May, 1923), has 

 been received recently through Dr. William Barnes. These are the 

 first authentic specimens I have seen in any American collection. 



The following species now listed with the Olethreutinae are ref- 

 erable to the Tortricidae. The numbers before each are those of 

 the Barnes and McDunnough list.
