LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 211 



(14) C. albiantennaella Wild. 



Alar expanse: 12-13 mm. 

 Locality: Buffalo, New York (late July). 

 Food plant: Cornus. 



Larval case: Gray-brown; smooth; upper edge not serrate; mouth deflected 

 to 45 degrees; posterior end as broad as, or broader than, 

 middle of case; 11 mm. long. 



This species easily distinguished from others of this group by the lack of 

 annulations on the antenna.- 



(15) C. carpinella Heinrich. 



Alar expanse : 7-7 . 5 mm. 



Locality: Maryland (June- July). 



Food plant: Carpinus caroliniana. 



Larval case: Yellowish brown; slender; smooth; mouth deflected to 45 



degrees; posterior end as wide as middle of case, flattened 



to a straight edge; 67 mm. long. 



(16) C. umbratica Braun. 



Alar expanse: 8-9 mm. 



Localities: Ohio; Virginia (middle to end of June). 

 Food plant: Prunus americana. 



Larval case: Brown; rather slender; smooth except upper edge which is 

 strongly serrate; mouth deflected from 45 degrees to 60 

 degrees; posterior end as wide as middle of case, flattened 

 to a straight edge; 5-6 mm. long. 



This species and carpinella are superficially very close. They may be dis- 

 tinguished from each other by the characters given in the table, the larval cases, 

 and the food plants; and from the other golden brown species of this group 

 (caryaefoliella and allies), by the distinctly darker shading of the fore" wing 

 towards the apex. 



(17) C. caryaefoliella Clemens. 



Alar expanse: 910 mm. 



Locality: Eastern United States (Mav-June in the South; June- July in 



the North). 



Food plants: Hickory and pecan. 



Larval case: Brown; smooth; without serration on upper edge; mouth 

 deflected to 45 degrees; posterior end as wide as middle 

 of case, flattened to a straight edge; 6-6.5 mm. long. 



This very common species is found nearly everywhere that its food plants occur. 

 It is a rather important enemy of the hickory in the north and of the pecan in the 

 south. In economic literature it is referred to as the " hickory cigar case-bearer " 

 or the " pecan cigar case-bearer." In spite of its importance, comparatively little 

 is known about it, and it should be more intensively studied. There is quite pos- 

 sibly more than one species attacking the hickory, which would account for the 

 wide range of variation in the specimens now included under this name. 



(18) C. ostryae Clemens. 



Alar expanse : 7 . 5-8 mm. 

 Localities: Pennsylvania; Ohio (June). 

 Food plant: Ostrya virginica. 



Larval case: Pale reddish brown; rather wide; smooth except for upper 

 edge which normally has a slight notch near posterior 

 end; mouth slightly deflected; posterior end as wide as 

 middle of case, flattened to a straight edge. 



Miss Braun states that she has also reared this species from hickory and con- 

 siders it a synonym of caryaefoliella Clemens. Until the latter is better known, 

 however, it would seem better to retain the two as separate species.
