NEW SPECIES OF THE GENUS GRACILARIA 



AND NOTES ON TWO SPECIES 



ALREADY DESCRIBED 



(Lepidoptera, Gracilariidce ) 

 By CHAS. R. ELY 



Gracilaria burgessiella Zeller. 



(Verb, zool.-bot. Ges. Wien, xxiii, 307, 1873.) 



This species was described by Zeller from a captured speci- 

 men from Beverley, Massachusetts. 



During the latter part of July, 1912, the writer bred two 

 specimens of this insect, and in July, 1914, four more, from 

 typical Gracilaria cones in the leaves of Cornus candidissijna 

 Marsh. The imagoes emerged July 3()-August 1. 



The mine which the larva makes is on the under side of 

 the leaf, narrow and winding at first, but quickly terminating 

 in a small, elongated blotch, next to a rib or vein. After 

 emerging from the mine the larva rolls the tip of the leaf 

 downwards into a small cone. It leaves the cone to spin its 

 cocoon, which is similar to those of our common maple and 

 willow feeders. 



On the same bushes, from which this material was collected, 

 were found leaves which had been formed into cylindrical 

 rolls, the leaf being rolled from the side. The inclosed larvse 

 were badly parasitized and no imagoes were reared. These 

 rolls may also be the work of burgessiella Zell., but the author's 

 experience would lead him to believe that another species is 

 represented. 



This insect is probably not very abundant. The numerous 

 records of burgessiella Zell. in the various lists usually refer to 

 the very common species which feeds on red maple.
