^** Pettit and McDaniel have recently (Michigan Tech. Bui. 48, Mar., 1920, p. 12-14) regarded 

 this as comi Bouche. 



^^ All the early records of the occurrence of this species in New York State apparently relate 

 to L. comi 'Qonchi. — Morr. 



2" There is a question as to the correctness of records on hosts other than oak (Morr).
