Q. T. MOORE.
Type material of this species was distributed as P. B. -A,
No. 157, from Watch Hill, Rhode Island. This is the first
record of it other than Watch Hill and the adjacent Connecti-
cut shore. Forti, i c., erroneously locates Watch Hill in Nova
Scotia; Tilden, apparently from Forti’s statement, makes a
Nova Scotia locality as if on the authority of Holden & Setchell.
