‘Much like Lydia Drury, 1, pl. 47, 1, but is smaller. It re- 
resembles also Nos. 21 and 68 (Lib. quadrupla), but is not the same.” 
I suppose the specimen from New York, Calverley, is from Brooklyn; 
this locality and Bergen Hill, N. J., are now the northern limit for 
this southern species.

This is a more southern species, New York (Brooklyn) in the east 
and Chicago in the west are the most northern limits.

No. 50. 6, Lib. simplicicollis Say mss. 36, Aug. 10, 1832. 
Say, l. c., p. 28, 16, adds, of the male, — I have but one specimen. . . 
Dr. Harris sent me a specimen for examination. As the male frag- 
ment in the collection is marked u, there is no doubt that it was the 
type. Massachusetts seems to be the northern limit for this species.
