I have bred adults from Virginia material on December 5 
(1928), and this is probably an average date for the appear- 
ance of the insects. 
Osten Sacken’s original description does not accurately de- 
scribe the surface of the insect, probably because of the lower 
magnifications he employed. The types, from Washington, 
agree with the New York specimens. Beutenmiiller’s state- 
ment that the parapsidal grooves closely converge at the 
scutellum does not agree with the American Museum speci- 
mens I have examined, altho these were probably the insects 
on which that author’s descriptions were based.
