Since })ublishino; on the variation of the venation of this species 
(Ent. news, vol. 12, p. 305, 1901) specimens showing the following ad-

Massachusetts, June 16, has an adventitious cross-vein in the third 
posterior cell. One from Danvers, Massachusetts, Sept. 23, 1908, 
has on the left wing five adventitious cross-veins in the second sub- 
marginal, and one in the second posterior cell; the right wing has one 
cross-vein in the first submarginal near the outer end, and four in the 
second submarginal cell. A specimen from Riverton, New Jersey, 
has two of the three cross-veins in the second submarginal cell on the

original localities — District of Columbia and White INIountains, New 
Hampshire — is now well filled by specimens received and collected
