cydoniae which thrives on many native and cultivated forms in this 
plant family. 
Corythucha marmorata (Uhler) 
Bradford, Massachusetts, July 6, 1957; Haverhill (Ward Hill), 
Massachusetts, July 27, 1957. 
This species ranges throughout North America. In New England 
it feeds exclusively on a diversity of herbaceous composites. Apparent- 
ly one of America’s most successful Tingids in terms both of its wide 
distribution and of its local abundance, it is the only species of the 
fifteen in the genus occurring in New England that is neither arboreal 
nor thamnophilous. Its catholic preference for ubiquitous composites 
undoubtedly accounts in no small measure for its success. 
Consequently, it was not surprising to find it thriving on two 
species previously unlisted. The Bradford observation was made on 
Rudbeckia serotina Nuttall, the common Black-eyed Susan or Yellow 
Daisy. On Ward Hill they were found on the cultivated Globe 
Thistle, Echinops sphaerocephalus L. 
Corythucha mollicula O. and D. 
Monroe, Connecticut, August 2, 1951; Newtown, Connecticut, 
August 2, 1951; Aurora, Maine (collected by Dr. A. G. Humes), 
July 13, 1950; Rockport, Maine, September 10, 1958; Sheepscot, 
Maine, August 6, 1953; Petersham (Harvard Forest), Massachu- 
setts, July 18, 1951; Diamond Hill State Park, Rhode Island, Sep- 
tember 23, 1958. 
Probably again because of lack of collector interest, few records 
have been published for this species. Therefore, these, all from Salix , 
are cited.
