Massachusetts was the outstanding result of a one-day collecting 
trip into Rhode Island. They were found on Carya on the edge of a 
wooded area beside Route 14 and near the reservoir. 
Corythucha coryli O. and D. 
Monroe, Connecticut, August 2, 1951; Shelton, Connecticut, 
August 27, 1958; Epping, New Hampshire, September 20, 1958; 
Diamond Hill State Park, Rhode Island, September 23, 1958. 
My collections now extend the range of this species into three more 
of the New England states for which there have been no published 
records. They were all taken from Corylus growing along the road- 
side. 
Corythucha cydoniae (Fitch) 
Newcastle, Maine, August 7, 1953; Haverhill (Ward Hill), Mas- 
sachusetts, July 27, 1957 and August 23, i960; Diamond Hill State 
Park, Rhode Island, September, 23, 1958. 
This species can now be added to the faunal lists of two more New 
England states. Since it infests shrubs and small trees of several 
rosaceous genera that are widely distributed in the Northeast, the 
single reported occurrence north of Massachusetts suggested a wider 
distribution and also raised the question of limiting ecological factors. 
The wider range is now established but the ecological conditions con- 
trolling it surely deserve investigation. I have collected rather widely 
and, in a few areas, intensively in Maine with only the record cited 
above for this species. There it was feeding on native Crataegus in 
large numbers. 
The single Rhode Island record, on the contrary, probably indi- 
cates lack of local interest in Tingids. 
The Massachusetts records are given to report another host for 
C. cydoniae. Cotoneaster hupehensis Rehder and Wilson, used in a 
permanent shrub border in a local nursery was found to be heavily 
infested. About twenty yards away is a large clump of tall Amelan- 
chier , also a part of the landscape arrangement, similarly infested. 
The lace bugs were breeding on both hosts. 
The eighth edition of Gray's Manual of Botany (Fernald, 1950) 
considers Pyracantha coccinea Roemer (a previously reported host) 
a synonym for Cotoneaster pyracantha (L.) Spach while the 1949 
revised edition of the Manual of Cultivated Plants (L.H. Bailey) 
maintains the distinctness of the genus Pyracantha. This leaves me 
with a question for the plant taxonomists to decide. If not another 
genus, we at least note another rosaceous species as a host for C.
