NOTES ON APHROPHORA SALICIS DE GEER 
IN AMERICA. 1 
By Z. P. Metcalf and G. W. Barber 
This common European Cercopid ( Aphrophora salicis De 
Geer) was first discovered in the United States by Dr. 
Harold Morrison, who collected specimens in the Arnold 
Arboretum on various species of willow (Salix petiolaris , S. 
nigra, etc.) in July, 1921 and submitted them to Dr. Herbert 
Osborn, who identified them as above. 
According to Lallemand 2 this species is widespread in Eu- 
rope. According to Oshanin 3 it ranges from Hispania to 
“Sidemi bei Vladivostok” and from Suecia to Turkestan. 
This species was originally described by De Geer 4 as a 
variety of Cicada spumaria. It has been discussed by nearly all 
the European writers on the Homoptera from that time on. 
So far as we can discover, however, none of these writers 
give any notes on the life history. Therefore, since this 
species seems not to have been recorded before from North 
America and since it may prove to be of economic impor- 
tance, we think it advisable to record our notes on distribu- 
tion and our fragmentary notes on life history. The notes on 
life history were made chiefly during the summers of 1923 
and 1924 and since these observations did not begin until 
after the middle of June and closed in late September, they 
are necessarily incomplete. 
So far as our observations go the eggs are laid in the ter- 
minal twigs of willow, usually quite near the tips. (Fig. 8) . 
The eggs are forced into the wood and frequently there are 
a number of egg punctures close together. These egg punc-
