LECANIUM TULIPIFERAE Cook 4 
Tulip-tree scale 
Ord. Hemiptera: Subord. Homoptera: Fam. Coccidae 
The tulip-tree is commonly unaffected by insects, but in this large 
species of Zecaniwm it finds an enemy that occasionally causes consider- 
able injury. Several twigs from a tulip-tree, showing a very bad condi- 
tion of affairs (fig. 13), were received on October 11, from Mr Alfred 
Pell, of Highland Falls, N. Y., with an inquiry as to the nature of the 
attack. ‘The insects were so crowded on portions of the bark, that the 
old scales were huddled together and badly deformed. Under a lens 
it was seen that thousands of young had established themselves in the 
immediate vicinity of their parents, almost covering the bark in many 
places (fig. 14), while a few occurred along the veins of the leaves. The 
young were still issuing from the parents, as a number of paler indivi- 
duals were to be seen crawling over the twigs. Branches of Magnolia 
soulangeana badly infested by this species have also been received 
recently from Fishkill-on-the-Hudson. 
Earlier injuries by this species. In 1878 this scale insect was 
mentioned by Prof. Cook as one that frequently destroys tulip-trees in 

a Referred to L. ¢idzae Fitch by some authors.
