DISTRIBUTION 



The sycamore lace-bug is widely distributed throughout the 

 United States; it is the most common and probably the best 

 known of the Tingids. The writer has found it in every locality 

 in Oklahoma where the sycamore is grown. During the summers 

 of 1915 and 1916 it was particularly abundant in Oklahoma City, 

 Muskogee, Tulsa, Guthrie and numerous other localities where 

 the sycamore is becoming more popular, and it was a source of 

 great damage to the foliage, especially of the younger trees. 



LIFE HISTORY AND HABITS 



C. ciliata is distinctly a sycamore lace-bug and confines itself 

 to the genus Platanus so far as I have been able to learn from 

 personal observation and from data of the more recent writers 

 who have been careful to distinguish it from closely allied species 

 inhabiting other host plants. 



It is found throughout the range of the western sycamore (P. 

 occidentalis) and has been taken into new localities with its host 

 where the tree is grown for street and park shade. Although I 

 made frequent observations in the nurseries of Oklahoma where 

 the eastern plane tree (P. orient alis) is propagated, I have never 

 seen it attacking this tree, and I can find no reference in literature 

 to its having been taken from this host. Two other very similar 

 buttonwood trees are found growing wild in the Western and 

 Southwestern United States where the sycamore lace-bug is 

 found and they no doubt act as exclusive hosts. These are Pla- 

 tanus wrightii of Arizona and New Mexico and Platanus race-
