parasites, which usually distort its normal shape and size to a remark- 

 able degree. Many specimens collected in Ohio by the writer from 

 elm, hickory, willow, peach, etc., are so distorted that they would not 

 be recognizable if met with singly. A microscopic examination will 

 surely determine the species, however, if the unusually numerous, 

 large marginal spines are noted, along with the ordinary'' 6-7 seg- 

 mented small antennae. 



That Lecamum cocJierelli Hunter is but a parasitized and distorted 

 form of this species, is the conclusion reached by the writer after col- 

 lecting and examining many specimens along with Professor Hunter's 

 types. The fact, as reported in the original description, that the tree 

 bearing the types of this form was badly infested, and the following 

 year was almost free from this scale, would suggest almost complete 

 parasitism.
