FAMILY COCCIDE. 
Our species of this family have not as yet been investigated in 
their living state. The dried shield-like bodies of the dead fe- 
males have been met with on several of our indiginous trees. In 
addition to the species so abundant upon the apple-tree, and cur- 
rently regarded as the Coccus arborum-linearis of Geoffroy, (speci- 
men No. 872,) the following may serve as New. York examples of 
this family: The Willow Coccus, *C. salicis, is ferruginous with 
obsolete black spots, has an éval nearly hemispheric form, and 
measures 0°20 in length, (No. 873.) The Linden Coccus, *C. 
tilie, the largest of our species that have been observed, is ferru- 
ginous, hemispheric, and measures 0°24, (No. 874.) Both these 
_ species have the usual slit at the posterior end, and are wrinkled 
transversely. .
