This species, E. araucarice, Mask., and E. ade?iosto}n<e, Ehrh., 

 resemble each other so closely externally that they cannot be distin- 

 guished by their external appearance. Araticarice and adenostomce. resemble 

 each other in the spines, but araucarice. has the spines rather more 

 conspicuous, especially a row around the margin, which do not clear as 

 easily as the rest, and therefore stand out rather prominently. In 

 araucarice the tibia and tarsus are subequal, while in Gillettei the tarsus 

 is distinctly longer than the tibia, in adenostotnce they are nearly subequal. 

 The length of the third joint of the antennje in Gillettei is between those 

 of the other two. Araucarice has the caudal lobes distinctly prolonged, 

 while that is not true in either Gillettei or adenostovue. 



This species seems to be of economic importance, as Prof Gillette 

 writes : " The little trees from which I took these specimens seemed 

 almost to be dying from the attacks of these insects. At first I thought 

 the trees literally covered with some chionaspis on bark and leaf
