about Acari eating eggs, so the fact seems new and is very important." The 

 Dermalcichus figured in my 5th Mo. Rep. (p. 87) feeds upon the eggs of 

 Mytilaspis pomicorticis, as well as upon the insect proper under the scale. 

 In fact I find it more often feeding on the eggs. Dr. Packard long since 

 observed and figured a mite ( Nothrus ovivorus) that preys on the eggs 

 of the Fall Canker-worm ( Atiisopteryx pometaria Harr.) ; while the bene- 

 ficial effects of the Locust Mite (Trombidium locustarum) in destroying 

 the eggs of the Rocky Mountain Locust have been frequently referred to 

 of late years in my Reports, and recently in the February number of the 



American Naturalist.

 and as this name has priority, antholea falls.
