Besides the two papers just cited the American literature on the Mites fur- 
nishes only descriptions or observations concerning single species, or pa- 
pers of a more popular character, which I cannot enumerate here; and the 
student is referred to the following European works, which have more 
or less contributed toward our knowledge of the classification of the 
Acarina.
