Family Oribatid.^. 



This family is also well represented in our fauna, containing about twenty-four 

 species. They are often called Beetle mites on account of their horny-like integu- 

 ment which in appearance is like the elytra of the Coleoptera. The food of the 

 Oribatidffi is mostly of a vegetable nature, but some species are found on decay-

 varies yery considerably. Some are found under the bark of trees, others on stacked 

 roots, in cavities of stones, on gall tissue, under beards, on decaying leaves, in moss
