Discussion: The mites forming the Myobia complex are found on 

 mammals of three orders — Rodentia, Insectivora, and Chiroptera. 

 This group of mites has legs i greatly modified for hair clasping. Ac- 

 cording to Ewing 1938 they feed at the bases of the hairs on the 

 secretions in the hair follicles and seldom, if ever, suck blood. Grant 

 1942, working with Myobia musculi (Schrank), has observed feeding 

 and states, "Feeding appears to occur at other places than in the hair 

 follicles, at least the beak seems often to be inserted into the skin
