Discussion: The genus Glycyphagus is best known. G. domesticus 

 (DeGeer) is found in dried fruits and organic matter such as skin and 

 feathers, and is often found in enormous numbers in homes and stores. 

 G. domesticus causes the "grocers' itch" when highly infested material 

 is handled. Lepidoglyphus destructor (Schrank) (known in literature as 

 Glycyphagus destructor or cadaverum) damages certain seeds in stor- 

 age, lowering the germination of the seed. The seeds of Italian rye 

 grass and Kentucky blue grass are susceptible to mite injury. In other 

 seeds, damage is done to the already broken kernels, and as quoted 

 from Prescott 1933 "the mites live essentially on broken grains, glumes, 

 and other inert matter in the sample, and only, in certain cases, are 

 they capable of attacking sound germinable grains to such an extent 

 as to have any injurious effects on these grains." Joyeux and Baer 

 1945 report Glycyphagus domesticus (DeGeer) as the intermediate 

 host of Catenotaemia pusilla (Goeze), a cestode parasite of ro- 

 dents. This is an interesting observation in view of the role the related 

 oribatid mites play to the sheep tapeworm, Moniezia expansa (Ru- 

 dolphi ) . 



Hughes and Hughes (1938) 1939, have published on the anatomy 

 and post-embryonic development of Glycyphagus domesticus (De- 

 Geer). There is an egg, a larval, and a protonymphal stage; at the end 

 of the protonymphal stage the nymph may pass into the resting stage 

 to give rise to an active deutonymph, or it may pass into an hypopial 

 stage, remaining surrounded by the cast skin of the protonymph. This
