RECORDS OF UNIDENTIFIED MITES
Natural hosts.—Aglaopteryx facies, Puerto Rico (Seín, 1923): Four red "tick" nymphs found under wings of female.
Blaberus craniifer, U.S.A., Florida (Hebard, 1917): "A number of lice [mites] are present on many of these specimens [28♀♀]."
Blaberus discoidalis, adventive from West Indies, taken in Scotland (Stewart, 1925): A considerable number of mites were all over the body and hind wings.
Blatta orientalis, Germany (Cornelius, 1853): Ex sexual organs of male.
Blattella germanica, U.S.A., in laboratory (Parker, 1939): Under conditions of high humidity, the cockroaches became heavily infested with mites. In cages where the infestation was heavy, an abnormally large number of females dropped their oöthecae, and the percentage of eggs hatching was low.
Parcoblatta uhleriana, U.S.A., North Carolina (Hatcher, 1939): Hypopi of mites were found deeply embedded in the fat body of two individuals.
Mites in the hypopial stage attach to insects by which they are dispersed. Hypopi have been found in the gill chambers of a mollusk and in the gonads of a millipede (Baker and Wharton, 1952).
Periplaneta americana, U.S.A., in laboratory (Fisk, 1951): The insects were sluggish and molted with difficulty. Gold Coast Colony (Macfie, 1922): Larvae of a tarsonemid mite were found in the feces.
Pycnoscelus surinamensis, Hawaii (Illingworth, 1915): During the summer the soil was literally swarming with young of various stages. Early in September most of the adults were dead and all were covered with mites. U.S.A., Connecticut, in laboratory (Zappe, 1918a). Hawaii, in laboratory (Schwabe, 1950): Some of the cockroaches apparently died from mite infestations.

Cockroach, England? (Ealand, 1915): Cockroaches may carry the hypopial stage of the cheese mite.
