Discussion: The Galumnidae, or large-winged mites, are rather bi- 

 zarre forms which possess large, movable pteromorphs. Several species 

 are known to be vectors of tapeworms. Galumna virginiensis Jacot is 

 the vector of Moniezia expansa in the United States; G. nervosus 

 (Berlese) of Cittotaenia ctenoides in the United States and of Ano- 

 plocephala perfoliata in Russia; G. obvius (Berlese) of Moniezia ex- 

 pansa, M. benedeni, Anoplocephala perfoliata, and Paranoplocephala
