Pachypsylla pallida
Numerous specimens are at hand from several localities in Arizona and New Mexico which seem undoubtedly to be this species. Two of them, from Organ Mountains, New Mexico, are accompanied by galls. The latter are on the twigs and appear to be very densely pubescent; on closer examination this pubescence seems to be a dense growth of sporangiophores of a white fungus, completely covering the galls. There is no evidence to indicate whether this is accidental or whether there is some significance to this association.
