This insect is 'described by Curtis, in his " Farm Insects," as one of the correctives of the wire-worm beetle. He found it on Elater ruficaudis, and it attaches itself to various other insects. Hermann says he found it on Elater, Tipula, and spiders.

De Geer took it for the Acarus phalangii, and Curtis followed him, but seeing that it was only six-footed, rightly put it in the old genus, Leptus, proposed for the six-footed Acari, before it was known that they were only the young of other species. The true genus to which this belongs, however, is easily gathered from the snouted mouth and extended palpi: and Curtis's figure, which we give here, is un- mistakably only an individual of the Scirus insectorum figured by Hermann, not so well filled up as his specimen.
