Note 47 — PITHOEA.

By this comparison, and the subsequent allusion to an Ichneumon and a Hornet, Linnæus at the present period appears to have taken this Asilus for one of the hymenopterous order, and he even calls it an Ichneumon in Act. Upsal. ann. 1736, p. 29, n. 8. The history of its attacking the feet of cattle is given in the first edition of Fauna Suecica, 308, on the authority of the country people, but is omitted in the second, probably because Linnæus found he had been misinformed. My learned entomological friend the Rev. Mr. Kirby observes that the real Oestrus Bovis is, as has from all antiquity been believed, the cause of the above-described agitation in cattle, who escape it by running into cool damp places, which it dislikes to frequent.
