[256] Linn. Lach. Lapp. ii. 45. In the passage here referred to, Linné speaks of two species of Œstrus, though the mode of expression indicates that he considered them as the same. One was Œ. nasalis from which they freed themselves by snorting, &c., the other Œ. Tarandi which formed the pustules in their backs. In Syst. Nat. 969. 3. he strangely observes under the former species, "Habitat in equorum fauce, per nares intrans!" confounding probably Œ. veterinus of Mr. Clark with the true Œ. nasalis.

[262] Melittophagus, Mus. Kirby. See Mon. Ap. Angl. ii. 168. I copy the following memorandum respecting M. Melittæ from my common-place-book, May 7, 1812. On the flowers of Ficaria, Taraxacum and Bellis, I found a great number of this insect, which seemed extremely restless, running here and there over the flowers, and over each other, with great swiftness mounting the anthers, and sometimes lifting themselves up above them, as if looking for something. One or two of them leaped upon my hand. Near one of these flowers I found a small Andrena or Halictus, upon which some of these creatures were busy sucking the poor animal, so that it seemed unable to fly away. When disclosed from the egg, I imagine they get on the top of these flowers to attach themselves to any of the Andrenidæ that may alight on them, or come sufficiently near for them to leap on it.—K.
