Extract

Chermes alni Kalm. Travels into North America, English translation, vol. 1, p. 154; p. 121, 2nd ed.

Eriosoma tesselata Fitch. 4th Report State Cab. Nat. Hist., N. Y.

Eriosoma tesselata Glover. Ag. Rept., 1876, p. 39.

Eriosoma tesselata (or imbricata) Glover, unpublished plates Homoptera iii., fig. 19.

Schizoneura tesselata Thomas, 8th Report Insects of Illinois, p. 139.

Apparently the first record of this insect is given by Kalm., as cited above, where he says under date of Oct. 3rd, 1748: “I saw to-day the Chermes of the Alder (Chermes alni) in great abundance on the branches of that tree, which for that reason looks quite white, and at a distance appears as it were covered with mold.” This reference, in all probability, is to P. tesselata, and the reference to the European species, Chermes alni L., a mistake, since there are no later records of the European species being found here, and this one is specifically distinct from the one described by Linnæus.
