On page 218 of the “Revised Manual,” in speaking of other sources than flowers from which bees collect sweets, I remark that I have seen the bees thick about a large bark-louse, which attacks and often destroys one of our best honey-trees. This is an undescribed species of the genus Lecanium.

In the summer of 1870, this louse, which, as far as I know, has never yet been described, and for which I propose the above very appropriate name, tulipiferæ–the Lecanium of the tulip tree–was very common on the tulip trees about the College lawns.

Intermediate between Briseis and Meskei. Fore wings paler than Briseis, with the t. p. line more dentate, and the brown subterminal shade paler; sub-reniform open. Hind wings red like Meskei, the middle black band broader, interrupted, transverse and not like Briseis, where it is still broader, continned and rounded, not so straight across the wing. Beneath much like Briseis, with the black bands broader and the white interspaces narrower than in Meskei. The subterminal white dentate shade on the primaries above more dentate than in Briseis. This species is similarly sized with Briseis, and is best described comparatively with that species and Meskei. Sent me by Mr. Thomas E. Bean, under the number 574, from Illinois.

Male–Expanse 1 8/10 to 2 8/10, inches, average 2 2/ inches. Upper side of primaries fuscous, with velvety discal bar and a submarginal row of gray-ochraceous spots between the nervures. These spots are usually six in number, situated in the consecutive interspaces between the nervules, beginning with the last but one subcostal interspace, counting from the apex of the wing. The second of these spots always contains a black ocellus, pupilled with white. On the fifth intersprce (last median) are usually faint indications of e fuscous dot in about one-third of the specimens examined ; in one instance this dot is distinct and pupilled with white.
