Extract

Pineus pinifoliue (Fitch) was first described (6) in 1858 under the name Chermes pinifoliae. His description of the adult gallicola migrans on the needles of white pine contained characteristic phases of the form sufficient to distinguish it from other Adeiginae. Thomas (13), in 1879, described the characteristic cone-like gall on spruce and named the species forming the gall Chermes abieticolens. In 1906 Patch (12) observed the migration of the gallicola migrans from galls on black spruce, Picea mariana (Mill.) B.S.P., to the needies of white pine, Pinus strobus L., thus proving that Chermes abieticolens Thomas was a synonym of Chermes pinifoliae Fitch. She described the nymph and adult of the gallicola migrans and sexupara and included a drawing of the adult gallicola migrans. In 1928 Annand (I) revised the Adelginae and placed the species in the genus Pineus. He described and figured the fundatris, gallicola migrans, and exsulis.
