Remarks: P. citri is one of the greatest worries of nursery- men on Coleus, and was also quite common in the Cape Peninsula on Oleander. Pseudococcus lounsburyi n. sp. Ovisac: When complete entirely enclosing the adult 9 , large, elongate, oval, composed of threads which, when seen under the micro- scope have almost a glassy appearance; mm. long, by mm. broad. Large numbers of ovisacs were often found mat- ted together between leaf-bases, some- times forming a mass two inches long by almost as wide. Ova: Closely surrounded by fibres of the ovisac; orange yellow, 340 n long by 176 M in diameter. LarvcB: Newly emerged, are nearly transparent, showing but the slightest tinge of the usual purplish coloring 680 /x long and 260 /x broad; antennae trans- parent, of 6 joints. Male: Puparium small, brownish white. Adult of the usual Pseudococcus (^ form (see figure) with body purplish red in color, .9 to mm. in length and .255 mm. across the thorax, the widest part of the body; legs and anten- nae pale yellow, and semi-transparent.
