 Map XXIX. Distribution of Pulvinaria floccifera.

hydrangeae Steinweden are very similar; the
presence of submarginal tubercles in P. floccifera
which are absent from P. hydrangeae and sub-
discal setae on the anal plates of P. hydrangeae,
which P. floccifera lacks, differentiate the 2
species.

SUM-Derm membranous. Body setae (Fig. 76,
C) straight, tapering to acute points, scattered
over body. Small bilocular pores with inner fila-
ment (Fig. 76, E) scattered over dorsum. Disc
pores (Fig. 76, G) in median area anterior to anal
plates. Anal plates (Fig. 76, Ii) with

tubercles absent. VENTER -Antennae
8-segmented. Legs with tibiotarsal scleroses and
free articulation. Quinquelocular pores (Fig. 76,
M) in spiracular furrows, each furrow with 55-70
pores. Multilocular pores (most 7-loculi) (Fig.
76, N) in vulvar area and in transverse rows on
abdomen. Tubular ducts (Fig. 76, R, Q, P)
