SCALE INSECTS OF THE GENUS PARLATORIA 31 
k. Submarginal tubular ducts relatively 
few, 20 to 29 per side; fully developed 
pygidial lobes almost equal in size, 
third, or outer, pair very little 
smaller than median pair; paragenitals 
few in number, 19 to 31 in material 
studied; pygidial sclerotic fleck an- 
terior to fourth lobe_ camelliae Comst. 
kk. Submarginal tubular ducts usually rela- 
tively numerous, averaging around 51, 
but ranging from 26 to 95 in material 
tabulated; fully developed pygidial 
lobes obviously graded as in pergandii, 
third, or outer, pair definitely smaller 
than median pair; paragenitals rela- 
tively numerous, total averaging 
around 60, but ranging from 25 to 84 
in material studied; pygidial sclerotic 
fleck in interspace between third and 
fourth segments. 24552 = theae Ckll. 
jj. Fourth lobe practically indentical in appear- 
ance with adjacent plates; posterior and 
anterior groups of paragenitals normally 
fused into a single band on each side of 
vaginal opening, but this band narrowed 
near its middle; normally without micro- 
ducts above anterior paragenitals or along 
anterior edge of pygidial sclerotized area, 
but such tiny ducts present on anterior 
abdominal segments; no sclerotic flecks on
