lobes to the penultimate segment. Between the third and fourth pairs 
of spines, there are three or four irregular, spine-like extensions of the 
margin of the segment. Four or five groups of circumgenital gland- 
orifices are present; Median, 0-6, (rarely more than three); anterior 
lateral, 5-14; posterior lateral, 4-8. Rows of dorsal pores sometimes 
quite prominent. 
Remarks: This seale popularly known as ‘*Putnam’s 
Seale,’’ is not an important economic insect per se, but the possi- 
bility of mistaking the San Jose’ Scale for this one, attaches to 
it more importance. The seales are lighter in color, and the ** dot 
and ring’’ is not nearly so prominent as in the San Jose’ Seale. 
Remedial measures for the latter are fully as effective for Put- 
nam’s Seale.

Scaie of female: The shape depends upon the position upon the 
leaf, but usually approaches a semicircular form, attached close to the 
midrib, veins or veinlets of the leaf. Length, 1.5--2 mm., width, 0.5— 
1mm. Large, rather flat, cream-buff, excepting the part which covers 
the exuviae which varies from yellowish to reddish-brown, or is often 
concolorous. 
Scale of male: Length, 1mm., width 0.5mm. Cream-buff or 
grayish-white, semi-transparent, more or less elongate oval. Exuvia 
submarginal. 
Female: There are two pairs of well-developed lobes, the second 
pair often as long or longer, and as broad as the median pair, which 
are commonly notched on the lateral margins near the tip. Plates 
conspicuous. Between the first and second lobes, they are more or less 
toothed and about as long as median lobes; laterad of second lobe is a 
broad circular fringe; laterad of this are three Jarge toothed plates. 
Spines prominent; a pair at outer base of median lobes, a pair at outer 
base of second lobes, the third on the rudimentary third lobe, and the 
fourth just laterad of the plates. Four groups of circumgenital gland- 
orifices; anterior lateral, about 6; posterior lateral, 4. 
Remarks: Found on the leaves of Sugar Maple. (Acer 
saccharum) at Columbus. Ohio, associated with Phenacoccus 
acericola (King).
