of the scale is grayish in color; the outside surface is wholly covered in all cases, 
with a fungus of a grayish-brown color, obscuring the color of the scale so that it is 
impossible to distinguish it. 
g . Scale is quite distinctly tricarinate, 1^3 to \]/ 2 mm. long, % mm. wide 
white; exuvium at one end, brownish-yellow or yellowish-brown. The $ scale is 
different in texture from that of the 9 . 
9. After boiling, subcircular, tinged with brownish-yellow at least anally. 
Three pairs of lobes, the median largest, almost imperceptibly excavated on their 
outer posterior border, very slightly notched on inner posterior border, about as wide 
as long, slightly separated, not contiguous. Second pair of lobes subround, rather 
less than one-half the width and length of median lobes, each removed by about its 
own width from median lobes, entire. Third pair of lobes small, about half the size 
of the second pair, appearing as tubercles on the margin, removed from second pair 
a distance equal to rather more than twice their diameter. Small sac-like structures 
situated at bases of lobes resembling in form those of Diaspidiotus , those of each 
median lobe appearing nearly U-shaped, being very indistinctly separated at base; 
those of third lobes shaped like a pair of heavy dots, those of second lobes transi¬ 
tional in form between those of median and third lobes. There are also still a fourth 
pair, and even a rudimentary fifih. Spines rather small and short. Spine-like plates 
not large, not long, equalling in length the median lobes. Anal orifice about five 
times its diameter removed from anal end of body, well posterior to the level of the 
caudolateral glands. Five groups of ventral glands, in form mulberry-shaped, espe¬ 
cially the cephalolateral pair. Caudolaterals, about 20; cephalolaterals, about 30 or 
more; median group, 15.

Pseudoparlatoria serrulata, sp. nov. 
Distinguished at once from the other species of the genus so far known by the 
minutely serrulate chaiacter of the lobes. Five groups of circumgenital glands 
caudolaterals 11 to 15, cephalolaterals 12 to 15, median 2. Allied to P. noacki Ckll., 
rather than to P. parlatorioides Comst., as indicated by the five groups of glands, the 
latter species having only four. The median lobes are not so pointed as in noacki , but 
are rather rounded ; while not notched like parlatorioides (as in Comstock’s figure), 
they are rather inconspicuously notched nearer the base. The spine-like plates of 
first and second interlobular spaces are shorter than in either species, projecting but 
little beyond the end of the lobes. Lobes of second pair divided into three lobules. 
Fish tail structure between the median lobes hardly projecting beyond the lobes.

greenish gray; exuviae lateral, pale yellowish or yellowish-brown. £ scale small, 
subpyriform, about 1 mm. long, exuviae at the wider end; color grayish, with exuviae 
yellowish.
