ature that agrees with this scale, so I have offered the following 

 description: 



Scale of female, grayish white, strongly resembling bark of 

 maple, in clusters, ventral scale well developed, the white sub- 

 stance annulated, scale circular, somewhat convex with the cephalic 

 margin extended, beyond the circumference, exuviae cephalad of 

 center covered by white secretion, when this is removed large 

 dark orange red exuviae appear. Scale i f o to 2 mm. 



Scale of male elongate oval, about ^^ nim. in length, ventral 

 scale well developed, but not arranged in rings, color of dorsal 

 scale somewhat darker. Exuviae between center and cephalic 

 margin, covered by white secretion, showing faint trace of dot and 

 ring, when this removed orange red exuviae appear. These exuviae 

 are much smaller than exuviae of female scale. 



Adult female, obovate, dark orange in color. There are three 

 pairs of lobes. The median lobes are prominent, notched on lat- 

 eral margin, line of mesal margin extends parallel with line of 

 meson. Chitinous processes at inner base of lobes. 



Second lobe pointed, erect, outer margin ranges from smooth 

 undulating line to a margin bearing three distinct notches. This 

 variation is shown by series of sketches (Fig. 16, a, b, c, d,). The 

 third lobe is also erect, ranging from inconspicuous to long, slender, 

 round lobe with notch (sketches Fig. 16, a, b, c, d, ). 



There are two pairs of incisions, with chitinous processes; these 

 chitinous processes remain constant. A large club-shaped process 

 on median side of first incision, a smaller one just opposite. The 

 process in second incision approaches a crescent. 



Plates are present, one or two inconspicuous caudad of first in- 

 'cision, always simple, one or two caudad second incision, gener- 

 ally forked. There is generally one simple plate between median 

 lobes. 



Spines, one on first lobe, usually two laterad of second lobe, the 

 same may be said of the two situated laterad of third lobe. An- 

 other pair of spines are always present on the lateral margin 

 between the third lobe and the penultimate segment. 



There are five groups of ventral glands; caudo-laterals range 

 from 5 to 8, cephalo-laterals 10 to 12, anterior 2 to 6. From many 

 scales and mounted specimens. 



The trunk of the maple bearing these scales was densly popu- 

 lated. Lawrence, Kans.
