Female scale longer than broad ; about 5 mm. in length, 4 — 4.5 mm. 

 broad, and 3.5 mm. high. Almost invariably attaching itself in or at 

 the forks of twigs, or at base of leaf petioles. Color bright ochreous 

 or sometimes lighter, marbled with a more reddish tint, sometimes 

 almost terra-cotta, with pale longitudinal dorsal band crossed at 

 segments by short more or less broken dark lines; otherwise the 

 segmentation is very indistinct. Small dark spots not prominent and 

 scattered rather promiscuously; numerous minute specks discernable 

 with hand-lens. 



Remarks : Found by the author at Pomeroy, 0., Aug. 28, 

 1903, on Q. rubruin, and later on the same host at Salem, and on 

 Q. vehitina, associated with E. pettiti Ehrh., at Lisbon. The 

 specimens from Q. ruhrum, at Salem, are much lighter in color 

 than those found on Q. vehitina, at Lisbon, 0.
