FIGURE 33.—The euonymus scale, Unaspis euonymi, on Euonymus. 
on a mealy, whitewashed appearance in the spring and fall. 
Needles drop prematurely and twigs and branches are killed on 
heavily infested trees. The related species, fF’. theae (Green), a 
serious pest of camellia in the South, occurs on holly also. 
Lecanodiaspis tessalatus (Ckll.), the persimmon scale, a large 
hemispherical species, feeds on persimmon in the South. The sur- 
face of heavily infested limbs and trunks become rough, lumpy, 
or wartlike. The white peach scale, Pseudaulacaspis pentagona 
(Targ.), feeds on ash, dogwood, chinaberry, and lilac; Chrys- 
omphalus dictyospermi (Morgan) feeds on holly (in Virginia) ; 
and A. hederae feeds on chinaberry.
