Female : Oval in outline, with 3rd, 4th and 5th sejjments anterior from 
the pvgidium prominent. Median lobes fused to near the tip, diverging 
widely to rounded tips, then truncated obliquely toward the second lobes ; 
serrate or crenate on lateral margins. Inner lobule of second lobes serrate, 
produced on inner margin to a rounded tip ; outer lobule reduced, triangular, 
sharp-pointed, entire. Third lobe slightly produced, serrate. On the median 
line, a chitinous band extends anteriorly to base of median lobes, e.xpanding 
to a bulb-like thickening. Chitiuous bands extend obliquely toward this 
from outer margins. Second lobes slightly thickened on inner margins. 
frland-spines are arranged as follows : i, i, i, i — 2, 4 — 6 ; the first short 
and blunt. Second row of dorsal pores represented by i — 2 in anterior group; 
3rd row by 3 — 4 in anterior and 4—5 in posterior group ; 4th row by 3 — 5 in 
anterior and 5 — 7 in posterior group. Median group of circumgeniial glaud- 
orijices, 7 — 10; anterior lateral, 15 — 26; posterior lateral, 14 — 18. 
Remarks : The writer has found this scale on sy/vatica 
at four widely separated locations in .southeastern Ohio — Sugar 
Gro\-e, Fairfield county ; Newark, Licking county ; Soiner.set, 
Perr}’ count}' ; (Quaker City, Guernsey county. 
Prof. R. A. Cooley has kindly examined this species and pro- 
nounced it a valid one. 
Aspidiotus piceus, n. sp. PI. VIII. Fig. 66. 
Scale of female : i.S — 2mm. in diameter, flat, often sul)elliptical to oval, 
with subcentral exuviae ; black shading to dark gray toward margin, having 
the appearance of pitch covered with dust. The raised, shiny black, decidu- 
ous finst exuvia is surrounded by an indistinct ring-like depression. When 
rubbed the second orange exuvia appears. The young scales apj)ear not 
unlike the young male scales of .1 . pcniiciosus. When removed a white 
patch is left. 
Scale of male : Elliptical, mini, in length, black, with a di.stinct ring-like 
depression surrounding the lustrous black exuvia, the posterior flap shading 
to gray. 
Female : With one pair of lobes, well developed, prominent, broad, 
notched midway on lateral margin, with outer corners well-rounded off 
toward inner angle. Inner margins parallel, not close, bounded by large 
chitinous processes, which e.xtend somewhat reduced in deiusity around the 
outer margin to a denser jjrocess at outer base of lobe. Second and third 
lobes rudimentary, sometimes with inner angle of second lobe slightly devel- 
oped. Interlobular incisions broad and deep, bounded by elongated chitinous 
processes, the inner usuall}' the larger. There are two perforations anterior 
to median lobes on a level with the base of chitinous processes of first incision. 
Between the median and second, and second and third lobes are pairs of 
di-pointed spine-like plates, two-thirds of length of median lobes. On the 
dorsal surface there is a spine on each of the second and third lobes, and on 
the ventral surface each lobe bears a spine on the lateral margin laterad of dor- 
sal spine, also spines one-third and two-thirds of distance to penultimate seg- 
ment. First row of dorsal pores (between first and second lobes) of 2 ;
