uolohes. Second lobes iirominent, consisting of a large mesially in- 
clined inner lobule, showing one or two marginal notches, and a 
shorter, more erect, outer lobule, sometimes with one notch. Third 
lobe generally compressed, though clearly distinguishable, division 
into two lobules apparent, inner lobule generally entire, margin of 
outer lobule notched once or twice, spines appear singly, as shown in 
figure 2, iilate XIV, and grouped, beginning laterad of the median 
lobes, as follows : 1, 1-3, 1-2, 2-4, 4-8. The cireumgenital glands 
range in number : Median groups, 16-2(), anterio-laterals, 15-3(), pos- 
terio-laterals, 15-39. Of the thirteen specimens in which the glands 
were counted, ten had decidedly more glands upon the right side than 
upon the left side. Location and number of the dorsal glands shown 
in the figure. 
Male. The author of this species. Prof. W. Gr. Johnson, records 
two forms of males — “A perfect male with fully develojied wungs, and 
a pseudo-imago with rudimentary wings. 
Tliis siiccies is very common in Lawrence and vicinity, where I have 
taken it chiefly upon the outer branches of the white elm, but have 
also found it existing upon the trunk of the tree. I have received it 
from Floral, Cowley county, and Abilene, Dickinson county, upon 
badly infested twigs of the white elm. 
In the abundant material studied, from five localities in Douglas 
county, and at Abilene and Floral, little striking variation is to be 
noted. The plates are sometimes forked and sometimes simple, the 
limits of cireumgenital glands rather large; lobular crenulations 
appear at irregular intervals. The structural characteristics of the 
species in this latitude, however, appear to be fairly constant.

Seale of male, 0.9 to 1.3 mm. in length, sides parallel, diverging, 
.slightly oval, without carinic, exuviae lemon yellow, occupying about 
one-fourth the length of scale. 
Seale of female, 1.4 to 2 nun. in length, broadens posteriorly some- 
times abruptly, color favors the whitish coloring of the bark of host, 
sometimes obscured by the characteristic pruinose coloring of the 
bark; exuvim dark reddish brown, prominent, about one-fourth of 
length of scale ; little or no ventral scale. 
Female. Pygidium bears three pairs of lobes ; median lobes promi- 
nent, divergent from inner base, plainly serrate; second lobes consist 
of two lobules, the inner lobe the more jirominent, the outer lobe ex- 
tending but little if any bi'yond the marginal outline, faintly serrate ; 
the third 2 )air obscure, inner lobule noticeable, the outer reiiresented 
are arranged laterad of median lobes, beginning at the median lobe I,
