372 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
Scale of /email -. — The scale of the female is very convex, with the exuvia- between 
the center and one side, and covered with secretion. The scale is gray, somewhat 
transparent, bo that it appears yellowish when it covers a living female; the promi- 
nence which covers the exuvhe is dark brown or black, usually with a central dot 
and concentric ring which are white. Ventral scale snowy white, usually entire. 
Diameter l£"' m (.06" inch). 
Female. — The body of the female is nearly circular in outline, bright yellow in color 
with more or less translucent blotches. The last segment presents the following 
characters: The groups of spinnerets are wanting. 
Only one pair of well-developed lobes, the median, present. These are prouiineut. 
Each one is furnished with a notch on each side; the notch on the mesal margin is 
distad of that on the lateral margin. The second and third pairs of lobes are repre- 
sented by the minute pointed projections of the margin of the body. 
The margin of the ventral surface of the segment is deeply incised twice on each 
side of the meson ; once laterad of the first lobe, and again between the rudimentary 
second and third lobes. The parts of the body wall forming the margin of these in- 
cisions are conspicuously thickeued. 
There are two simple tapering plates between the median lobes, two deeply and 
irregularly toothed or branched plates extending caudad of each incision, one usually 
simple and tapering plate between the incisions of each side, and two or three of the 
same character laterad of the second incision. 
The first, second, and third pairs of spines of each surface are situated near the 
lateral bases of the first, second, and third lobes, respectively; the fourth pair is 
situated at a little more than one half the distance from the median lobes to the 
penultimate segment. In each case the spine on the ventral surface is but little lat- 
erad of the one on the dorsal surface. 
Egg. — The eggs and newly hatched larva? are yellow. 
Male. — Only dead and shriveled males have been observed. 
Habitat. — On the bark of the trunk and limbs as well as the leaves and fruit of 
various trees and shrubs in California and Florida. 
Described from seventy-five females and very many scales. 
I have named this the greedy scale insect on account of the great 
number of plants upon which the species subsists. It also occurs in 
some localities in great numbers, being very destructive. This is 
especially the case en Euonymm japonicus a; Fort George, Fla. ; and in 
California on olive near San Buenaventura, and on mountain laurel 
( Umbellularia californica) at San Jose. 
Mr. Elwood Cooper, of Santa Barbara, Cal., who has had some ex- 
perience with this pest upon his olive trees, says that it is easily kept 
in check. According to his observations it flourished only upon those 
trees which are in an unhealthy condition, and as it is chiefly confined 
to the trunk and limbs it can be removed with a stiff brush and whale- 
oil soap solution. (Comstock Agr. Rep., 1880). 
The following insects also feed on the locust: 
COLEOPTERA. 
25. Spermopliagus robimm (Fabricius). Family Bruchichv (see Horn, 
Trans. Amer. Ent. Soc, iv, 311). 
26. Agrilus egenus Gory. Mining under the bark of the twigs and 
smaller branches, the beetles eating the leaves. (Chittenden, 
Ent. Amer., v, 219).
